Trigeminal Neuralgia

Trigeminal Neuralgia

TRIGEMINAL NEURALGIA

Trigeminal Neuralgia also known as Tic Douloreuv is a disorder that affects the 5th cranial nerve that causes intense periodic pain in one or more trigeminal nerve branches. Normally affects the 2nd and 3rd branches.

Branches of the Trigeminal Nerve

The trigeminal nerve has 3 divisions i.e

  • The ophthalmic division(v1) that supplies the forehead, eyes, nose, meninges, paranasal sinuses and part of the nasal mucosa.
  • The maxillary division(v2) supplies the upper jaw, teeth, lip, cheeks, hard palate, maxillary sinus and part of the nasal mucosa.
  • The mandibular division(v3) supplies the lower jaw, teeth, lip, buccal mucosa, tongue, part of the external ear and the meninges.

Trigeminal neuralgia most commonly affects the second (V2) and third (V3) branches of the trigeminal nerve.

Causes of Trigeminal Neuralgia:

Causes of Trigeminal Neuralgia:

The exact cause of trigeminal neuralgia is not fully understood; however, factors depend on the subtype. The International Classification of Headache Disorders, Third Edition (ICHD-3) categorizes Trigeminal Neuralgia (TN) into three main types:

1. Classic Trigeminal Neuralgia (Classic TN):

  • This is the most common form of TN.
  • It is characterized by intense, sharp, electric-shock-like pain in the face, affecting the second (maxillary) or third (mandibular) branches of the trigeminal nerve.
  • The primary cause is believed to be compression of the trigeminal nerve by a nearby blood vessel, often an artery.

2. Secondary Trigeminal Neuralgia (Secondary TN):

This type of TN arises as a consequence of another underlying condition, such as:

  • Tumors: A tumor located along the trigeminal nerve can compress and irritate it.
  • Multiple Sclerosis (MS): The demyelination process in MS can damage the nerve fibers, leading to pain.
  • Other Neurological Disorders: Conditions like brainstem stroke or brain aneurysm can also contribute to secondary TN.

3. Idiopathic Trigeminal Neuralgia (Idiopathic TN):

  • This category refers to cases of TN where the underlying cause remains unknown.
  • Despite extensive investigations, no identifiable factor like a blood vessel compression or other neurological condition is found to be responsible.
General causative factors include

  1. Nerve Compression:

    • Explanation:: Compression of the trigeminal nerve by nearby structures, often blood vessels, leading to irritation and pain signals.
    • Example: Blood vessels impinging on the trigeminal nerve, causing compression and neuralgia.

  2. Demyelinating Plaques:

    • Explanation: Damage to the myelin sheath surrounding the trigeminal nerve, disrupting normal nerve function.
    • Example: Demyelination seen in conditions like multiple sclerosis.

  3. Herpes Virus Infection:

    • Explanation: Activation or infection of the trigeminal nerve by the herpes virus, contributing to inflammation and pain.
    • Example: Reactivation of the herpes simplex virus affecting the trigeminal nerve.

  4. Infection of the Teeth and Jaw:

    • Explanation: Infections in the teeth or jaw leading to inflammation and irritation of the trigeminal nerve.
    • Example: Dental infections spreading to the trigeminal nerve branches.

  5. Irritation from Flu-Like Illnesses:

    • Explanation: Inflammatory response due to flu-like illnesses affecting the trigeminal nerve.

  6. Trauma of the Teeth or Jaw:

    • Explanation: Physical injury to the teeth or jaw causing irritation of the trigeminal nerve.
    • Example: Dental trauma resulting in nerve irritation and subsequent neuralgia.

  7. Aneurysm Causing Pressure on the Nerve:

    • Explanation: Enlargement of an artery (aneurysm) putting pressure on the trigeminal nerve.
    • Example: Compression of the nerve by an adjacent aneurysm.

  8. Tumor:

    • Explanation: Presence of a tumor near the trigeminal nerve leading to compression and irritation.
    • Example: Tumor growth impacting the trigeminal nerve.

  9. Arteriosclerotic Changes of an Artery Close to the Nerve:

    • Explanation: Changes in artery walls close to the trigeminal nerve, potentially leading to compression.
    • Example: Arteriosclerosis affecting vessels in proximity to the trigeminal nerve.

Precipitating Factors of Pain:

  1. Light Touch:

    • Explanation: Even gentle touch or breeze on the face triggers severe pain due to the hypersensitivity of the trigeminal nerve.
    • Example: Brushing against the face lightly causing intense pain.

  2. Eating:

    • Explanation: Chewing and the mechanical process of eating can trigger neuralgic pain.
    • Example: Pain occurring during or after meals.

  3. Swallowing:

    • Explanation: The act of swallowing, which involves movement and muscle engagement in the face, can trigger pain.
    • Example: Pain associated with swallowing liquids or food.

  4. Talking:

    • Explanation: Articulating words and facial movements during speech may induce pain.
    • Example: Pain occurring while engaging in conversation.

  5. Sneezing:

    • Explanation: The sudden and forceful nature of sneezing can trigger intense facial pain.
    • Example: Pain experienced during or after sneezing.

  6. Shaving:

    • Explanation: The mechanical action of shaving involving contact with the face can lead to pain.
    • Example: Pain triggered by shaving activities.

Pathophysiology of Trigeminal Neuralgia 

Pathophysiology of Trigeminal Neuralgia

Trigeminal neuralgia (TN) is characterized by intense, stabbing, electric shock-like pain in the distribution of one or more branches of the trigeminal nerve (CN V). It is broadly classified into two main forms: classical (idiopathic) and symptomatic (secondary).

Classical (Idiopathic) Trigeminal Neuralgia: In the classical form, a definitive underlying cause is often not identified. However, microvascular compression of the trigeminal nerve near its exit from the brainstem is the most widely accepted etiological factor.

  • Vascular Compression: Aberrant arteries or veins (e.g., superior cerebellar artery) can compress the trigeminal nerve root, leading to demyelination of the nerve fibers. This demyelination disrupts normal nerve function and can cause ectopic impulse generation and aberrant cross-talk between different types of nerve fibers (Aβ, Aδ, and C fibers). The result is the paroxysmal pain characteristic of TN.
  • Gasserian Ganglion Irritation: Some studies suggest that irritation or compression of the Gasserian ganglion, where the three branches of the trigeminal nerve converge, can also contribute to classical TN.
  • Risk Factors: Classical TN is more prevalent in women and individuals over 50 years old.

Symptomatic (Secondary) Trigeminal Neuralgia: This form arises from an identifiable underlying condition that damages or compresses the trigeminal nerve.

  • Space-occupying lesions: Tumors in the cerebellopontine angle (CPA) such as acoustic neuromas, meningiomas, or epidermoid cysts can compress the trigeminal nerve.
  • Demyelination (Multiple Sclerosis): MS plaques in the brainstem can damage the trigeminal nerve, leading to TN. TN is more common in people with MS, and it often presents bilaterally in these individuals.
  • Other Structural Lesions: Aneurysms, arteriovenous malformations, or other vascular abnormalities can compress the nerve.

Differential Diagnosis

When evaluating a patient with suspected trigeminal neuralgia, it’s important to consider other conditions that can cause facial pain. The differential diagnosis includes:

  • Dental Pathology: Toothaches, abscesses, or temporomandibular joint (TMJ) disorders can mimic TN pain.
  • Herpes Zoster: Postherpetic neuralgia following a shingles outbreak can cause persistent facial pain.
  • Nasopharyngeal and Paranasal Pathology: Sinus infections or tumors in the nasal cavity or sinuses can cause facial pain.
  • Cervical Artery Dissection: Although rare, dissection of the internal carotid or vertebral artery can cause facial pain.
  • Giant Cell Arteritis: This inflammatory condition can cause facial pain, particularly in older adults.
  • Cluster Headaches and Migraines: These primary headache disorders can sometimes present with facial pain.
  • Unstable Angina: In rare cases, pain from unstable angina can radiate to the jaw and face, mimicking TN.
  • Trigeminal Neuropathy: Sensory loss or other neurological deficits may indicate a different underlying condition than TN

Investigations and Diagnosis of Trigeminal Neuralgia (TN)

Diagnosing TN primarily relies on a thorough medical history and physical examination, as there is no single definitive test.

1. Detailed Medical History:

  • Pain Description: Ask about the character, intensity, duration, frequency, and triggers of the pain.
  • Onset and Progression: Inquire about when the pain started, how it has changed over time, and whether it’s been getting worse.
  • Previous Medical History: Information on previous illnesses, neurological conditions, or surgeries is relevant. Ask about current medications and supplements.

2. Physical Examination:

  • Neurological Examination: Assess the patient’s reflexes, sensation, and motor function, particularly in the face and trigeminal nerve distribution.
  • Palpation: The doctor may palpate the jaw and face to identify any areas of tenderness or trigger points.

3. Imaging Studies:

  • Magnetic Resonance Imaging (MRI): An MRI scan can help rule out other neurological conditions that can cause facial pain, such as tumors, MS, or vascular malformations.
  • Computed Tomography (CT) Scan: A CT scan can also help visualize the anatomy of the trigeminal nerve and surrounding structures.

Medical Management of Trigeminal Neuralgia:

Aims of Management

  • Control Pain: Reduce the frequency and severity of pain attacks.
  • Improve Quality of Life: Enable individuals to engage in daily activities without significant pain interference.
  • Prevent Complications: Minimize the risk of potential complications such as depression, anxiety, and social isolation.

Pharmacologic Therapy:

1. Anticonvulsants: Carbamazepine (Tegretol) and oxcarbazepine (Trileptal) are the first-line medications for TN.

  • Carbamazepine (Tegretol): Reduces transmission of impulses at nerve terminals, relieving pain. Adult dose at 100mg. Given with meals to minimize side effects.
  • Monitoring and Side Effects: Patients are observed for side effects, including nausea, dizziness, drowsiness, and potential aplastic anemia. Long-term therapy requires monitoring for bone marrow depression.

2. Antidepressants: Tricyclic antidepressants like amitriptyline (Elavil) can also be effective in pain management.

3. Pain Relievers: Over-the-counter pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil) may provide temporary relief.

4. Alternative Medications: Gabapentin and baclofen are utilized for pain management. If pain control remains inadequate, phenytoin (Dilantin) may be added as adjunctive therapy. Baclofen: This muscle relaxant may help reduce muscle spasms and pain.

Surgical Management:

5. Microvascular Decompression: This surgical procedure involves moving the blood vessel that is compressing the trigeminal nerve away from the nerve.

6. Percutaneous Radiofrequency: This procedure uses heat to destroy the trigeminal nerve fibers responsible for pain.

7. Gamma Knife Radiosurgery: Utilizes stereotactic magnetic resonance imaging (MRI) to identify the trigeminal nerve. Followed by gamma knife radiosurgery for precise intervention.

8. Glycerol Injection: A glycerol solution is injected into the trigeminal nerve, interrupting pain signals.

Nursing Management:

9. Identification of Triggers: Assist patients in recognizing triggers for facial pain (e.g., hot or cold stimuli, jarring motions). Teach strategies like using cotton pads and room temperature water for facial care.

10.Oral Hygiene: Instruct patients to rinse their mouths after eating when tooth brushing causes pain. Perform personal hygiene during pain-free intervals.

11. Dietary Guidance: Advise patients to consume food and fluids at room temperature. Suggest chewing on the unaffected side and opting for soft foods.

12. Emotional Well-being: Recognize and address anxiety, depression, and insomnia common in chronic pain conditions. Implement appropriate interventions and referrals.

13. Postoperative Care: Perform neurologic checks to assess facial motor and sensory deficits postoperatively.

14. Eye Care: Instruct patients not to rub the eye if sensory deficits occur post-surgery. Assess for eye irritation or redness and administer artificial tears if prescribed.

15. Physical Therapy: Specific exercises and techniques can help reduce muscle tension and improve facial movement.

16. Eating and Swallowing: Observe patients for any difficulty in eating and swallowing foods of different consistencies.

17. Lifestyle Modifications: Avoiding triggers, maintaining a regular sleep schedule, and reducing stress can help manage TN.

18. Cognitive-Behavioral Therapy (CBT): CBT can teach coping skills for managing pain and stress.

19. Support Groups: Encourage patients to join support groups for emotional and informational support.

REVIEW OF THE ANATOMY AND PHYSIOLOGY OF NERVOUS SYSTEM

Anatomy of the Nervous System

The nervous system can be separated into parts based on structure and on function:

Structurally, it’s organized into the central nervous system (CNS) and the peripheral nervous system (PNS). 

The CNS consists of the brain and spinal cord, both of which originate in the embryo. The PNS comprises all neural structures outside the CNS, connecting it to the rest of the body. These structures develop from neural crest cells and as extensions of the CNS itself. The PNS includes spinal and cranial nerves, visceral nerves and plexuses, and the enteric nervous system.

Functionally, the nervous system is divided into somatic and visceral components. The somatic nervous system (from the Greek ‘soma,’ meaning body) innervates structures derived from somites, such as skin and most skeletal muscle. 

It’s primarily responsible for receiving and responding to external environmental information. The visceral nervous system (from the Greek ‘viscera,’ meaning guts) innervates organ systems and other visceral elements like smooth muscle and glands throughout the body. It mainly detects and responds to information about the body’s internal environment. The neuron, with its cell body, axon, and synapse, is the functional unit of the entire nervous system.

Structural Division:
  • Central Nervous System (CNS): Composing the brain and spinal cord.
  • Peripheral Nervous System (PNS): Includes structures outside the CNS connecting it to the body.
Functional Division:
  • Somatic Part: Innervates structures from somites (skin, skeletal muscles). Responds to external environmental stimuli.
  • Visceral Part: Innervates organ systems, smooth muscles, and glands. Detects and responds to internal environmental stimuli.

FUNCTIONS OF NEURON STRUCTURES
  • Nucleus – controls the entire neuron.
  • Dendrite – receives stimulus and carries its impulses toward the cell body.
  • Cell Body (soma) – has a nucleus & cytoplasm. It acts as a factory of the neuron. It produces all protein for the dendrites and neurotransmitters.
  • Axon – fiber which carries impulses away from the cell body i.e it forms a conduction region for the neuron.
  • Schwann Cells/ neurolemmocyte – cells which produce myelin or fat layer in the Peripheral Nervous System (axon maintenance and regeneration) It’s a glial cell that wraps the nerve fibre in PNS.
  • Myelin sheath – dense lipid layer which insulates the axon ( makes the axon look gray) It speeds-up nerve transmission.
  • Node of Ranvier – gaps or nodes in the myelin sheath. They speed up nerve transmission.
  • Axon terminals – form junctions with other cells.
There are three types of Neurons
  • Sensory neurons – bring messages to CNS.
  • Motor neurons – carry messages from CNS.
  • Interneurons – between sensory & motor neurons in the CNS.

Neuron – Functional Unit:

  • Composed of nucleus, dendrites, cell body (soma), axon, Schwann cells, myelin sheath, Node of Ranvier, and axon terminals.
  • Three types: sensory neurons (to CNS), motor neurons (from CNS), and interneurons (between sensory and motor neurons in CNS).

Other Nervous System Cells:

  • Satellite Cells: Surround neuron cell bodies in ganglia. Maintain a micro-environment and provide insulation.
  • Ependymal Cells: Line CNS cavities, secrete cerebrospinal fluid, and form choroid plexuses.
  • Oligodendrocytes: Wrap around CNS neurons to produce myelin sheath.
  • Astrocytes: Glial cells in the CNS. Anchor neurons to blood vessels and form the blood-brain barrier.
  • Microglia: Monocytes in the nervous system. Move to damaged tissue for phagocytosis.

CENTRAL NERVOUS SYSTEM

Brain Anatomy & Physiology.

applied anatomy of the brain
Cerebrum:
  • Largest brain structure with frontal, temporal, parietal, and occipital lobes.
  • Divided into hemispheres by the longitudinal cerebral fissure.
  • Cerebral cortex (gray matter) and subcortical white matter.
  • Responsible for memory, sensory perception (pain, temperature, touch, sight, hearing, taste, smell), and control of skeletal muscle contractions.
Cerebellum:
  • Located behind the pons, below the occipital lobe.
  • Oval-shaped with hemispheres separated by vermis.
  • Contains gray and white matter.
  • Coordinates voluntary muscle movement, maintains posture and balance, and contributes to learning and language processing.
Brain Stem (Midbrain and Hindbrain – Pons & Medulla Oblongata):
  • Midbrain surrounds the cerebral aqueduct, connecting cerebrum and pons.
  • Pons, in front of the cerebellum, have nuclei and nerve fibers.
  • Medulla oblongata extends from the pons, continuous with the spinal cord, containing gray and white matter.
  • Midbrain acts as a relay station for ascending and descending nerve fibers, connecting cerebrum with lower brain fibers and spinal cord.
  • Pons collaborates with the medulla to control respiration.
  • Medulla oblongata controls respiration, cardiovascular function, and reflexes (vomiting, coughing, sneezing, swallowing). 
Diencephalon (Thalamus, Hypothalamus):
  • Connects cerebrum and midbrain.
  • Houses thalamus (gray and white matter masses) and hypothalamus (below thalamus, connected to pituitary gland).

Thalamus

  • Relays and distributes impulses from various brain parts to the cerebral cortex.
  • Plays a role in memory processing.

Hypothalamus

  • Controls the autonomic nervous system.
  • Regulates appetite, thirst, body temperature, water balance, emotional reactions, and sexual behavior.
  • Influences sleeping and waking cycles through melatonin from the pineal gland.
  • Secretes ADH (antidiuretic hormone) and oxytocin.

Anatomy of the Spinal Cord

  • Cylindrical shape with circular to oval cross-section and a central canal.
  • Comprises 31 pairs of spinal nerves, each with sensory (dorsal root) and motor (ventral root) fibers.

Physiology of the Spinal Cord:

Spinal cord provides communication between brain and the peripheral nerves. Tracts of white matter of the spinal cord carry sensory impulses to the brain and motor impulses from the brain to the skeletal muscles.

The grey matter of the spinal cord is a site of integration of reflexes which is rapid involuntary action in relation to a particular stimulus.

  • Facilitates communication between the brain and peripheral nerves.
  • White matter tracts carry sensory impulses to the brain and motor impulses from the brain to skeletal muscles.
  • Grey matter serves as the site for reflex integration, rapid involuntary actions in response to stimuli.
cross section of the spinal cord

Meninges:

Three connective tissue coverings surrounding and protecting the brain and spinal cord.

  • Dura Mater: Thickest and outermost layer, continuous with cranial dura mater. The spinal dura mater is continuous with the cranial dura mater at the foramen magnum of the skull and is the outermost meningeal membrane. In the cranial cavity, one layer of the dura mater is fused to the bone and represents the periosteum, but the spinal dura mater is separated from the bones of the vertebral canal by an extradural space. Inferiorly, the Dural sac dramatically narrows at the level of the lower border of vertebra SII and forms an investing sheath for the pial part of the filum terminale of the spinal cord. The dural part of the filum terminale attaches to the posterior surface of the vertebral bodies of the coccyx.
  • Arachnoid Mater: Thin, delicate membrane against the internal surface of the dura mater. This is a thin delicate membrane against, but not adherent to, the deep surface of the dura mater. It is separated from the pia mater by the subarachnoid space. The arachnoid mater ends at the level of vertebra SII. The sub-arachnoid space contain CSF.
  • Pia Mater: Adherent to the brain and spinal cord, extends into the anterior median fissure, and forms the denticulate ligament. It extends into the anterior median fissure and reflects as sleeve-like coating onto posterior and anterior rootlets and roots as they cross the subarachnoid space. As the roots exit the space, the sleeve-like coatings reflect onto the arachnoid mater. On each side of the spinal cord, a longitudinally oriented sheet of pia mater (the denticulate ligament) extends laterally from the cord toward the arachnoid and dura mater. Because the subarachnoid space can be accessed in the lower lumbar region without endangering the spinal cord, it is important to be able to identify the position of the lumbar vertebral spinous processes. The LIV vertebral spinous process is level with a horizontal line between the highest points on the iliac crests. In the lumbar region, the palpable ends of the vertebral spinous processes lie opposite their corresponding vertebral bodies. The subarachnoid space can be accessed between vertebral levels LIII and LIV and between LIV and LV without endangering the spinal cord.

Spinal Nerves

Spinal nerves, like most nerves, contain both sensory and motor fibers. They are named and numbered according to the region of the vertebral column from which they originate: 

  • 8 cervical nerves (C1-C8), 12 thoracic nerves (T1-T12), 
  • 5 lumbar nerves (L1-L5), 
  • 5 sacral nerves (S1-S5), and 
  • 1 coccygeal nerve. 

Nerve C1 emerges between the cranium and the atlas (first cervical vertebra). All other spinal nerves emerge below the vertebra (or former vertebra, in the case of the sacrum) corresponding to their number.

A plexus is a network of interconnected nerve fibers that recombine to form new, named peripheral nerves.

Dermatomes are areas of skin and muscle innervated by specific spinal nerves. A dermatome map (as shown in the figure) is a valuable diagnostic tool. It helps determine the origin of somatic pain, numbness, or tingling, especially when these symptoms result from pressure or inflammation of the spinal cord or nerve roots.

  • Dermatomes are somatic or musculocutaneous areas served by fibers from specific spinal nerves.
  • Dermatome map aids in diagnosing somatic pain, numbness, tingling caused by spinal cord or nerve root pressure or inflammation.

Myotome:

  • Region of skeletal muscle innervated by a single nerve or spinal cord level.
  • Most muscles receive input from multiple spinal cord levels.

Orthopedic Nursing Care

Orthopedic Care

Orthopedic care is concerned with preventing, recognizing, and treating injuries, diseases, and ailments that affect the musculoskeletal system of the body.

This system consists of muscles, tendons, ligaments, and other connective tissues that enable a human being to perform physical activity.

Orthopedic care involves treating common problems such as;

1. Musculoskeletal Trauma:

  • Fractures: Broken bones ranging from simple hairline fractures to complex compound fractures.
  • Dislocations: Displacement of bones from their normal joint positions.
  • Sprains and Strains: Injuries involving ligaments (sprains) and muscles/tendons (strains).
  • Soft Tissue Injuries: Bruises, contusions, lacerations, and other damage to muscles, ligaments, and tendons.

2. Sports Injuries:

  • ACL Tears: Tears in the anterior cruciate ligament, often occurring during pivoting or sudden stops.
  • Rotator Cuff Tears: Tears in the muscles and tendons surrounding the shoulder joint.
  • Hamstring Injuries: Muscle strains or tears in the hamstring muscles at the back of the thigh.
  • Achilles Tendinitis: Inflammation of the Achilles tendon, commonly seen in athletes.

3. Degenerative Diseases:

  • Osteoarthritis: A common condition characterized by wear and tear on joint cartilage.
  • Rheumatoid Arthritis: An autoimmune disease causing inflammation in the joints.
  • Spinal Stenosis: Narrowing of the spinal canal, often causing pain, numbness, and weakness.
  • Osteoporosis: Weakening of the bones, making them more prone to fractures.

4. Infections:

  • Osteomyelitis: An infection of the bone, often requiring antibiotics or surgery.
  • Septic Arthritis: An infection within a joint, causing pain, swelling, and redness.
  • Tendonitis: Inflammation of a tendon, which can be caused by infection or overuse.

5. Tumors:

  • Bone Cancer: Malignant tumors that develop in the bones, requiring treatment with surgery, chemotherapy, or radiation.
  • Benign Bone Tumors: Non-cancerous growths that can cause pain or pressure.

6. Congenital Disorders:

  • Scoliosis: A sideways curvature of the spine.
  • Clubfoot: A condition where the foot is turned inward at birth.
  • Hip Dysplasia: A condition where the hip joint doesn’t develop properly.

7. Other Common Orthopedic Issues:

  • Back Pain: A widespread issue that can be caused by a variety of factors, including muscle strain, spinal problems, and disc herniation.
  • Carpal Tunnel Syndrome: A condition affecting the median nerve in the wrist, causing numbness and tingling in the hand.
  • Knee Pain: Can be caused by osteoarthritis, injuries, or overuse.
  • Shoulder Pain: Can be caused by rotator cuff tears, arthritis, or nerve compression.

  • Traction
  • Splints
  • Non-surgical procedures
  • Surgical procedures (such as ligament repair)
DRESSINGS & BANDAGING
DRESSINGS & BANDAGING

A dressing is a sterile material applied to a wound or surgical site to promote healing and protect it from infection or further injury.

A dressing is any protective cover for the wound. It is usually a cotton material.

Uses of Dressings

  1. Protection from Infection: Dressings act as a barrier to prevent microbial contamination.
  2. Control Bleeding: Dressings can help apply pressure to a wound, assisting in controlling bleeding.
  3. Absorption of Discharge: They are designed to absorb any fluid or discharge from the wound, reducing the risk of infection and promoting a healthy healing environment.
  4. Prevent Further Injury: Dressings help protect the wound from external impacts and irritants, preventing further injury to the area.
  5. Moisture Management: Dressings help maintain a moist wound environment, which can enhance healing.
  6. Pain Reduction: Certain dressings can provide cushioning and support around a wound, reducing discomfort.
  7. Promotion of Healing: Some dressings contain agents that promote healing, such as growth factors or antimicrobial treatments.

General Rules for Applying Dressings

  1. Wash your hands thoroughly before and after applying the dressing, whenever possible.
  2. If the wound is not too large and bleeding is under control, clean it and the surrounding skin before applying the dressing.
  3. Avoid touching the wound or any part of the dressing that will be in contact with the wound.
  4. Never talk or cough over a wound or the dressings.
  5. If necessary, cover non-adhesive dressings with cotton wool pads and a bandage to control bleeding and absorb discharge.
  6. Use a swab soaked in antiseptic or disinfectant to clean the wound only once.
  7. If the dressing slips over a wound before it is fixed in place, discard it and use a fresh one, as the first may have picked up germs from the surrounding skin.
  8. Always place dressings directly onto the wound. Never slide it in from the side.
BANDANGING

A bandage is a piece of gauze or cloth material used for any of the purposes to support, hold or to immobilize any part of the body. 

A bandage is a strip of material (such as cloth or elastic) used to secure, support, or protect a dressing or injured area. 

Bandaging is a technique of application of specific roller bandages to different parts of the body.

Bandaging refers to the process of applying a bandage to a wound or injured body part.

Purposes of Bandaging

  • To Cover and Retain Dressings: Bandages help keep dressings securely in place, ensuring proper protection for the wound.
  • To Protect a Wound: They offer a barrier against dirt, bacteria, and other contaminants that can lead to infection.
  • To Support Injuries: Bandages provide support for injured areas, such as sprains, aiding in immobilization and stability.
  • To Compress: They apply pressure to control bleeding or reduce swelling by compressing the affected area.
  • To Secure Dressings: Bandages keep dressings in place, ensuring that the wound is adequately protected and that the dressing functions effectively.
  • To Immobilize Fractures: Certain bandages, such as plaster of Paris casts, immobilize fractures, allowing them to heal properly.
  • To Control Bleeding: Bandages help apply pressure to a wound, assisting in controlling bleeding.
  • To Restrict Movement: Bandages can limit movement in injured areas, promoting healing and reducing pain.

Types of Bandages

1. Triangular Bandages: This type of bandage is used in emergency treatment and first aid. It can be utilized for:

    • Head Bandage: Used to cover and protect head injuries.

    • Sling: Provides support for an injured arm.

2. Roller Bandages: Long strips of cloth or elastic material rolled up for easy application. They can be used to apply compression and secure dressings in various ways:

    • Circular: Applied in circles around the wound.

    • Spiral: Wrapped in a spiral manner to cover the area.

    • Recurrent: Used to cover areas like the stump of an amputated limb.

3. Plaster Bandages: Made from plaster of Paris, these bandages immobilize fractures of bones, providing necessary support during healing.

4. Adhesive Bandages: These are used for fractures at the clavicle bone, providing support and securing the area.

5. Gauze Bandages: Made of woven or non-woven fabric, these bandages are used to cover wounds and absorb exudate.

6. Crepe Bandages: These elastic bandages allow for a degree of stretch when applied, determining the amount of pressure they exert. They are widely used for sprains and strains.

To prevent injury.

 

Materials Used to Make Various Bandages

Material

Description

Cotton

Heavy weaves are used for slings, thin porous ones from open weave bandages which are cheap, light, and disposable. Firmer ones with a fast edge can be washed repeatedly.

Domette

This woven material with a slightly fluffed surface makes a firm supporting bandage, which has some resilience but can be used to give firm support.

Crepe

These bandages are elastic, and the degree to which they are stretched when applied determines the amount of pressure they exert. They are widely used.

Plaster

Plaster muslin is the basis for making plaster of Paris bandages.

Stockinet

Used beneath plaster.

Proprietary Tubular Material

Such as tube gauze or Hetelast.

Bandaging patterns
Bandaging patterns

Bandaging patterns refer to the specific techniques used to apply bandages effectively to secure dressings, support injured areas, and control bleeding. The choice of pattern depends on the location and type of injury, as well as the desired outcome (e.g., compression, immobilization). 

Figure of eight: This pattern wraps the bandage in a figure-eight shape around the joint, creating a shape that stabilizes while still allowing for mobility.

Use: Mainly used for bandaging joints such as the knee, ankle, or elbow to provide support while allowing limited movement.

To ensure firmness and neatness.

5

Bring the bandage which circles the victim’s head over the fore head covering and fixing the bandage which crosses the scalp. The bandage is then brought back over the scalp.

 

6

Ensure that each turn of the bandage covers 2/3 of the previous turn.

Adheres snugly to the body part.

7

Cross it again at the back and fix it using encircling bandage and turn back over the scalp to the opposite side at the central line covering the other margin of its original turn.

 

8

Repeat the back and forward turns to alternate side of the center, each one begin in front by the encircling bandage until the whole scalp is covered.

 

G. Recurrent Bandaging

1

Overlap each layer of bandage by half to two-thirds the width of the strip; wrap firmly but not tightly as you work, ask the patient if it feels comfortable. Loosen the bandage if there is tingling, itching, numbness, or pain.

To provide firmness.

2

Stand facing the patient and take a fixing turn.

To observe the facial expression.

3

Carry the bandage upward across the front of the limb at 45° rounds behind it at the same level and downwards over the front to cross the first turn at a right angle.

To provide firmness and neatness.

4

Repeat these turns until the limb has been sufficiently covered.

 
Splints

ORTHOPAEDIC SPLINTS

Orthopaedic splints are medical devices used to immobilize, support, or protect a broken, fractured, or injured limb or joint. 

They are made from materials such as plaster, fiberglass, or various synthetic materials, and can be either rigid or flexible. Splints are designed to prevent movement in the injured area, thereby facilitating healing and preventing further injury.

Following the diagnosis of an unstable injury, a splint may be the best treatment option and is  defined as an external device used to immobilize an injury or joint and is most often made out of plaster.

 A splint must be differentiated from a cast, to determine the best form of immobilization based on the clinical scenario. Contrary to a splint, a cast is a circumferential application of plaster that rigidly immobilizes a particular joint or fracture. Because of their circumferential restrictive nature, casts are not placed in the acute post-injury setting as they do not accommodate for soft tissue swelling.

Indications for Orthopaedic Splints

Splints are placed to immobilize musculoskeletal injuries, support healing, and prevent further damage. The indications for splinting are broad but commonly include:

  1. Temporary stabilization of acute fractures, sprains, or strains before further evaluation or definitive operative management.
  2. Immobilization of a suspected occult fracture (such as a scaphoid fracture).
  3. Severe soft tissue injuries requiring immobilization and protection from further injury.
  4. Definitive management of specific stable fracture patterns.
  5. Peripheral neuropathy requiring extremity protection.
  6. Partial immobilization for minor soft tissue injuries.
  7. Treatment of joint instability, including dislocation.
  8. Fractures to stabilize broken bones, ensuring proper alignment during healing.
  9. Post-surgical immobilization following orthopedic procedures to maintain healing and alignment.
  10. Dislocations to stabilize a joint until it can be properly repositioned and treated.
  11. Tendon injuries to immobilize the area for healing.
  12. Chronic pain conditions, such as carpal tunnel syndrome, where splints alleviate pain by providing support.
  13. Bone stabilization in pediatric patients for fractures where traditional casting may be impractical.
  14. Temporary stabilization before surgery to prepare the area for intervention.

Indications for Splinting

Splints are used in various musculoskeletal conditions to immobilize injuries, support healing, and prevent further trauma. The most common indications include:

Condition

Purpose of Splinting

Acute fractures, sprains, or strains

Provides temporary stabilization before further evaluation or surgery.

Occult fractures (e.g., scaphoid fracture)

Immobilization of suspected fractures that may not appear on initial imaging.

Severe soft tissue injuries

Prevents further injury and allows proper healing.

Stable fractures

Can serve as definitive treatment in specific fracture patterns.

Peripheral neuropathy

Protects affected extremities from accidental trauma.

Minor soft tissue injuries

Partial immobilization to reduce pain and movement.

Joint instability (e.g., dislocations)

Prevents excessive motion and supports joint recovery.

Equipment Required for Splint Application

Before applying a splint, it is essential to gather and organize all necessary materials:

Equipment

Purpose

Sheet or towel

Protects patient’s clothing.

Stockinette

Soft stretchable fabric placed under the splint for skin protection.

Under-cast padding (cotton padding)

Provides cushioning and prevents skin irritation.

Plaster or padded fiberglass

Forms the rigid supportive structure of the splint.

Water bucket (cool water)

Activates plaster or fiberglass materials.

Elastic bandage

Secures the splint in place while allowing for swelling.

Sling (for upper extremity injuries)

Supports the injured limb.

C-arm X-ray (if fracture reduction is attempted)

Confirms proper alignment of fractured bones before splint application.

General Steps for Splint Application

Pre-Splinting Preparation

✅ Ensure adequate pain management – Provide analgesia or sedation as necessary to promote muscle relaxation and facilitate fracture reduction.
✅ Address soft tissue injuries – Clean and dress any open wounds before applying the splint.
✅ Prepare the affected area – Apply a stockinette circumferentially around the injury, ensuring it extends beyond the splinting area to protect the skin.

Splint Application Process

1️⃣ Pad bony prominences (e.g., elbow, knee, calcaneus) with 1–2 cm of soft padding to prevent pressure sores or necrosis.
2️⃣ Apply 2–3 layers of cast padding (0.25 cm to 0.5 cm) to provide additional cushioning.
3️⃣ Reduce any fracture by restoring bone length, alignment, and rotation (radiographic confirmation may be required).
4️⃣ Activate plaster or fiberglass sheets by saturating them in cool water.
5️⃣ Layer and laminate the splinting material, pressing the sheets together to increase strength.
6️⃣ Mold the splint around the injured area, ensuring proper support and resistance to deforming forces.
7️⃣ Do not completely encircle the limb – Splints must accommodate for swelling. If circumferential overlap occurs, the splint should be cut open after setting.
8️⃣ Fold the stockinette edges over the splint to protect the skin from sharp plaster or fiberglass edges.
9️⃣ Secure the splint with an elastic bandage – Apply it loosely to hold the splint in place while allowing for soft tissue expansion. Avoid direct contact with the skin.
🔟 Reassess the patient’s neurovascular status – Check for pulses, capillary refill, sensation, and motor function. Any compromise requires immediate splint removal and reassessment.
11. Educate the patient about splint care, warning signs (e.g., numbness, swelling, pain), and follow-up instructions.

Types of Splints

Splints are categorized based on their location and function.

Common Upper Extremity Splints

Splint Type

Indication

Coaptation Splint

Used for humeral fractures, preventing excessive movement.

Sugar Tong Splint

Immobilizes the forearm and prevents wrist/elbow rotation.

Posterior Long Arm Elbow Splint

Used for elbow dislocations and fractures.

Ulnar Gutter Splint

Supports 4th and 5th metacarpal fractures (boxer’s fracture).

Radial Gutter Splint

Immobilizes fractures of the 2nd and 3rd metacarpals.

Volar/Dorsal Short Arm Splint

Used for wrist sprains and carpal bone fractures.

Thumb Spica Splint

Commonly used for scaphoid fractures and thumb injuries.

Common Lower Extremity Splints

Splint Type

Indication

Posterior Long Leg Splint

Used for tibial fractures, knee ligament injuries.

Posterior Short Leg Splint

Immobilizes ankle fractures and foot injuries.

Posterior Short Leg Splint with Stirrups

Provides added stability for ankle fractures and severe sprains.

Complications of Splinting

Although splints are effective in immobilizing injuries, they can lead to complications if not applied correctly.

Complication

Cause & Risk Factors

Loss of fracture reduction

Movement or improper molding of the splint may cause the fracture to shift out of alignment.

Skin irritation or breakdown

Inadequate padding or excessive pressure may result in skin ulcers or irritation.

Joint stiffness

Prolonged immobilization can lead to decreased range of motion.

Thermal injury

Plaster generates heat when setting, and excessive layers may cause burns.

Neurovascular compromise

Tight splints may cause acute carpal tunnel syndrome or nerve compression.

Compartment syndrome

If a splint becomes circumferential (like a cast), it may increase pressure, leading to vascular compromise and tissue ischemia.

PRE-OPERATIVE CARE OF PATIENTS

Objectives

  1. Identify the requirements for pre and post operative care.
  2. Prepare requirements for pre and post operative care.
  3. Perform pre and post operative care.

Preparation for surgery should begin as soon as the  doctor makes a diagnosis and decides that an operation is necessary. From that moment on, the patient and relatives are faced with the decision of accepting this treatment and its consequences or not.
The  doctor should tell the patient and family why an operation must happen, what will be done and what the probable outcome will be.
An appointment for admission is now arranged depending on the acuteness of the illness, period of preoperative care and the amount of time the patient requires to make necessary arrangements regarding his family, financial matters and work.

1. Admission: patient may be admitted a day before or several weeks or days in a surgical ward for a planned surgery, depending on the extent of the pre-operative treatment, e.g., alcoholics, wasted cancer patients, so that their nutritional and electrolyte status and underlying conditions are treated before
surgery.

2. Rapport: Patient and significant others are received by the nurse, given seats, greeted, and introduction of names done by the nurse. Patient is showed a bed, and he is introduced to the ward or room-mates, he is showed the ward environment, i.e. the latrines, shelters, stores, kitchen, sluice room and other
departments within the hospital that are necessary for him to know, visiting hours, meal times.

3. Physical preparations and History: History of the disease is taken, starting from the present main complaint, and other associated complaints presently, history of previous illness, or operation done is noted, any drugs taken by the patient, any allergy to any drug, any dietary restrictions, patient’s occupation, religion, marriage status, etc.

4. Vital Observations are taken and recorded to provide a baseline for future comparisons, weighing is done and the surgeon is informed to come and review the patient.

5. Psychological preparation: There is need to prepare the patient before surgery psychologically because patients always have fears when faced with the fact of undergoing an operation, and this depends on the individual basic personalities, habitual reactions to stress over the years, general state of mental health, and the preconceptions that they have concerning surgery and anesthesia. These fears include; fear of unknown, post-operative pain, discovery of cancer, the loss of organs that have special meaning
for them, the hazard of death or fear of what other friends have been telling them about surgery, hazards of anesthesia, vulnerability while unconscious, threat of loss of job and financial security, loss of social and familial roles, and the problem of being separated from family members and former activities.
These fears cause anxiety in patients going for surgery and these can be expressed in a variety of behaviors such as: becoming silent and withdrawn, hopeless and helpless, childish, aggressive and disobedient, evasive, tearful.

Measures to alley the patient’s anxiety

  1. Information and Orientation: Patient is given explanations or printed information about hospital routines, visiting hours, meal times, specific locations and general orientation to the hospital environment.
  2. Procedure Explanations: Give full explanations of all procedures the patient may undergo, covering the pre-operative, intra-operative, and postoperative phases.
  3. Reasoning and Discomfort: Patient is made aware of the reasons for the various procedures to be done on him and any discomfort that may be experienced, ensuring the patient understands the reasons for the intervention.
  4. Collaborative Communication: There must be prior consultation between a nurse and the  doctor in order to maintain the uniformity and accuracy of the information to be given to the patient.
  5. Questioning and Clarification: Patient should be given a chance to ask questions concerning the operation and the postoperative period, providing reassurance and addressing any concerns.
  6. Information Management: Give only as much information as the patient wishes to know, as too much information given in a short time may create more anxiety or when given at a wrong time, like some few hours to operation.
  7. Peer Support: Patients going for major surgery like mastectomy, colostomy, may benefit from being introduced to people who have successfully recovered from these operations.
  8. Occupational Therapy: Occupational therapy can be arranged for patients who are facing an extended preoperative period, e.g. games, handicrafts, television to distract the patient and ease the fear and loneliness.
  9. Family and Friends: Encourage visits from family members and friends to have time with the patient, to provide companionship and emotional support.
  10. Religious Support: Ascertain the patient’s religious preference and arrange for a priest, minister, or rabbi to visit if the patient so desires.
  11. Age-Appropriate Language: A child should be told in simple language appropriate to his age and level of development what to expect before and after surgery.
  12. Honesty and Clarity: The child should never be told lies. Be honest when telling him about surgery, tests, pain, stitches, etc.
  13. Socialization: Let the child be with other hospitalized children for easy adjustment.

  • Note: handling fears in this way can smooth the patient’s operative course. Studies show that the calm,emotionally prepared pre-operative patient is able to withstand the induction of anesthesia better and also experiences less postoperative nausea and vomiting and fewer postoperative complications.

Consent Form

A consent form is a document with important information about a medical procedure or treatment, a clinical trial, or genetic testing. It also includes information on possible risks and benefits. If a person chooses to take part in the treatment, procedure, trial, or testing, he or she signs the form to give official consent. Any patient undergoing a surgical procedure, however minor, must sign a consent form.

Indications of Consent form
  • Avoiding Unwanted Procedures: Safeguards the patient from undergoing surgery they are unaware of or do not consent to.It protects the patient against submitting to operations that she or he does not know about or does not want. 
  • Ensures the patient understands the nature of the proposed procedure, including its risks, benefits, and potential complications, empowering them to make an informed and voluntary decision. 
  • Legal protection: Protects healthcare providers, including surgeons and hospital staff, from liability in cases where a patient or their family alleges that surgery was performed without consent.
  • Respect for Autonomy: Acknowledges and respects the patient’s right to self-determination and bodily integrity.
  • Open Dialogue: Encourages open communication between the patient and healthcare providers, allowing for any questions, concerns, or anxieties to be addressed before proceeding with the procedure.
  • Family Involvement: Facilitates the involvement of family members or loved ones in the decision-making process, particularly when the patient desires their input or support. Sometimes the patient wishes to talk to a close relative before signing the form
Factors to be considered before signing the consent form
  1. Clear Explanation: The patient must have the full explanation of the operation before signing the consent form and pictures and diagrams may be necessary.
  2. Potential Complications: The patient must be told about any possible complications and the disfigurements that may arise from the surgery.
  3. Procedure and Investigations: Explain about procedures and investigations and let him understand before accepting the operation.
  4. Anesthesia: Explain about the administration of anesthesia, addressing any concerns or questions the patient may have.
  5. Pain Management: The patient should be reassured about pain management strategies during and after the surgery.
  6. Disfigurement: If the surgery involves the possibility of disfigurement, such as amputation, mastectomy, or hysterectomy, this should be openly discussed with the patient, acknowledging the potential impact on their body image and self-esteem.
  7. Social and Economic Background: The patient’s social and economic background should be considered, understanding potential challenges or concerns related to recovery, finances, and daily life.Encourage the patient to talk about his social, economic background, and talk to him about spiritual life.
  8. Spiritual Life: The patient’s spiritual beliefs and practices should be acknowledged and addressed, offering appropriate support or resources if desired.
  9. Organ or Body Part Removal: If any organ or body part is to be removed, the patient should be informed of this in a clear and sensitive manner.
  10. Simple Explanations are given in terms that the patient can understand- the patient needs an honest and fair statement of what may be faced both in surgery and following the operation.
  11. Signature: Adults sign their consent forms unless unconscious or mentally incompetent, thus making a relative or a guardian to sign on his behalf. Children under 18 years must be signed for by an adult and preferably a relative. If a child’s parents can not be present, permission be got by telephone or letter or the surgeon may sign the form personally, depending on the laws of the state or court order may have to be obtained permitting the operation.
  12. Make sure this accompanies other medical forms to the operation room.
  13. After all the above details, a patient is asked to sign the consent form which indicates that he consents to have the operative procedure performed. This implies that he has been provided with the knowledge necessary to understand the nature of the procedure to be carried out as well as the known and possible consequences of the operation.

6. Investigations: Most of these investigations are done to make sure that the patient’s physical status is at maximum fitness and to ensure that coexisting diseases that might alter the patient’s response to surgery or his recovery are treated.

  • Routine radiographs of the chest are taken, including sputum examinations: to be sure that the patient does not have any lung problem that would complicate anesthesia or recovery after surgery, especially difficulties with inadequate oxygen supply through the lungs and cardiac function. Signs of upper respiratory infections are noted and reported.
  • Urinalysis is done: to detect urinary tract infection or any other disease that may become a serious problem especially when it comes to drug elimination after anesthesia or presence of sugar or proteins or acetone which may indicate the presence of diabetes mellitus, chronic kidney disease, starvation or dehydration respectively: for any of these may alter the treatment that is
    needed before, during and after surgery.
  • Blood tests such as, complete blood count, hemoglobin, blood grouping and cross matching bleeding and clotting time: these will help to make sure that the patient has a chronic infection, anaemia or any blood problems, which may bring problems during surgery, or interfere with wound healing and prolong a period of recovery. If Hb is low, shock may ensure intra-operatively,
    or bleeding problems may cause problems intra or post-operatively.
  • Specific investigations like ECG, Plain abdominal radiographs: are done to assess the cardiac functions so as to influence the care to be given to the patient preoperatively or for his condition to stabilize first before surgery.

7. Treatment: Antibiotics are given according to the results of the investigations and pre-existing conditions. Any other condition discovered is treated appropriately before the patient is considered ready for surgery: heart conditions, blood conditions, respiratory, urinary, digestive, etc.
8. Nutrition: The patient should be in the best possible state nutritionally before undergoing anesthesia and surgery. This is because;

  • Dehydration and poor nutrition affects the prognosis post-operatively, particularly in infants and elderly especially if caused by excessive vomiting or diarrhea and this may cause electrolyte imbalance, coupled with chronic illness and poor appetite
  • Protein deficiency leads to slow wound healing and low resistance to infection
  • Lack of vitamin C retards wound healing.
  • Interventions
  • Balanced Diet: A well-balanced diet tailored to the individual patient’s needs should be provided, including adequate protein, carbohydrates, fats, vitamins, roughages, and plenty of fluids.
  • Monitoring and Reporting: Nurses play a role in monitoring the patient’s food intake and reporting any concerns to the surgeon or dietician.
  • Individualized Approach: The patient’s likes and dislikes should be considered when planning meals to encourage food intake and ensure optimal nutrition.
  • Appropriate Feeding Routes: Feeding methods should be chosen based on the patient’s condition and needs, ensuring they receive adequate nutrition through the most appropriate route.


9. Exercises: Patients need to be instructed pre-operatively concerning the proper way to cough, deep breathe, turn and move their extremities during the postoperative period. Such instructions, given in sufficient detail and at the correct time, greatly reduce operative and post-operative complications.

  • Deep breathing exercise: this is done by inhaling slowly through the nose, distending the abdomen and exhaling slowly through the mouth, pulling the abdomen in until all air has been expelled. This should be done at least 5-10 times every hour. This is important for effective aeration of the lungs and the tissues to allow full lung expansion in thoracic surgery, to expel secretions, to prevent pneumonia and Atelectasis.
  • Coughing exercise: patient is instructed to sit or lie, take a deep breath, exhale through the mouth and then follow with a short breath while coughing from deep in the lungs. Deep breathing exercise should be done before coughing exercise to stimulate coughing reflex. Patients who will go for thoracic or abdominal surgery should be showed how to splint their incision before
    coughing in order to minimize pressure on the sutures and to control pain. A small pillow or rolled towel may be held against the incision to facilitate splinting.
  • Turning exercises: the patient will need to practice turning from side to side using the side rails if available. This prevents venous stasis and pooling of secretions in the lower lobes of the lungs, predisposing to pulmonary complications. This should be done every 1-2 hours post-operatively.
  • Extremity exercises: range of movement exercises of all the joints, flexing and extending the joints and to move each foot in a circular motion. These help to prevent circulatory problems, such as deep venous thrombosis, prevent muscle wasting and disuse, and encourage wound healing due to sufficient blood supply.

10. Treatment of existing abnormalities/infections: Abnormalities that have been detected are treated according to the diagnostic findings, e.g. mouth infections, dental caries, skin lesions, constipation, respiratory and cardiac conditions. Antibiotics, fluids, blood transfusions, painkillers are given as per the patient’s condition.
11. Hygiene: Hygiene ensures cleanliness of the skin, nails, umbilicus in case of abdominal surgery, oral care since this is the entrance to the respiratory system and digestive. It is aimed at minimizing the number of microbes that will be carried into the deeper tissues from the skin when the surgeon makes the incision. Patient’s gowns, bed linen, utensils and equipment of care are made clean including the tables, bed, etc.
12. Pre-operative visits: Visits from theater nurses and team are important to know the patient, and what he knows about the operation, to tell him the approximate length of surgery, to tell him what he will see , hear, and smell before he goes to sleep and what to expect in the recovery room.
13. Rest and sleep: Physical exhaustion deteriorates the general health and hinders many body activities and mental exhaustion aggravates shock. Patients may not relax due to fear of the forthcoming operation.

  • Prepare a comfortable freshly made bed and in a well-ventilated room.
  • Nurse avoids talking to a tired patient.
  • Visitors are restricted from always disturbing the patient.
  • Noise of any kind is avoided, i.e., using rubber-soled shoes, talking loudly is not allowed, radio sounds put at low tones, banging doors and using trolleys that make a lot of noise are avoided.
  • Sedation may be necessary to induce sleep or to reduce the pain that may interfere with sleep,

Preparation of the patient on the eve of surgery (12 hours to operation)

Skin care of the area to be operated: The skin site preparation preoperatively is aimed at removing dirt, oils and microorganisms, to prevent the growth of microorganisms that remained and to leave the skin undamaged with no
irritation from the cleansing and shaving procedure, and the area depends on the type of surgery to be done.

Principles of skin preparation
  1. The areas to be prepared should always be larger and wider and longer than the area of the proposed incision, because the surgeon may unexpectedly widen or extend the incision line.
  2. First wash the area with soap and water and start shaving when you are sure of the cleanliness.
  3. Use a strong, light, well-focused and sterile safety razor or blade.
  4. Shave against the direction of the hair shaft to ensure clean, close shave.
  5. Check the skin for nicks, irritations, and cuts since these are all potential sites for infection.
  6. Use skin antiseptics after shaving to clean the site, like chlorhexidine, iodine and others.

Specific preoperative preparations;

1. Abdominal operation: The patient’s gastrointestinal tract needs special preparation on the evening before surgery in order to reduce the possibility of vomiting and aspiration during anesthesia and to prevent contamination from fecal material during bowel surgery. The measures taken are:

  • restriction of foods and fluids to prevent vomiting during surgery, the aspiration of any vomitus and the resultant development of aspiration pneumonia. Solid food must be withheld 7-10 hours before operation, most patients receive nothing by mouth (NPO) after midnight; tea, water may be given up to 4 hours before surgery. When the surgery is scheduled until late afternoon, the patient may eat a light breakfast in the morning. When the patient is on NPO, the nurse should tell the patient not to eat and why; removes food and water from the patient’s bedside; places NPO-sign on the door and gives the report to the incoming nursing staff; extremely malnourished and debilitated patients are given intravenous infusions of glucose, amino acids or plasma up to the moment of surgery.
  • two or three enemas may be given in the evening to prevent contamination of the peritoneal cavity from the spillage of fecal content during surgery; in some cases, laxatives are given 2-3 days pre-operatively; nasogastric tubes for suction, drainage may be inserted in the evening or morning of surgery in order to remove gastric and intestinal contents; flatus tubes may as well be inserted to relieve gaseous distension; 
  • catheterization is done to drain urine and to relieve urine retention postoperatively and intra-operatively to prevent accidental injury to the urinary bladder if it is full with urine during abdominal surgery.

2. Genito-urinary system: The renal functions are often impaired by diseases of the kidneys, prostate, urethra, bladder or ureter. The patient should be instructed to take plenty of oral fluids at least 2 liters per day and the fluid balance chart be strictly charted; an indwelling catheter be inserted for continuous bladder irrigation, washout , drainage post-operatively; intravenous fluids be run to irrigate the bladder so as to avoid urine stasis which predispose to calculi formation and bladder wall infection; urine sample
is removed aseptically for urinalysis; patient is encouraged to pass urine frequently and any abnormalities are treated appropriately.

3. Rectal operation/haemorrhoidectomy: This requires special preparations because it is not easy to render the rectum a sterile or aseptic and it is also difficult to control the passage of stool. The bowel may be emptied by an aperient’s administration given in the evening before operation and also repeated in the morning and 8 hours before operation. Simple enema of soap and water is given followed by washing of the rectum and shaving the perineum.

4. Gynaecological surgery: All patients going for this operation should have antiseptic douche done and no spirit or ether are applied on the genital mucosa. Urinary catheter is passed in situ before surgery and should continue post-operatively.

5. Respiratory operation: All patients for respiratory need close respiratory observations and any respiratory infections should be treated before surgery and respiratory exercises are taught preoperatively.
Paired organs: The affected organ of the pair like the eye, ear, limb, breast, should be marked with a tag or an adhesive tape to prevent the removal of the normal side.

On the morning of surgery the nurse usually awakens the patient about an hour before preoperative medications are scheduled. During that hour, the nurse does the following tasks:

  • She records the patient’s vital signs as baseline for future observations and comparison, to detect abnormalities which may entail postponement of operation, e.g., pyrexia, tachycardia (120b/m over), or bradycardia (pulse rate below 60 b/m), urine results and weight for future comparison and for drug calculation.
  • She checks for the skin preparation if done well or there is need to be repeated in a thorough manner.
  • She asks the patient to void before going to theater to avoid bladder injury in the lower abdominal and pelvic surgery, incontinence during operation (due to anesthesia), restlessness during the early post-operative period, or if the catheter is in situ, the output is emptied and
    recorded.
  • She carries out special orders like giving enemas, insertion of catheters if not done in the evening, NGT, putting infusion lines if not done before and hanging fluids prescribed before anesthesia (1 liter of normal saline), or checking if the line is patent and the surrounding tissues are not infiltrated.
  • She gives the patient oral hygiene and removes any dentures and safely keeps them.
  • She gathers all the necessary documents like form 5, admission and observation charts, laboratory forms, x-ray radiographs, consent form, fluid balance chart, etc, and puts them together ready for theater.
  • She checks if the consent form is signed for and helps the patient if not done.
  • In privacy, she asks the patient to remove his or her own personal clothing which are safely to be kept, she removes and keeps the patient’s jewelry, earrings, but the wedding ring is usually left insitu and strapped with an adhesive tape; necklaces, bangles, plastic rings or rubber are too removed and kept together with other things.
  • She dresses the patient in a theatre gown which is clean and perhaps supports stockings. If the patient has long hair, braid them into 2 braids, all hair pins are removed to prevent scalp injury during and after surgery, and the head is covered with a protective cap.
  • Colored nail polish is removed with the nail file to help in easy assessment of cyanosis from the nail bed. Anything that is difficult to remove can be strapped off.
  • She questions the patient to make sure that food has not been eaten for the last 8 hours, or fluids taken during the preceding 4 hours, and report immediately if the patient has eaten so that surgery is postponed.
  • She makes the patient’s identification band containing his name, age ward, type of surgery to be undertaken and attaches it to the patient. She makes sure the information is accurate.
  • She gives preoperative medications: this is usually a combination of sedatives and analgesics opiates, e.g., morphine 10-15mg, or pethidine 50-100mgs, temazepam 10-20mg, tranquilizers such as diazepam 5-10mgs. These drugs are meant to reduce apprehension so as to reduce shock, to ensure sleep, and to reduce the amount of anesthetic drugs to be used, and to create amnesia for the events that precede surgery
  • Other drugs sometimes may be prescribed to be given before the patient is transported to theatre, such as antibiotics like Metronidazole i.v, + ampicillin gentamicin or chloramphenicol in some abdominal conditions, gynaecological conditions, head injury, gun shot wounds, etc. give according to the prescription.
  • Anti-secretions like atropine 0.6-1 mg is given to dry up secretions or to prevent overproduction when inhalation anesthetics are used especially ether; it improves the heart action and suppresses vagal influence on the heart. These drugs must be given half to 45 minutes preoperatively to ensure the above effects. The time of administration should be recorded accurately. If omitted or delayed, the anesthetist should be informed. Do not give under the
    maxim “better late than never”.
  • When all the preparations are ready, and the time of surgery has come, the patient is transported to the operating theater on a couch, rolled by 2 nurses. Minimal noise should be made as hearing is very acute after pre-medications. All movements to theater should be gentle, steady and unhurried. The nurse should carry all documents to the theater with the patient.
  • A full report is given to the theater nurse, or anesthetist concerning the patient.
  • A post-operative bed is then made with clean linen. The specific bed depends on the type of surgery, e.g., divided bed, fracture bed with traction appliances, etc. bedside accessories like bed cradles, infusion stands, vital observations tray, mouth care tray, infusion trays, oxygen apparatus and cylinder, suction apparatus and suction machines, bed elevators, mosquito nets, etc. this are
    the items necessary for resuscitation immediately post-operatively. The bed should be warm, without overheating to prevent shock.

Intra-operative Nursing Care

  1. Observing a client undergoing surgery may be a component of a nursing student’s experience.
    Doing so will not only give the student a better idea of surgical procedures, but it will also help in understanding the client’s feelings and apprehensions. Special training mostly given in OR technique and anesthesia Nurses assist surgeons in the operating room.
  2. The two basic categories of assistant are the sterile assistant and the circulating assistant. The sterile assistant (scrub nurse) is scrubbed, gowned and gloved. He/she functions within the sterile field. Duties include handling instruments to the surgeon, threading needles, cutting sutures, assisting with retraction and suction, and handling specimens.
  3.  The circulating nurse works outside the sterile field. Duties include opening sterile packs, delivering supplies and instruments to the sterile team, delivering medications to sterile nurse, labeling specimens, and keeping records during the surgical procedure. This person acts as a client advocate by monitoring the situation and maintaining safety in the operating room. In most
    cases, the circulating nurse must be a registered nurse.

Care of The Patients ears

EAR IRRIGATION

Ear irrigation is the process of flushing the external ear canal with sterile water or sterile saline.

Ear irrigation is a procedure where a warm, gentle stream of water is used to flush out debris, wax, or other foreign objects from the ear canal. It is the washing of the external auditory canal with a stream of fluid.

Ear syringing, also known as ear lavage, is a similar procedure but uses a larger volume of water and a more forceful stream, delivered through a syringe.

Aims /Purposes of Ear Irrigation

  • Remove earwax: This is the most common reason for ear irrigation. Accumulated earwax can block the ear canal, leading to hearing loss, discomfort, or even infection.
  • Remove foreign objects: Small objects, such as insects or seeds, can become lodged in the ear canal and need to be removed.
  • Cleanse the ear canal: Irrigation can help to remove dirt, debris, or other substances that may be present in the ear canal.
Indications for Ear Irrigation:

Indications for Ear Irrigation:

  1. Earwax impaction: To soften and remove impacted cerumen.
  2. Foreign body in the ear: Dislodge a foreign body (except hygroscopic substances like ethanol, sodium chloride).
  3. Otitis externa (swimmer’s ear): To cleanse the ear canal and remove debris that may be contributing to this infection.
  4. Chronic otitis media with effusion (glue ear): To cleanse the ear in case of purulent discharge caused by middle ear infection.
  5. Preparation for ear surgery: To cleanse the ear canal before certain ear surgeries.
  6. Prior to hearing tests: To improve the accuracy of hearing tests by removing debris that may interfere with sound transmission.
  7. Removal of ear mold impressions: To remove a mold impression from the ear canal after an ear impression is taken for hearing aids or other devices.
  8. Relief of ear pressure: To relieve ear pressure caused by changes in altitude or air pressure.
  9. To relieve localized inflammation and discomfort: Can be used to reduce inflammation and discomfort in the ear canal.
  10. For antiseptic effect: Can be used to deliver antiseptic solutions to the ear canal.
  11. To apply heat or cold: Can be used to apply warm or cold water to the ear canal for therapeutic purposes.
  12. To evaluate vestibular functions (e.g. bi-thermal caloric test): Used to assess the function of the balance system in the inner ear.

Contraindications of Ear Irrigation

  1. Perforated Eardrum: A perforated eardrum (a hole in the eardrum) allows water to enter the middle ear, which can lead to infection. Irrigation could further damage the eardrum and worsen the situation.
  2. Active Ear Infection: An ear infection, especially if it’s acute or severe, can make the ear canal more sensitive and prone to irritation. Irrigation could worsen pain, inflammation, and potentially spread the infection.
  3. Recent Ear Surgery: The ear canal needs time to heal after surgery. Irrigation could disturb the healing process and potentially lead to complications.
  4. History of Ear Surgery: Depending on the type of surgery, irrigation may not be safe. For example, if a ventilation tube has been inserted, irrigation could push the tube out of place.
  5. Excessive Pain or Discomfort: If ear irrigation causes significant pain or discomfort, it should be stopped immediately. This could indicate a problem with the ear canal or a more serious condition.
  6. Certain Medical Conditions: Conditions like diabetes, immune system disorders, or certain skin conditions could make the ear canal more susceptible to infection after irrigation.

Procedure for ear irrigation

  • Explain the procedure to the patient to obtain consent and cooperation
  • Provide privacy by screening or closing nearby windows.
  • Wash hands,
  • Prepare the equipment and bring at bedside.
  • Position the patient in sitting up.

Steps

Action

Rationale

1.

Follow general rules of nursing procedures.

 

2.

Inspect the auditory canal using the otoscope under good light.

 

3.

Ask the patient to sit and tilt the head slightly toward the affected ear. Place the mackintosh and towel over the shoulder and upper arm, under the affected ear. Place the curved part of the receiver below the tilted ear.

 

4.

Request the patient to support the receiver under the ear.

 

5.

Clean the auricle and meatus of the auditory canal with cotton wool swabs moistened with the solution.

 

6.

Fill the bulb syringe with irrigating solution. If an irrigating container is used, allow air to escape from tubing.

Air forced into the ear canal is noisy and therefore unpleasant for the patient.

7.

Straighten the auditory canal by pulling the auricle down and back for the child and up and back for an adult.

To straighten the auditory canal so that the solution can flow the entire length of the canal.

8.

Insert the tip of the syringe gently; direct a steady slow stream of solution against the roof of the auditory canal, using sufficient force to remove the secretions.

Gentleness aids in preventing injury to the tympanic membrane. Continuous in and out flow of the irrigating solution prevents pressure in the canal.

9.

Observe the patient throughout syringing.

To detect complications and be ready to act.

10.

When the irrigation is completed, place a cotton ball loosely in the auditory meatus and request the patient to lie on the affected ear on a towel or absorbent pad.

Cotton ball absorbs fluid while gravity allows remaining fluid in the canal to escape from the ear.

11.

Dry the patient’s auricle and remove the patient’s towel and mackintosh cape.

 

12.

Wash hands.

 

13.

Document the procedure, appearance of discharge and patient’s response.

 

14.

Clear away.

 

15.

Decontaminate items used in the procedure.

 

16.

Return in 10 to 15 minutes and remove the cotton ball and review the patient.

To detect pain that may indicate injury to the tympanic.

Ophthalmology

Ophthalmology is a branch of medicine that deals with the diagnosis and treatment of diseases and disorders related to the eyes. 

Definition of Terms

  1. Ophthalmologist: A medical or osteopathic doctor specializing in eye and vision care. Ophthalmologists diagnose and treat all eye diseases, perform eye surgery, and prescribe and fit eyeglasses and contact lenses to correct vision problems. Many ophthalmologists are also involved in scientific research on the causes and cures for eye diseases and vision disorders.
  2. Optometrist: A healthcare professional providing primary vision care ranging from sight testing and correction to the diagnosis, treatment, and management of vision changes. An optometrist is not a medical doctor.
  3. Optician: A technician trained to design, verify, and fit eyeglass lenses and frames, contact lenses, and other devices to correct eyesight.
  4. Ophthalmic Nurse: A nursing professional focused on assessing and treating patients with various eye diseases and injuries.

Role of Ophthalmic Nurses

  1. Provide first aid treatment in cases of eye injuries and emergencies.
  2. Perform preliminary physical examinations, such as blood tests, to detect possible underlying illnesses that could contribute to eye problems (e.g., hypertension).
  3. Conduct initial screenings on patients.
  4. Collect medical histories.
  5. Assist in eye examinations.
  6. Offer tips and advice to help patients manage eye pain and other symptoms.
  7. Demonstrate how to administer medication.
  8. Educate patients on the treatment of ocular conditions.
  9. Prepare patients for surgery and assist during operations.
  10. Provide after-surgery care for patients.
  11. Conduct various eye tests and procedures.

Ophthalmic Emergencies and Urgent Cases

Ophthalmic Emergencies and Urgent Cases

Emergencies requiring immediate medical attention include:

Sudden vision loss:

  • Central retinal artery occlusion: Blockage of the artery supplying the central retina.
  • Central retinal vein occlusion: Blockage of the vein draining blood from the retina.
  • Giant cell arteritis: Inflammation of the arteries in the head, including those supplying the eye.
  • Retinal detachment: Separation of the retina from the back of the eye, especially if the macula (central part of the retina) is still attached.

Primary acute glaucoma: Rapid increase in pressure within the eye, causing pain, blurred vision, and halos around lights.

Trauma:

  • Penetrating or perforating injuries: Objects entering the eye.
  • Chemical burns: Exposure of the eye to chemicals.

Orbital cellulitis: Infection of the tissues surrounding the eye.

Urgent cases requiring prompt medical attention, but not considered true emergencies:

  • Corneal ulcer: Open sore on the cornea, causing pain, redness, and blurred vision.
  • Vitreous hemorrhage: Bleeding into the vitreous humor (jelly-like substance filling the back of the eye), causing blurred vision or floaters.
  • Acute dacryocystitis: Inflammation of the lacrimal sac (tear sac), causing pain, swelling, and redness.
  • Optic nerve disorders: Conditions affecting the optic nerve, causing vision loss or other visual disturbances.
  • Ocular tumors: Growths within the eye, which may affect vision or require treatment.
  • Acute uveitis: Inflammation of the middle layer of the eye, causing pain, redness, and blurred vision.

EYE CARE

Eye care is characterized as the special attention given to the eyes to prevent complications.

Natural Cleansing: The production of tears and the blinking mechanism provide a natural cleansing process for the eyes (Harrison, 2006). When this process is interrupted, the eyes may need to be artificially cleansed to remove debris, prevent dryness, and ensure eyelid closure (Dawson, 2005).

Eye Cleansing: Eye cleansing can be performed alone or with eye swabbing, instilling eye medication, and applying eye padding/dressing/shield.

Indications for Eye Care:

  • Children Undergoing Eye Surgery: Pre-operative and post-operative eye care is important to ensure the eye is clean, free from infection, and well-prepared for surgery. This care includes instilling prescribed eye drops, maintaining proper hygiene, and following specific instructions from the ophthalmologist.
  • Children Whose Eyes Cannot Close Properly: Hydrocephalus, cerebral palsy, facial nerve palsy, and other conditions affecting eyelid closure,, where eyelid function may be compromised, maintaining eye moisture and cleanliness is essential to prevent corneal damage and infection.
  • Unconscious, Sedated, or Muscle-Relaxed Children: These children cannot blink or close their eyes effectively, making them prone to dryness and exposure to keratitis. Regular eye care, including lubrication and protective measures, is necessary to prevent complications.
  • Presence of Infection (e.g., Conjunctivitis/Neonatal Conjunctivitis): Eye infections require careful cleansing and medication administration to control and eradicate the infection. This prevents the spread of infection and promotes faster healing.
  • Infants with Non-Infected Sticky Eye Due to Underlying Causes (e.g., Blocked Tear Ducts): Conditions like blocked tear ducts can cause sticky discharge. Regular eye cleaning helps keep the eye clear and reduces the risk of secondary infections.
  • Immunosuppressed Children: These children are more susceptible to infections due to their weakened immune systems. Regular and prompt eye care helps prevent opportunistic infections and maintain eye health.
  • Trauma: Eye injuries require prompt and careful cleaning to remove debris, prevent infection, and manage pain. Eye care post-trauma is crucial for recovery and to avoid further damage.
  • Chronic Eye Conditions (e.g.,Dry Eye Syndrome): Conditions causing chronic dryness need regular lubrication to maintain comfort and prevent damage to the cornea and conjunctiva.
  • Post-Chemotherapy/Radiation Therapy: Children undergoing cancer treatments may experience eye issues due to the side effects of therapy. Regular eye care can mitigate symptoms like dryness and irritation.
  • Congenital Eye Disorders (e.g., Ptosis, Congenital Glaucoma): Children with congenital eye disorders may need regular eye care to manage symptoms, prevent complications, and support overall eye health.
  • Post-Cataract Surgery: After cataract surgery, careful eye care is necessary to ensure proper healing, prevent infection, and manage any postoperative complications.
  • Severe Allergies: Children with severe allergies may experience frequent eye irritation and discharge, necessitating regular cleaning and medication application.
  • Exposure to Environmental Irritants: Children exposed to smoke, dust, or chemicals need regular eye cleaning to remove irritants and prevent damage.

Purpose of Performing Eye Care:

  • Maintain Eye Cleanliness: Regular eye care helps keep the eyes clean, promoting comfort for the patient and reducing the risk of cross-infection, particularly in clinical settings.
  • Prevent Eye Dryness: Various methods are employed to keep the eyes moist and comfortable. These include:

  • Methylcellulose Drops: Used for general lubrication.

  • Ointments: Provide longer-lasting moisture.

  • General Lubricants: Help maintain moisture balance.

  • Polyacrylamide Hydrogel Dressings: Effective for unconscious, sedated, or paralyzed children as they moisten and lubricate the eye area while maintaining eyelid closure.

  • Hypromellose Drops (Artificial Tears): Used to supplement natural tears and prevent dryness.

  • Ensure Eyelid Closure: Using polyacrylamide hydrogel dressings like Geliperm® helps keep the eyelids closed, which is crucial for preventing exposure to keratitis in patients who cannot close their eyes naturally.
  • Treat Existing Eye Infections: Proper eye care is essential for treating infections, involving cleaning the eye and administering appropriate medications to eradicate the infection and prevent its spread.
  • Prepare for Medication Administration: Ensuring the eye is clean and free from debris before administering medications enhances the effectiveness of the treatment and reduces the risk of complications.
  • Protect the Eye During Phototherapy: When using phototherapy light lamps, especially in newborns with jaundice, eye care measures are taken to protect the retina from potential damage caused by the light exposure.
  • Support Healing Post-Surgery: After eye surgeries such as cataract removal, meticulous eye care supports the healing process, reduces the risk of infection, and helps manage post-operative discomfort.
  • Manage Allergic Reactions: In cases of severe allergies, eye care involves cleaning and administering anti-allergy medications to reduce irritation and prevent secondary infections.
  • Facilitate Proper Drainage: For conditions like blocked tear ducts, regular eye care helps in facilitating drainage and reducing discomfort and infection risk.
  • Prevent Damage in Systemic Conditions: In children with systemic conditions like diabetes, regular eye care is vital to monitor and manage potential complications, thus preserving eye health.
  • Educate Caregivers: Eye care is a tool for educating caregivers on proper eye care techniques, signs of complications, and the importance of maintaining eye hygiene ensures consistent and effective care for the child.

Purpose of Eye Medications:

Topical medication is the preferred route for treating eye diseases. Eye medications are delivered to:

  • Treat infections.
  • Provide intraocular treatment for diseases such as glaucoma.
  • Prepare for and recover from surgical procedures.
  • Dilate pupils for eye examinations and/or refraction.
  • Provide lubrication.

Care of the Child Undergoing Eye Surgery:

The care involves pre-operative, intra-operative, and post-operative care.

Pre-operative Care:

Common conditions requiring surgical intervention include trauma, Cataracts, Foreign body eye, Congenital malformations, Glaucoma, Eye injuries, Astigmatism or strabismus, Sagging of the upper eyelid (ptosis) and detached retina. The ophthalmologist will determine the treatment and procedure, ranging from a simple incision to total removal of the eyeball (enucleation).

  • Admission: The child will be admitted to a warm and clean bed in the pediatric surgical ward. The bed will have enough light to ensure a comfortable environment for the child and will be free from environmental dust to minimize the risk of infection.
  • History taking: Take a detailed history of the child’s medical background, including any previous surgeries, allergies, or medical conditions, also inquire about any medications the child is currently taking.
  • Physical examination. A thorough physical examination will be conducted and will assess the child’s overall health and identify any potential risks or concerns. The physical examination will include checking vital signs such as heart rate, blood pressure, and temperature and the child’s eyes will be examined to evaluate the specific condition requiring surgery and to ensure there are no additional eye health issues.
  • Observation: Vital signs (temperature, respiration, pulse, blood pressure). Observation of the affected eye.
  • Investigations: History taking from the child and parent, Physical examination of the eye, tests like Visual acuity test, Visual field test and Tonometry test for fluid pressure inside the eye (evaluates for glaucoma) are ordered and done.
  • Physical Orientation: Thorough orientation to the hospital environment to help the patient post-operatively, especially if vision is impaired. Assist older children to learn details of their room (location of furniture, doors, windows, etc.). Familiarize the patient with voices and daily sounds.
  • Education: Thorough education about post-operative care and restrictions. Keep the head still, avoid reading, showers, shampooing, tub baths, bending over, lifting heavy objects, and sleeping on the operative side.
  • Explaining the Diagnosis and the Need for Surgery: Communicate with the patient, explaining the diagnosis and the reasons for the recommended surgery. This helps the patient understand the importance of the procedure and alleviates any concerns or fears they may have.
  • Reassurance and Counseling: It is important to provide emotional support and reassurance to the patient, addressing any anxieties or fears they may have about the upcoming surgery. Counseling may also be provided to help the patient cope with the stress associated with the procedure.
  • Booking and Scheduling the Operation: The date and time for the surgery are scheduled, taking into account the patient’s availability and the surgical team’s availability. In some cases, surgeries may be booked several months in advance, and the patient should be informed about what to do in case of any problems or changes before the scheduled date.
  • One Week Before Surgery: Preoperative tests and assessments may be conducted, such as blood tests, imaging studies, and specific examinations related to the surgical procedure. The patient may also be instructed to take certain medications or eye drops as prescribed.
  • A Day Before Surgery: In some cases, the patient may be required to be temporarily admitted to the hospital the day before the surgery. During this time, the patient’s feeding and hygiene needs are addressed, and a detailed history and physical examination, including ophthalmological tests, are performed. The patient is also informed about the personal requirements and procedure-related instructions.
  • Day of Operation: The patient is required to sign a consent form, indicating their agreement for the operation. Depending on the anesthesiologist’s instructions, the patient may need to be nil per os (NPO), refraining from eating or drinking for at least 8 hours prior to surgery. Reassurance, hygiene measures, removal of jewelry, and administration of pre-medication, if necessary, are also carried out. Hydration may be provided as instructed.
  • Rest and Sleep: Ensure rest and minimize noise and bright light.
  • Physical Preparation:

    • Bowel Prep: Bowel preparation is sometimes required before surgery to empty the bowels and prevent straining post-operation. This may involve taking a laxative or using an enema the evening before surgery.

    • Hair Removal: Hair removal, such as shaving of eyebrows, cutting of eyelashes, and shaving of the face, should only be done on the surgeon’s order. In some cases, hair removal may be necessary to ensure a sterile surgical field. 

    • Postoperative Bed Preparation: Depending on the type of surgery, it may be necessary to prepare a postoperative bed with side rails and sandbags for head immobilization. This is done to ensure the patient’s safety and prevent any accidental movement or injury during the recovery period.

  • Transportation to the Operating Room: When it is time for the patient to be taken to the operating room, two nurses accompany the patient. This is done to ensure the patient’s safety and provide any necessary support during the transportation process.
post operative care after eye surgery
Post-operative Care:
  • When the nurses arrive at the theater to pick up the child after surgery, the first step is to check the child’s vital signs and obtain a detailed report from the theater staff who performed the surgery. This ensures continuity of care and that all necessary information is communicated effectively.
  • The patient is taken to the pediatric surgical ward in a post-operative bed, positioning the child face down as ordered by the surgeon. This specific positioning is important for optimal recovery and to prevent complications.

Upon arrival at the pediatric surgical ward, the following post-operative care procedures are implemented:

Initial Care and Positioning.

  • Vital Observations: Regular monitoring of vital signs, including heart rate, blood pressure, respiratory rate, and oxygen saturation.
  • Positioning: The child is positioned in bed as prescribed, usually face down to ensure recovery and prevent complications.
  • Immobilization: If ordered, sandbags may be used to immobilize the head to prevent any unnecessary movement that could affect healing.
  • Safety Measures: If both eyes are bandaged, the side rails of the bed are kept raised to prevent falls. The call bell is placed within easy reach of the patient’s head for safety and communication.
  • Rest and sleep: The child is allowed to rest in the ward temporarily to recover from the effects of anesthesia. The bed positioning continues to be monitored to ensure it aligns with the surgeon’s instructions.

Ongoing Observations:

  • Bleeding: Continuous monitoring for any signs of bleeding from the surgical site.
  • Dressings: Regular checks to ensure dressings are secure and dry. Any signs of infection or complications are promptly addressed.

Welcoming the Child:

  1. The child is gently welcomed back to the ward and from the effects of anesthesia. Comforting words and reassurance are provided to help ease any anxiety or discomfort they may feel upon waking.
  2. Apply non-sterile gloves (to remove old eye dressing or patches/shields and discard them appropriately. If eye dressings  are difficult to remove from the eyelid / lashes, apply gauze moistened with 0.9%w/v NaCl solution to the eye dressing.
  3. Assess the general condition of each eye and surrounding tissue before proceeding for:-
  • Redness
  • Swelling
  • Abrasions
  • Irritation (itching, stinging, burning)
  • Discharge (colour, odour, volume)
  • Eyelid position (partial/full closure, blink)
  • If cooperative, ask the child to look upwards, or if uncooperative gently hold the child with parental assistance and then gently pull the lower lid downwards to part the eyelid.
  • If there is evidence of any encrustation on the eyelids and lashes, dampen sterile gauze with 0.9%w/v NaCl solution and apply to the eye.
  • If there is any discharge, perform an eye swab before proceeding with eye cleansing

Performing Eye Swabbing:

  • Use a sterile cotton wool swab to roll over the conjunctival sac inside the lower eyelid.
  • Place the swab in the transport medium and transport immediately to the laboratory.
  • For suspected Chlamydia Infection, perform the eye swab after eye cleansing.

Performing Eye Cleansing:

  • Use 0.9% NaCl or sterile water in a sterile gallipot.
  • Moisten sterile gauze with the solution.
  • Wipe the eye from the inside aspect to the outside aspect, using a new gauze square for each stroke.
  • Clean the non-infected eye first.
  • Decontaminate hands again.

Instilling Eye Medication:

  • Cleanse the eye(s) before instilling medication.
  • Check the child’s identification band against the medication prescription chart.
  • Adolescents over 16 may consent to the procedure, but supervision is required if the medication affects vision.
  • Use new medication containers post-surgery.
  • Position a hand gently on the forehead while holding the medication container.
  • Place a tissue/non-sterile gauze swab under the lower eyelid and gently pull down the lower eyelid.

Applying Eye Padding/Dressing(s)/Shields:

  • Eye Padding: Apply gauze over the closed eyelid and secure it with tape.
  • Eye Dressings: Use polyacrylamide hydrogel dressings (Geliperm®) to cover the closed eyelid.
  • Eye Shield: Apply a clear shield over the affected eye and secure it with clear tape.

Precautions:

  • Secure eye dressings with an eye shield or reinforce loose tape.
  • Restrain the arms of children and disoriented patients as appropriate.
  • Constantly watch sleeping patients to maintain proper positioning.
  • Avoid jarring the bed to prevent startling the patient.
  • Monitor for depression or suicidal tendencies in newly blinded patients.
  • Check the physician’s orders before giving anything by mouth to avoid nausea and vomiting.

Approaching the Patient:

  • Always speak to the patient upon entering their area and before touching them.
  • Explain each procedure or activity fully.
  • Reinforce orientation to surroundings.
  • Inform the patient when leaving their area.

Diversional Activity:

  • Provide non-fatiguing activities if eyes are not bandaged.
  • Encourage visitors to chat or read to the patient.
  • Use a radio for entertainment and to keep the patient informed.

Nursing Care of the Patient with Vision Loss:

  • Physical Orientation: Describe the room and its contents in detail and lead the patient around the room.
  • Precautions: Inform the patient about any changes in the room, keep doors fully open or closed, maintain the placement of toilet articles, and remove hazardous items.
  • Assisting the Patient: Address the patient by name, inform them when leaving, and allow them to place their hand on your arm or shoulder when walking.
  • Encourage Independence: Encourage the patient to be self-sufficient.
Complications of eye surgery;
  • Infections such as Endophthalmitis: A serious infection inside the eye. This can lead to vision loss if not treated promptly.
  • Fluid and Swelling like Cystoid Macular Edema: Swelling and fluid build-up in the macula, the central part of the retina responsible for sharp, central vision. This can cause blurred vision.
  • Corneal Edema: Swelling of the cornea, the clear outer layer of the eye. This can cause blurry vision and discomfort.
  • Bleeding (Hyphema): Bleeding in the front chamber of the eye, the space between the cornea and the iris. This can cause pain, redness, and blurry vision.
  • Tissue Damage such as Capsule Rupture: The capsule surrounding the lens may rupture during surgery, leading to loss of vitreous gel, the clear jelly-like substance that fills the eye. This can cause blurry vision and other complications.
  • Retinal Detachment: The retina, the light-sensitive tissue at the back of the eye, can become detached from the underlying choroid. This can lead to permanent vision loss.
  • Cataract Formation: While rare, eye surgery can sometimes trigger the development of a new cataract.
  • Glaucoma: Eye surgery can, in some cases, increase the pressure inside the eye, potentially leading to glaucoma.
  • Dry Eye Disease: Dry eye can become worse or develop after eye surgery due to changes in the eye’s surface.
Care at Home After Eye Surgery

Bathing

  • Clean your eyelid edges: At least twice a day with a moist, clean face cloth, avoiding pressure on the upper eyelid.
  • Showering/Bathing: You may shower or take a tub bath and wash your hair the day after surgery.
  • Avoiding Soap/Water in Eye: Ensure no soap or water enters the eye for at least one week.
  • Eye Make-up: Do not wear eye make-up for at least one week.
  • Avoid Fibrous Materials: Do not use cotton balls or make-up remover pads near your eye or under the eye shield.

Care of Your Eye

Responsibility of nurse during ophthalmology

Responsibility of nurse during ophthalmology

The Nurse’s Role in Ophthalmic Visual Acuity Testing

Visual acuity, the measurement of central vision sharpness, is a cornerstone of any ophthalmic examination. An accurate assessment is important  for diagnosis and treatment planning. It tests the entire visual system, from the occipital cortex (brain) to the cornea (front of the eye).

Nurses responsibilities include;

1. Preparing the Patient:

  • Explaining the Test: Clearly explain the purpose of the test and how it’s conducted, ensuring the patient understands the process.
  • Addressing Concerns: Answer any questions the patient may have regarding the test.
  • Ensuring Comfort: Make the patient feel comfortable and relaxed. Offer assistance with positioning and support.
  • Assessing Language Barriers: Identify and address any language barriers to ensure comprehension.

2. Performing the Test:

  • Using the Appropriate Chart: Select the appropriate visual acuity chart based on the patient’s age, literacy, and any specific needs (e.g., Snellen chart for adults, LEA chart for children).
  • Maintaining Proper Distance: Ensure the patient is positioned at the correct distance from the chart (typically 20 feet or 6 meters).
  • Occluding the Non-Tested Eye: Properly cover the non-tested eye to avoid cross-viewing.
  • Recording Results: Accurately document the visual acuity reading for each eye, including the distance from the chart and the line identified.

3. Identifying Factors that May Affect Acuity:

  • Refractive Error: Assess for signs of refractive errors (nearsightedness, farsightedness, astigmatism) that could impact visual acuity.
  • Media Opacity: Observe any cloudiness in the ocular media (cornea, lens, vitreous) that may interfere with light transmission and affect acuity.
  • Patient Cooperation: Recognize and document any lack of patient cooperation or comprehension that could affect the accuracy of the test.

4. Reporting Observations:

  • Communicating with the Ophthalmologist: Communicate any relevant observations, including patient cooperation, suspected refractive errors, or signs of media opacity to the ophthalmologist for further assessment and diagnosis.
Factors Influencing Accurate Visual Acuity Testing:
  • Patient Cooperation: The patient must understand and follow instructions, including focusing on the chart and maintaining a fixed gaze.
  • Recognition of Forms: The patient needs to be able to identify the forms displayed on the chart.
  • Ocular Media Clarity: The cornea, lens, and vitreous must be clear for light to pass through and reach the retina.
  • Focusing Ability: The eye must be able to focus properly on the chart.
  • Eye Convergence: Both eyes need to work together to converge on the target.
  • Retinal Function: The retina must be able to receive and process the visual information.
  • Intact Visual Pathways: The optic nerve and brain pathways must be intact for visual information to travel to the brain.

Common charts used in the measurement of distance visual acuity

The most common chart for measuring distance visual acuity in a literate adult is the Snellen chart. Distance vision is tested at 6 meters, as rays of light from this distance are nearly parallel. If the patient wears glasses constantly, vision may be recorded with and without glasses, but this must be noted on the record. Each eye is tested and recorded separately, the other being covered with a card held by the examiner.

Snellen’s Chart

Heavy block letters, numbers, or symbols printed in black on a white background are arranged on a chart in nine rows of graded size, diminishing from the top downwards. The top letter can be read by the normal eye at a distance of 60 meters, and the following rows should be read at 36, 24, 18, 12, 9, 6, 5, and 4 meters, respectively.

snellen's chart

Procedure:

  • One eye is tested at a time, with the other eye covered.
  • The patient reads lines of letters, starting from the top and working down.
  • The smallest line the patient can read correctly indicates their visual acuity.

Recording: Visual acuity is recorded as a fraction (e.g., 20/20, 6/6), where the numerator represents the distance at which the patient can read the line and the denominator represents the distance at which a person with normal vision can read that same line.

Using the pinhole in the measurement of visual acuity

Occasionally, a patient’s visual acuity may be below average, which could be a result of a refractive error not corrected by glasses, or due to the patient wearing an old pair of prescription glasses. One effective, but very simple, way to see if distance visual acuity can be improved through spectacles or a change of prescription is a pinhole. A pinhole disc only allows central rays of light to fall onto the macula and does not need to be refracted by the cornea or lens. A ‘pinhole disc’ is used if the VA is less than 6/6 or 6/9, which may improve VA. If a considerable increase in vision is obtained, it may usually be assumed that there is no gross abnormality, but rather a refractive error.

Using the pinhole in the measurement of visual acuity

  1. Purpose: Used when visual acuity is below average, to determine if the problem is refractive error (uncorrected by glasses) or another condition.
  2. Method: A pinhole disc restricts light to pass through a small opening, improving focus and reducing blur caused by refractive errors.
  3. Interpretation:
  • If visual acuity significantly improves with the pinhole, it suggests a refractive error.
  • If visual acuity does not improve, it may indicate another underlying eye condition.

 

Sheridan Gardner Test Chart

The Sheridan Gardner test chart can be used for children and patients who are illiterate. This test type has a single reversible letter on each line. For example, A, V, N. The child holds the card with these letters printed on and is asked to point to the letter on his card which corresponds to the letter on the test type. This test can also be used for very young children as they do not have to name a letter.

Sheridan Gardner Test Chart

Procedure:

  1. The patient holds a card with the same letters printed on it.
  2. The examiner points to a letter on the chart.
  3. The patient points to the corresponding letter on their card.

Kay Picture Chart

The Kay picture chart is again used with patients who are illiterate or with children. Instead of letters, the book contains pictures, which are also of varying sizes. The patient is asked what the picture represents. In order to avoid any misunderstanding amongst patients with language difficulties, it is good practice to ask the hospital’s official interpreter to translate for patients.

Kay Picture Chart

Tumbling E chart

The tumbling E chart is mainly used for patients who are illiterate. In the chart, the Es face in different directions. The patient is asked to hold a wooden E in his hand and to turn it the same way as the one the examiner is pointing to on the test chart.

tumbling E chart

Procedure:

  • The patient holds a wooden “E”.
  • The examiner points to an “E” on the chart.
  • The patient rotates their wooden “E” to match the orientation of the “E” on the chart.

Prepare For Neural Assessment

NEUROLOGICAL EXAMINATION

Neurological examination is a type of patient  assessment which aims at detecting the functions of the cranial nerves in relation to the five senses.

What is a neurological exam?

A neurological exam, also called a neuro exam, is an evaluation of a person’s nervous system.

This examination aims to detect abnormalities in cranial nerve function, which are responsible for controlling the body’s five primary senses:

  • Sight (Vision) – Assessed through eye movement, visual fields, and pupillary reflex.
  • Hearing (Audition) – Tested using tuning forks or audiometry to determine sound perception.
  • Smell (Olfaction) – Evaluated by identifying different scents to assess olfactory nerve function.
  • Taste (Gustation) – Checked by applying various taste stimuli to different parts of the tongue.
  • Touch (Somatosensation) – Includes tests for pain, temperature, vibration, and proprioception.

It is also an evaluation of a person’s nervous system. The nervous system consists of the brain, the spinal cord, and the nerves from these areas. 

Key Components of a Neurological Exam

There are many aspects of this exam, including an assessment of motor and sensory skills, balance and coordination, mental status (the patient’s level of awareness and interaction with the environment), reflexes, and functioning of the nerves.

  1. Mental Status Examination: Evaluates cognition, memory, orientation, and language skills. Includes tests such as recalling words, following commands, and responding to questions.
  2. Cranial Nerve Assessment: Examines the twelve cranial nerves, responsible for functions like facial movement, swallowing, and vision.
  3. Motor Function and Muscle Strength: Tests muscle tone, strength, and involuntary movements. Evaluates for conditions like paralysis, muscle atrophy, or tremors.
  4. Reflexes: Assesses deep tendon reflexes (e.g., knee-jerk reflex), Babinski reflex, and other involuntary responses. Used to detect spinal cord or nerve root damage.
  5. Coordination and Balance: Includes tests such as the finger-to-nose test, heel-to-shin test, and Romberg test. Assesses cerebellar function and motor control.
  6. Gait Analysis (Walking Assessment): Observes walking patterns, step length, and postural stability. Used to detect conditions like Parkinson’s disease, ataxia, or nerve damage.
  7. Sensory Function Evaluation: Checks the ability to feel pain, temperature, vibration, and proprioception. Helps diagnose neuropathies, spinal cord disorders, or stroke-related sensory loss.

Indications for a Neurological Exam

A complete neurological exam may be performed in the following situations:

Routine Physical Exam: As part of a general health assessment, especially in older adults or individuals with risk factors for neurological disorders.

Post-Trauma: Following any head, neck, or back injury, regardless of severity, to rule out potential neurological damage.

Disease Progression Monitoring: To track the progression of known neurological conditions such as multiple sclerosis, Parkinson’s disease, or dementia. It helps in adjusting treatment plans and assessing the effectiveness of interventions.

Specific Neurological Complaints: When a patient presents with any of the following symptoms:

  • Headaches: Especially new-onset, severe, persistent, or accompanied by other neurological symptoms.
  • Visual Disturbances: Including blurry vision, double vision, loss of vision, or visual field defects.
  • Behavioral or Cognitive Changes: Such as memory loss, confusion, personality changes, or difficulty with language.
  • Unexplained Fatigue: Persistent and excessive tiredness that interferes with daily activities.
  • Balance or Coordination Problems: Including dizziness, vertigo, unsteadiness, or difficulty with fine motor skills.
  • Sensory Abnormalities: Numbness, tingling, burning, or pain in the limbs or other parts of the body.
  • Motor Weakness: Reduced strength or difficulty moving limbs, facial muscles, or other body parts.
  • Involuntary Movements: Tremors, tics, spasms, or other abnormal movements.
  • Seizures: Any type of seizure activity, including new-onset seizures or changes in seizure patterns.
  • Speech Difficulties: Slurred speech, difficulty finding words, or problems with comprehension.
  • Back Pain: particularly when associated with weakness, numbness, or bowel or bladder dysfunction.

Altered Mental Status: To evaluate changes in alertness, orientation, or level of consciousness. This includes:

  • Assessment of Consciousness: Evaluating levels of alertness, responsiveness, and orientation in patients with altered mental status.

Sensory Evaluation: Detailed assessment to evaluate:

  • Paresthesia: To determine the location, severity, and nature of abnormal sensations.

Cranial Nerve Assessment: To evaluate:

  • Cranial Nerve Function: Systematic testing of each of the twelve cranial nerves to identify deficits.

Important Points to Note:

When performing the exam, ensure that substances used to assess taste, smell, touch, or feeling are not visible to the patient. This prevents the patient from identifying the substance by sight, which could lead to inaccurate results.

 

Equipment for the Procedure:

  • Ophthalmoscope or Torch: To assess pupil dilation and constriction (eye reaction).
  • Snellen Chart: For visual acuity testing.
  • Otoscope: For ear examination.
  • Tuning Fork: To evaluate hearing.
  • Pins or Needles: For testing sense of touch (e.g., pain or sensation loss).
  • Cotton Wool (in a gallipot): For tactile sensation.
  • Hot/Cold Water Bottle: To assess the sense of touch and taste.
  • Salt and Sugar Bottles: For taste assessment.
  • Coffee or Lemon Bottle: For smell testing.
  • Nasal Speculum: For nasal inspection.
  • Tape Measure: To measure areas with sensory loss.

Components of a Neurological Exam

The neurological exam typically includes the following assessments:

Mental Status:

  1. Level of Awareness: Assessed through conversation to determine the patient’s awareness of person, place, and time.
  2. Attentiveness: Evaluate whether the patient stays focused or requires frequent redirection.
  3. Orientation: Check orientation to self, place, and time. Disorientation to time typically occurs before place or person, and disorientation to self often indicates a psychiatric issue.
  4. Speech and Language: Assess fluency, repetition, comprehension, reading, writing, and naming.
  5. Memory: Evaluate both registration and retention capabilities.
  6. Higher Intellectual Function: Assess general knowledge, abstraction, judgment, insight, and reasoning abilities.
  7. Mood and Affect: Evaluate mood and emotional expression, primarily to determine if psychiatric conditions are affecting the neurological assessment.

cranial nerves

Evaluation of the cranial nerves:

There are 12 cranial nerves. During a complete neurological exam, most of these nerves are evaluated to help determine the functioning of the brain:

  1.  Cranial nerve I (olfactory nerve): This is the nerve of smell. The patient may be asked to identify different smells with his or her eyes closed.
  2.  Cranial nerve II (optic nerve): This nerve carries vision to the brain. A visual test may be given and the patient’s eye may be examined with a special light.
  3.  Cranial nerve III (oculomotor): This nerve is responsible for pupil size and certain movements of the eye. The patient’s healthcare provider may examine the pupil (the black part of the eye) with a light and have the patient follow the light in various directions.
  4.  Cranial nerve IV (trochlear nerve): This nerve also helps with the movement of the eyes.
  5.  Cranial nerve V (trigeminal nerve): This nerve allows for many functions, including the ability to feel the face, inside the mouth, and move the muscles involved with chewing. The patient’s healthcare provider may touch the face at different areas and watch the patient as he or she bites down.
  6.  Cranial nerve VI (abducens nerve): This nerve helps with the movement of the eyes. The patient may be asked to follow a light or finger to move the eyes.
  7.  Cranial nerve VII (facial nerve): This nerve is responsible for various functions, including the movement of the face muscle and taste. The patient may be asked to identify different tastes
    (sweet, sour, bitter), asked to smile, move the cheeks, or show the teeth.
  8.  Cranial nerve VIII (acoustic nerve): This nerve is the nerve of hearing. A hearing test may be performed on the patient.
  9.  Cranial nerve IX (glossopharyngeal nerve): This nerve is involved with taste and swallowing. Once again, the patient may be asked to identify different tastes on the back of the tongue. The gag reflex may be tested.
  10.  Cranial nerve X (vagus nerve): This nerve is mainly responsible for the ability to swallow, the gag reflex, some taste, and part of speech. The patient may be asked to swallow and a tongue blade may be used to elicit the gag response.
  11. Cranial nerve XI (accessory nerve): This nerve is involved in the movement of the shoulders and neck. The patient may be asked to turn his or her head from side to side against mild resistance, or to shrug the shoulders.
  12.  Cranial nerve XII (hypoglossal nerve): The final cranial nerve is mainly responsible for movement of the tongue. The patient may be instructed to stick out his or her tongue and speak.

perform colostomy care

Perform Colostomy Care

Colostomy Care

Colostomy is the surgical procedure of  creating of an opening (ie. Stoma) into the colon intestine through the abdominal wall.

A colostomy is an operation that redirects the colon from its normal route, down toward the anus, to a new opening in the abdominal wall. The opening is called a stoma.

An ileostomy is a surgical procedure that brings a portion of the small intestine (the ileum) to the surface of the abdomen, creating an opening called a stoma. This opening allows stool to exit the body directly, bypassing the colon entirely.

Feature

Ileostomy

Colostomy

Intestinal Segment

Ileum (small intestine)

Colon (large intestine)

Stool Consistency

Liquid or semi-liquid

Can range from liquid to formed

Frequency

Frequent (multiple times a day)

Less frequent than ileostomy

Odor

Stronger odor

Generally less strong than ileostomy

Control

Limited control over bowel movements

More potential for control over bowel movements

Reasons

Ulcerative colitis, Crohn’s disease, colon cancer, etc.

Similar reasons to ileostomy, but also for conditions specific to the colon

Purpose of colostomy care 

It allows for drainage or evacuation of colon contents to the outside of the body.

Needs for the colostomy care:

  • Maintain Stoma and Peristomal Skin Integrity: This includes protecting the stoma from trauma, irritation, and infection, as well as maintaining the health of the skin surrounding the stoma.
  • Prevent Skin Breakdown: This includes minimizing the risk of lesions, ulcerations, excoriation, and other skin issues caused by fecal contaminants.
  • Prevent Infection: Colostomy care should prioritize preventing bacterial and fungal infections that can occur due to exposure to fecal matter.
  • Promote General Comfort: This includes minimizing discomfort, irritation, and odor associated with the colostomy.
  • Enhance Self-Image and Self-Concept: Colostomy care should consider the psychological impact of living with a colostomy and aim to promote a positive self-image and body image.
  • Ensure Effective Fecal Evacuation: This includes using appropriate pouching systems that effectively collect and contain fecal matter.
  • Reduce Odor: Colostomy care should involve strategies to minimize unpleasant odors, such as regular pouch changes, odor neutralizers, and proper hygiene practices.

Indications of Colostomy

  1. Tumors of the Colon: This includes both benign and malignant tumors that require surgical intervention.
  2. Trauma and Perforation of the Colon: Severe injuries to the colon can necessitate a colostomy to allow for healing and prevent infection.
  3. Inflammatory Diseases of the Colon: Conditions like ulcerative colitis, Crohn’s disease, and diverticulitis may require a colostomy to manage inflammation, reduce symptoms, and allow for healing.
  4. Congenital Anomalies of the Gastrointestinal Tract (GIT):
  • Hirschsprung’s Disease: This congenital condition causes a lack of nerve cells in the colon, leading to constipation and fecal retention.
  • Necrotizing Enterocolitis: This serious condition, primarily seen in premature infants, involves inflammation and death of the bowel.
  • Imperforate Anus: This condition occurs when the anus is absent or blocked, requiring surgical intervention.
  • Other Anomalies: Other congenital malformations of the colon, such as anorectal malformations, may require a colostomy.
colostomy types

Type of colostomy:

By  Location

  1. Ascending Colostomy: Located in the ascending colon, on the right side of the abdomen. It produces more frequent, liquid stools.
  2. Transverse Colostomy: Located in the transverse colon, across the abdomen. Stools are usually semi-solid and less frequent.
  3. Descending Colostomy: Located in the descending colon, on the left side of the abdomen. Stools are usually formed and more consistent.
  4. Sigmoid Colostomy: Located in the sigmoid colon, in the lower left abdomen. Stools are generally formed and can sometimes be controlled by regulating bowel movements.

By Duration:

  • Permanent Colostomy: This type of colostomy is intended to be long-term or lifelong. It’s usually performed when the original colon has been removed or severely damaged.
  • Temporary Colostomy: This type of colostomy is intended to be temporary, used to allow a portion of the colon to heal or to divert stool flow while other surgeries are performed.

By colostomy operation.

  • Loop Colostomy: This type involves creating a loop of the colon that is brought to the surface of the abdomen. The loop is divided by a bridge of tissue, with one opening for stool and the other for mucous discharge. A loop colostomy is often the method of choice when a colostomy is meant to be temporary because it’s easier to reverse.
  • End Colostomy: This type involves bringing the end of the colon to the surface of the abdomen, creating a single opening for stool. An end colostomy is often done when the colostomy is expected to be permanent. In this procedure, after your bowel is cut, the end of the remaining active bowel is stitched to the opening in your abdominal wall, and the end of the remaining inactive bowel is sealed.
  • Double-Barrel Colostomy: This type involves bringing both ends of the colon to the surface of the abdomen, creating two separate openings.

Nursing Diagnosis:

1. Comfort Alteration related to abdominal incision evidenced by:

  • Reports of pain at the incision site.
  • Grimacing or guarding behavior.
  • Elevated pain scores on a pain scale.
  • Difficulty with movement or ambulation.
  • Restlessness or anxiety related to pain.

2. Impaired Skin Integrity related to the presence of stoma evidenced by:

  • Presence of redness, swelling, or irritation around the stoma.
  • Skin breakdown, such as abrasions, fissures, or ulcers.
  • Reports of discomfort or itching around the stoma.
  • Leakage or drainage from the stoma.

3. Body Image Disturbance related to the presence of stoma evidenced by:

  • Expressing negative feelings or self-consciousness about the stoma.
  • Avoiding social situations or activities.
  • Difficulty looking at or touching the stoma.
  • Statements about feeling unattractive or different.

4. Knowledge Deficit related to stoma care and lack of experience evidenced by:

  • Asking numerous questions about stoma care.
  • Demonstrating incorrect stoma care techniques.
  • Expressing anxiety or fear about managing the stoma.
  • Lack of confidence in performing self-care activities.

Nurses Consideration

Assessment of the Stoma

  • The stoma should be pink. A dusky blue stoma indicates ischemia, and a brown-black stoma indicates necrosis.
  • Assessment of stoma color should be done every 8 hours.
  • There is mild to moderate swelling of the stoma in the first 2-3 weeks after surgery. This could be due to trauma to the stoma or any medical condition that results in edema. Severe edema could be due to obstruction of the stoma, allergic reaction to food, or gastroenteritis.
  • Small oozing/bleeding from the stoma mucosa when touched is normal because of its high vascularity. Moderate to large amounts of bleeding from the stoma could indicate coagulation factor deficiency, lower gastrointestinal bleeding, etc.

Protecting the Skin

  • The skin should be washed with mild soap, rinsed with warm water, and dried thoroughly before the skin barrier is applied.
  • Skin barriers include petroleum jelly gauze or protective ointment smeared around the stoma to keep the skin from becoming irritated. Hollister skin or stoma adhesive barriers are applied. However, the ointment must be removed at frequent intervals to ascertain that the skin under the protective coating remains in good condition.
  • The patient is provided with dressing items for changing the dressings and colostomy. A dressing tray is needed for this.

Clothing

  • Immediately after surgery, many patients choose to wear loosely fitting clothes.
  • Clients should not wear a leather belt over the stoma to avoid irritation.
  • All pouching systems are waterproof, so clients can bathe, shower, and swim while wearing them.
  • Clients can remove soiled pouches and shower without them but not with an ileostomy because bowel function with an ileostomy is fairly frequent and unpredictable.

Activity

  • Heavy lifting is prohibited for 6-8 weeks after abdominal surgery to prevent hernia, which can occur in the incision and around the stoma.

Diet

  • Clients should follow a low-fiber diet for approximately 1 month. After one month, a person with a colostomy can follow a regular diet.
  • Ileostomy diet should be closely monitored. Foods that cause blockage, such as popcorn, many vegetables, nuts, and meat, should be avoided.

Client and Family Teaching

  • The medical team assists the client and family with various aspects of ostomy care.

Health Education

The patient should be able to do the following before being discharged:

  • Change the colostomy bag: apply and change the pouch to collect intestinal drainage and empty it when it is 1/3 full to prevent leakage.
  • Care for the skin, control odor, maintain general hygiene, care for the stoma, and identify signs of complications. They should be able to cleanse the skin and use skin barriers and deodorants to prevent skin breakdown and bad odor.
  • Understand the importance of fluids and food in the diet: identify a well-balanced diet and dietary supplements to prevent nutritional deficiencies, identify foods that reduce diarrhea, gas, or obstruction, drink at least 3 liters per day to prevent dehydration unless contraindicated, and increase fluid intake during hot weather, excessive sweating, and diarrhea to replace losses.
  • Know how to get additional supplies—addresses of supply departments.
  • Understand the importance of follow-up care: report signs and symptoms of fluid and electrolyte deficits, fever, diarrhea, skin irritation, other stoma problems such as changes in appearance or function, changes in the peristomal area, tenderness, redness, and pain.

Selecting the Pouch

  • The colostomy bag should be transparent, plastic, odor-proof, cut large enough to envelop the stoma, and fit snugly to prevent fecal contents from getting onto the skin and staining the patient’s gown or bed linen. It should have a valve for drainage of the content or be changed whenever it is full if it does not have this provision.
  • The pouch should not be placed directly on the skin without the skin barrier.
  • The volume, color, and consistency of the drainage are recorded each time the bag is changed, and the condition of the skin is observed for irritation. The content of the ascending and transverse colon is liquid in nature, while that from the descending and sigmoid colon is semi-formed or formed.
  • The patient should be observed for fluid and electrolyte imbalance if large volumes of drainage are present. In the case of an ileostomy, in the first 24-48 hours post-operatively, there will be a high volume output of 1000-1800 ml/day, but it should reduce to 800ml daily.
  • Encourage the patient to take 2-3 liters of fluids daily and more if diarrhea is present.

Colostomy Irrigation

  • This is intended to regulate bowel function and treat constipation. It is a small enema done through the stoma using lukewarm water (500-1000ml), but a soft large bore catheter is used to avoid bowel perforation. Do not force the tube if there is resistance to Tubal entry.

Feeding after Colostomy and Control of Smell

  • The diet should be of low-roughage initially and then reintroduced later gradually. Seeds should be chewed properly, and hard ones avoided to prevent small bowel obstruction.
  • Foods that cause smell should be avoided, e.g., eggs, onions, fish, cabbage, alcohol, etc.
  • Gas-forming foods should be avoided or eaten in moderation, e.g., beans, onions, cabbage, potatoes, beer, carbonated beverages, etc.
  • Diarrhea-causing foods such as alcohol, spinach, green beans, coffee, spicy foods, and raw fruits should be avoided.
  • A regular diet is encouraged later on, and a normal one is very important as long as the above is put into consideration.

Assisting the Patient to Adapt Psychologically to a Changed Body and Sexual Activity

  • Stress the need for the patient to care for the colostomy but do not force them until they show readiness to do so.
  • Every effort should be made to keep the patient as clean and dry as possible, as they may become depressed at the sight of fecal drainage, particularly if it is so liquid and soils the bed linen and gown.
  • Soiled linen should be disposed of neatly and quickly.
  • Reassure the patient that fear of continuous drainage should not keep them from moving about freely.
  • The social impact of the stoma is interrelated with the psychological, physical, and sexual aspects.
  • Concerns of people with stomas include the ability to resume sexual activity, altering clothing styles, the effect on daily activities, sleeping while wearing a pouch, passing gas, presence of odor, cleanliness, and deciding when or if to tell others about the stoma. The fear of rejection from a partner or the fear that others will not find them desirable as a sexual partner can be a concern. The nurse should encourage open communication about feelings and realize that the patient needs time to adjust to the pouch and body changes before feeling secure in their sexual functioning.
  • Pregnancy is possible with a colostomy, but the number of pregnancies needs to be limited.

Nursing Care Guidelines

General Care

  • Be gentle yet professional: Approach all aspects of ostomy care with empathy and professionalism to ensure patient comfort and trust.
  • Observe stoma condition: Regularly inspect the stoma for any changes in color, size, or appearance.
  • Maintain cleanliness: Change any appliances, dressings, or linens that become soiled to prevent infection.
  • Check for undissolved medications: When changing an ileostomy appliance, inspect for any undissolved tablets or capsules that may indicate absorption issues.
  • Provide special skin care: Protect the skin around the stoma with appropriate barriers and treatments to prevent irritation and infection.
  • Clean with care: Once the stoma is healed, clean it with mild soap and water. Avoid using alcohol, and discontinue soap if it causes irritation. If redness or yeast-like growth appears, consult a healthcare provider.
  • Encourage independence: Teach the patient how to remove and apply new appliances, and what to monitor and report regarding bowel changes.
  • Support emotional health: Allow the patient to express their feelings, encourage questions, and address any misconceptions they may have.

Abnormal and Danger Signs in a Stoma

  • Abnormal sounds: Unusual noises from the stoma may indicate issues.
  • Excessive bleeding: Any significant bleeding should be reported immediately.
  • Color changes: Darkening of the stoma can indicate stenosis and compromised blood supply. Bleaching or extreme lightening suggests a lack of circulation.
  • Drying of the stoma: The stoma should remain moist; drying may indicate problems.
  • Signs of infection: Look for redness, swelling, or discharge.
  • Edema of the stoma: Swelling could indicate an obstruction or other complications.

Routine Observations

  • Appliance size: Ensure the appliance fits correctly—not too tight to cut off circulation, but snug enough to prevent leakage.
  • Daily weight: Monitor the patient’s weight daily to assess for any significant changes that could indicate fluid or nutritional imbalances.
  • Electrolyte balance: Regularly check blood work results to monitor for any imbalances.
  • Stool assessment: Record the amount and character of stool to identify any changes or issues.
  • Vital signs: Regularly monitor vital signs to detect any early signs of complications.
COMPLICATIONS OF COLOSTOMY

Complications of Colostomy

1. Surgical Complications:

  • Wound Infection: Bacteria can enter the surgical wound, causing inflammation, pain, and potential delay in healing.
  • Hemorrhage: Bleeding from the surgical site can occur, requiring prompt medical attention.
  • Parastomal Hernia: A bulge of abdominal contents through the weakened abdominal wall around the stoma.

2. Stoma-Related Complications:

  • Stenosis: Narrowing of the stoma, leading to difficulty passing stool and potential blockage.
  • Prolapse: The stoma protrudes outwards from the abdomen, potentially causing discomfort and interfering with pouch adherence.
  • Retraction: The stoma can retract or shrink, making it challenging to attach the colostomy bag securely.
  • Necrosis: Death of stoma tissue, usually due to insufficient blood supply, requiring emergency surgery.

3. Skin Issues:

  • Skin Irritation and Breakdown: Prolonged exposure to fecal matter can lead to skin irritation, inflammation, and ulceration around the stoma.
  • Infection: Infection can occur in and around the stoma, leading to discomfort and complications.

4. Bleeding and Obstruction:

  • Bleeding: Some bleeding from the stoma is normal, but excessive bleeding can indicate issues such as infection or trauma.
  • Obstruction: Blockages can occur in the colostomy, preventing the passage of stool and leading to discomfort and potential complications.

5. Fluid and Electrolyte Imbalance:

  • Dehydration: Patients with a colostomy are at risk for dehydration because they lose fluids and electrolytes through the stoma.
  • Electrolyte Imbalance: Patients with a colostomy may also experience an electrolyte imbalance, which can occur when they lose too many electrolytes through the stoma.

6. Psychosocial and Nutritional Issues:

  • Psychosocial Issues: Patients may experience body image disturbances, depression, or anxiety related to the presence of a colostomy.
  • Nutritional Deficiencies: Patients with a colostomy may also experience nutritional deficiencies because they may not be able to absorb nutrients properly.

carry-out-gastric-lavage

Carry Out Gastric Lavage

Carry Out Gastric Lavage

Gastric lavage is the process of cleaning out stomach contents.

Gastric lavage is a gastrointestinal decontamination technique that aims to empty the stomach of toxic substances by the sequential administration and aspiration of small volumes of fluid via a nasogastric tube or stomach tube.

Gastric lavage is the process of washing out of the stomach via a nasogastric tube or  stomach tube.
Lavage is ordered to wash out the stomach (after ingestion of poison or an overdose of medication, for example) or to control gastrointestinal bleeding. If the patient does not have a nasogastric tube in place already, the physician will order the insertion of the appropriate tube.

Indications for Gastric Lavage:

  1. Ingestion of toxic substances: Gastric lavage is indicated when a patient has swallowed anything unwanted or poisonous. It is a method to remove toxic substances from the stomach before they are absorbed into the systemic circulation.
  2. Pre-endoscopic procedure: Gastric lavage can be performed to clear the contents of the stomach before an upper endoscopic procedure. This helps to improve visualization during the procedure.
  3. Collection of stomach acids for testing: Gastric lavage can be used to collect stomach acids for diagnostic testing.
  4. Relief of gastric pressure: Gastric lavage can be used to relieve pressure in the stomach in cases where there is a blockage in the stomach or nearby areas like the intestine. This can help alleviate symptoms and prevent complications.
  5. Collection of sputum in children: Gastric lavage is useful in collecting sputum samples from children who cannot produce it. It is a preferred procedure for children suspected of having pulmonary tuberculosis.
  6. Cooling technique in hyperthermic patients: Gastric lavage can be used as a cooling technique in hyperthermic patients. By irrigating the stomach with cool fluids, it helps to lower the body temperature.
  7. Diagnostic tool for gastric hemorrhage: Gastric lavage can be used to diagnose inflammatory conditions like gastric hemorrhage. Through examining the lavage fluid about the presence and severity of bleeding.
  8. Poisoning cases: Gastric lavage is commonly performed in cases of poisoning, especially when it is life-threatening or when the patient’s history is not available. It can help remove toxic substances from the stomach and reduce the absorption of the poison. 
  9. Ingestion of substances: Also used incases of;
  • Ingestion of potentially life threatening substances e.g. chloroquine, cyclic antidepressants e.g. amitriptyline, imipramine.
  • Ingestion of large amounts of a substance not absorbed to charcoal e.g. iron, lithium.
  • Ingestion of substance which have propensity to form bezoars (a mass found trapped in the GIT) e.g. iron salicylates such as aspirin, acetylsalicylic acid

Contraindications of Gastric Lavage:

  • Comatose and convulsing patients: Gastric lavage should not be performed on patients who are comatose or experiencing seizures.
  • Ingestion of a corrosive substance: Gastric lavage is contraindicated in cases where the ingested substance is a strong acid or strong alkaline, as it can cause further damage to the esophagus and stomach.
  • Pills too large for lavage tube: If the pills or tablets ingested are too large to pass through the lavage tube, gastric lavage should not be performed.
  • Patients at risk of hemorrhage or gastrointestinal perforation: Individuals who have a pre-existing condition that puts them at risk of bleeding or gastrointestinal perforation should not undergo gastric lavage.
  • Ingestion of hydrocarbons and detergent: Gastric lavage is contraindicated in cases of ingestion of substances such as ethanol (a hydrocarbon) and detergent.
  • The poison ingestion is not toxic at any dose: If the ingested poison is not toxic at any dose, gastric lavage is not necessary.
  • The poison ingestion is adsorbed by charcoal and adsorption is not exceeded by the quantity ingested: If activated charcoal can effectively adsorb the poison and the quantity ingested does not exceed the adsorption capacity, gastric lavage may not be required.
  • Presentation many hours after poisoning: If the patient presents several hours after the poisoning incident, gastric lavage may not be beneficial.
  • A highly efficient antidote is available: If there is a highly efficient antidote available for the ingested poison, gastric lavage may not be necessary.

Complications of Gastric Lavage:

  • Increase gastric delivery of tablets into the small bowel: Gastric lavage can potentially push tablets or pills further into the small bowel, increasing their absorption .
  • Aspiration of gastric contents: There is a risk of aspiration, where the gastric contents can enter the lungs, leading to respiratory complications. This occurs in approximately 3% of patients undergoing gastric lavage .
  • Esophageal rupture: Although rare, there is a risk of esophageal rupture during the lavage procedure .
  • Cardiac complications: In certain poisonings, such as those involving propranolol or calcium channel blockers, gastric lavage can precipitate extreme bradycardia, cardiac arrest, and asystole due to the effects on cardiac conduction .
  • Nasal trauma: Insertion of the lavage tube can cause nasal trauma.
  • Tracheal intubation: In cases where the airway is unprotected, tracheal intubation may be required before performing gastric lavage.
  • Electrolyte imbalance and hypothermia: The administration of large volumes of fluid during gastric lavage can potentially lead to electrolyte imbalances and hypothermia.

  • Collect the equipment needed and prepare the trolley

  • Explain the procedure to the patient.

  • Screen the bed and close the adjacent windows 

  • Bring the trolley to the bedside 



To enable cooperativeness.

To ensure privacy.

To prevent unnecessary movement.

2.

Place a bucket on the floor at the bedside.

To collect wastes.

3.

Request the patient to sit up if conscious. If unconscious, put the patient in a prone position and place a mackintosh cape and towel around the patient’s neck and bed clothes.

To protect the bed and patient.

4.

Connect up the funnel to the tubing using a connector but keep the stomach tube separate until it has been passed.

To prevent aspiration of the fluid by the patient.

5.

Lubricate the tube and pass it over the tongue into the pharynx and esophagus.

To ease passage of the tube.

6.

Keep on asking and encouraging the patient to swallow.

To gain patient’s cooperation.

7.

Connect the syringe on the tube and withdraw some stomach content.

To ensure that the tube is in the stomach.

8.

Test the stomach content with a litmus paper to confirm that you are in the stomach.

Acidic stomach content will turn blue litmus paper red.

9.

Clip the stomach tube with an artery forceps and place it in the receiver.

To prevent backflow of stomach contents.

10.

Apply a clip to the funnel and tubing then attach it to the stomach tube.

To prevent the flow of fluids before starting the procedure.

11.

Open the clip and allow approximately 300 mls of fluid to run into the lower funnel until level begins to rise; 


invert the funnel into the bucket to siphon out the stomach contents. Repeat the procedure until the fluid which is returning is clear. Note the nature of the stomach contents.

To empty the stomach of unwanted or harmful contents.

12.

Clip the stomach tube, withdraw it from the stomach evenly and quickly, disconnect the tube from the funnel and tubing and place it in the receiver.

To prevent trauma to the patient.

13.

Give the patient a mouthwash, thank him and clear away the requirements.

To encourage patient’s comfort.

14.

Wash your hands and document the findings.

(a). Type and amount of lavage solution used.

(b). Appearance, odor, color, and amount of gastric return.

(c). Patient’s tolerance to procedure.

(d). Disposition of specimens.

Clear away all the requirements.
