Symptom Control & GIT Symptoms
INTRODUCTION

Palliative care patients often experience multiple, overlapping symptoms. Unlike curative care — where we treat one disease — in palliative care, we must assess and manage many symptoms at once, while also supporting the patient emotionally, spiritually, and socially.

💡 Key Idea: Holistic Comfort
Good symptom control doesn't just make the patient comfortable — it restores dignity, reduces family distress, and can even prolong meaningful life. A patient free from agonizing pain or constant nausea can actually eat, interact with family, and find peace.
PRINCIPLES OF SYMPTOM ASSESSMENT

Before you give any medication or intervention, you must assess thoroughly. Think of assessment as the foundation of a house — if the foundation is weak, everything else collapses.

The Golden Rules of Assessment
Principle What It Means Why It Matters (Clinical Rationale)
Accept the patient's description If the patient says "my pain is 10/10," believe them. Pain and symptoms are subjective. Only the patient knows how they truly feel. Pain is whatever the experiencing person says it is.
Assess each symptom separately A patient may have pain, nausea, and anxiety all at once. Don't lump them together. Each symptom may have a completely different pathophysiological cause and need different targeted treatment.
Diagnose the cause Don't just treat the symptom — ask why it is happening. Treating vomiting with antiemetics is useless (and dangerous) if the underlying cause is a mechanical bowel obstruction.
Take a detailed history When did it start? How severe? What makes it better or worse? (PQRST method) Patterns reveal causes. Timing often points to specific drug side effects or disease progression.
Medication history What has the patient taken before? What worked? What failed? Avoids repeating failed treatments, identifies drug interactions, and prevents overdose.
Physical examination Always examine the patient, even if you think you know the diagnosis. Physical signs often reveal hidden causes that history misses (e.g., a silent, distended bladder causing extreme agitation).
Don't wait for complaints Ask proactively. Observe body language and facial expressions. Patients in some cultures may not complain openly due to stoicism or fear of being a burden.
Investigate wisely Use tests to guide care, not just to collect data. In palliative care, unnecessary tests (like daily blood draws) cause distress and delay comfort without altering the care plan.
Don't delay treatment for tests Start practical management while waiting for results. Comfort is the absolute priority. Do not let a patient suffer while waiting 24 hours for a lab result.
Explain to patient and family Tell them what you think is happening and what you plan to do. Reduces anxiety, builds deep trust, and empowers the family.
Review! Review! Review! Reassess after every intervention. Symptoms change dynamically; your treatment must adapt.

🧠 Mnemonic for Assessment: "A-S-S-E-S-S M-E"

  • Accept patient's words
  • Separate each symptom
  • Seek the cause
  • Examine physically
  • Story/history (detailed)
  • Screen for associated symptoms
  • Medication history
  • Explain and review
PRINCIPLES OF SYMPTOM MANAGEMENT

Once you've assessed, you manage. These principles guide every treatment decision in palliative care.

The Management Framework
Step Action Example
Evaluate Confirm the diagnosis/cause of the symptom. Vomiting caused by opioid-induced constipation vs. vomiting caused by bowel obstruction.
Explain Tell the patient what you're doing and why. Set realistic goals. "We will give you medicine to reduce the nausea. It may take 30 minutes to work."
Manage Give individualised treatment. No one-size-fits-all in palliative care. A frail elderly patient with poor renal function needs lower doses than a younger adult.
Monitor Check if the treatment worked. If not, adjust. Nausea still present after 1 hour? Consider adding a second antiemetic acting on a different brain receptor.
Attention to detail Don't assume. Check everything. Constipation can masquerade as diarrhoea (overflow incontinence).
Drug + non-drug Use both together for best effect. Morphine for pain + relaxation techniques + repositioning + massage.
Allow time Don't declare a treatment a failure too quickly. Some antiemetics take 30–60 minutes to work. Wait for the drug's peak onset before abandoning it.
Multidisciplinary team Involve doctors, nurses, social workers, chaplains, physiotherapists. A patient with breathlessness needs medical, nursing, and psychological/spiritual support.
Consult senior When unsure, ask a more experienced clinician. Better to ask than to harm.
Refer if needed Some symptoms need specialist input. Severe, intractable neuropathic pain may need a pain specialist or nerve block.
Treat the cause Where possible, remove the root cause. Constipation from opioids? Treat the constipation with laxatives, don't just accept it.

🧠 Mnemonic for Management: "E-M-M-A D-D-M-C-T"

  • Evaluate
  • Manage individually
  • Monitor
  • Attention to detail
  • Drug + non-drug
  • Don't rush (allow time)
  • Multidisciplinary
  • Consult senior
  • Treat the cause
SUMMARY OF KEY POINTS
  • Assessment always comes before treatment.
  • Believe the patient. Their description is your most important data.
  • Examine physically — don't rely on history alone.
  • Investigate wisely — don't do tests just for the sake of it.
  • Don't delay comfort while waiting for test results.
  • Explain everything to the patient and family.
  • Use both drug and non-drug measures.
  • Review continuously — palliative care is dynamic.
  • Work as a team — no one person can do it all.
  • Treat the cause where possible, not just the symptom.
GASTRO-INTESTINAL (GIT) SYMPTOMS

GIT symptoms are among the most distressing in palliative care. They affect nutrition, hydration, dignity, and quality of life. We will cover nausea and vomiting, diarrhoea, and constipation.

NAUSEA AND VOMITING
Understanding the Mechanism (Physiology Expansion)

To treat nausea and vomiting effectively, you must understand where the signal comes from. The brain has a vomiting centre that can be triggered from multiple pathways. (Physiological note: The choice of antiemetic is based entirely on which receptor—Dopamine, Serotonin, Histamine, or Muscarinic—is being triggered in these specific zones).

Trigger Site What It Does Example Causes
Vomiting centre (VC)
(Located deep in the medulla)
The "final common pathway" — once activated, vomiting occurs. Receives input from all other zones. Direct stimulation by drugs, toxins, or brain tumours.
Chemoreceptor trigger zone (CTZ)
(Lacks a blood-brain barrier!)
Detects toxins/drugs in the blood and tells the vomiting centre to act. (Rich in Dopamine D2 and Serotonin 5HT3 receptors). Opioids, chemotherapy, uraemia, hypercalcaemia.
Vestibular apparatus (inner ear) Detects motion and balance. (Rich in Histamine H1 and Muscarinic M1 receptors). Motion sickness, vestibular disease, opioid-induced sensitivity to movement.
Gastrointestinal tract Distension, irritation, or obstruction sends vagal nerve signals up to the brain. Gastritis, peptic ulcer, pancreatitis, bowel obstruction, severe constipation.
Cerebral cortex Psychological triggers (anxiety, anticipation, bad smells, terrifying sights). Anticipatory vomiting before chemotherapy, severe anxiety.
Think of it like this: The vomiting centre is the "boss." Different departments (CTZ, gut, inner ear, brain) can call the boss and say "we need to vomit now." Your antiemetic must target the right department's phone line.
Causes of Nausea and Vomiting in Palliative Care
  • Infections: Oesophageal candidiasis (common in HIV), cytomegalovirus.
  • Drugs: Opioids, antibiotics, ARVs, NSAIDs, chemotherapy.
  • Metabolic: Uraemia (kidney failure), hypercalcaemia, liver failure.
  • Raised intracranial pressure: Brain metastases, cerebral oedema.
  • Gastrointestinal: Gastritis, peptic ulcer, pancreatitis, bowel obstruction, constipation.
  • Psychological: Anxiety, anticipatory vomiting, depression.
  • Unrelated to primary illness: Food poisoning, gastroenteritis.

🇺🇬 Uganda Clinical: In HIV-positive palliative patients, oesophageal candidiasis is a very common cause of nausea and painful swallowing (odynophagia). Always inspect the mouth and throat using a torch/penlight!

Assessment of Nausea and Vomiting
What to Ask / Examine Why It Matters
Amount and content of vomit Coffee-ground = possible bleeding (ulcer); faeculent (looks/smells like stool) = late bowel obstruction; bile (green) = duodenal reflux.
Smell/odour Foul smell suggests severe infection, necrosis, or low obstruction.
Distinguish vomiting from regurgitation Vomiting = forceful, active contraction of diaphragm; Regurgitation = passive flow back (e.g., in oesophageal obstruction or stricture).
Duration and frequency Acute vs. chronic; pattern guides diagnosis.
Precipitating factors After eating? After medication? On movement? (Movement-induced points to vestibular issues).
Medication history Is a new drug causing this? (e.g., starting oral Morphine).
Abdominal examination Rule out pancreatitis, gastritis, peptic ulcer, obstruction (look for distension, listen for high-pitched 'tinkling' bowel sounds).
Neurological check Signs of raised intracranial pressure? (e.g., early morning vomiting without nausea, severe headache).
Pharmacological Management

The choice of antiemetic depends on the cause. Match the drug to the specific receptor pathway!

Target Pathway Drug Class Examples Dose
Vomiting centre Anticholinergics / Antihistamines Hyoscine butylbromide
Cyclizine
10 mg BD
50 mg every 6 hours
Chemoreceptor trigger zone (CTZ) Dopamine antagonists Prochlorperazine (Stemetil)
Haloperidol
5–10 mg TDS
0.5–1 mg BD
Gut motility (upper GI) Prokinetics Metoclopramide 5–10 mg TDS
Vestibular apparatus Antihistamines / Phenothiazines Cyclizine, Prochlorperazine As above
Uraemia / metabolic Dopamine antagonists Haloperidol 0.5–1 mg

⚠️ CRITICAL WARNING: METOCLOPRAMIDE
Metoclopramide is strictly contraindicated in bowel obstruction. Because it is a prokinetic, it aggressively increases peristalsis (gut squeezing). If the bowel is physically blocked by a tumor or stool, forcing it to squeeze harder against a brick wall can cause extreme pain, worsening obstruction, and catastrophic bowel perforation. Always rule out obstruction before giving metoclopramide!

Nursing Exam Tip: If a question gives you a patient with vomiting and abdominal distension, and asks which antiemetic to avoid — the answer is metoclopramide.
Non-Pharmacological Management
  • Psychological support: Anxiety worsens nausea; reassurance and explanation reduce fear.
  • Relaxation techniques: Deep breathing, guided imagery.
  • Dietary modifications: Small, frequent meals; bland foods; avoid greasy/spicy foods. Avoid serving favorite foods while severely nauseated to prevent permanent food aversions.
  • Increase fluid intake: If appropriate and not contraindicated.
  • Calm environment: Remove food smells, strong odours, and visual triggers (like vomit bowls sitting in plain sight).
  • Fresh air: Open windows or use a fan.
DIARRHOEA
Understanding Diarrhoea

Diarrhoea is defined as:

  • Acute: Less than 7–14 days.
  • Chronic: More than 2–3 weeks.

In palliative care, diarrhoea causes: Dehydration, severe electrolyte imbalance (hypokalemia), skin breakdown (perianal excoriation), and intense embarrassment leading to loss of dignity and social isolation.

Causes of Diarrhoea
  • Infection: Bacterial, viral, parasitic (highly common in HIV/AIDS).
  • Medication: Antibiotics (disrupt gut flora), too-high laxative doses, some ARVs.
  • Stress / anxiety: Psychological diarrhoea (fight-or-flight response speeds up gut).
  • Overflow diarrhoea (Paradoxical Diarrhoea): Liquid stool leaking around impacted, rock-hard faeces (looks like diarrhoea but is actually severe constipation!).
  • Malabsorption: Pancreatic insufficiency, intestinal damage (radiation enteritis).

⚠️ CRITICAL DISTINCTION: OVERFLOW DIARRHOEA
Always distinguish true diarrhoea from overflow diarrhoea. Overflow occurs when hard stool blocks the rectum, and only liquid stool higher up can squeeze past it. Treating this with anti-diarrhoeals (like Loperamide) paralyzes the gut and makes the fatal blockage worse. The treatment is disimpaction and laxatives, NOT anti-diarrhoeals.

Assessment of Diarrhoea
  • Acute or chronic? Guides urgency and likely cause.
  • Volume and frequency: Severity assessment for dehydration risk.
  • Presence of blood: Bloody diarrhoea = infection, inflammation, or bowel tumour.
  • Associated symptoms: Fever (infection), abdominal pain (colitis), weight loss (malabsorption).
  • Dietary practices: Food poisoning? Lactose intolerance?
  • Medication review: Is a drug causing this?
  • Stool tests: Culture and sensitivity if infection suspected.
Pharmacological Management of Diarrhoea
Intervention Details
Oral rehydration At least one cupful (preferably more) after each episode. Use ORS if available.
Loperamide 2–4 capsules stat, then 2 capsules after each loose motion. Do NOT use if infection or overflow suspected.
Codeine 30 mg TDS — slows gut motility (opioid effect).
Liquid morphine 5 mg/5 ml, 5 ml every 4 hours, 10 ml at night.
Antibiotics If bacterial infection confirmed (e.g., Septrin 480 mg 2 BD).
IV fluids In severe dehydration or if oral intake impossible.
Nursing Tip: Monitor for signs of dehydration — dry mucous membranes, sunken eyes, reduced skin turgor, reduced urine output (oliguria), tachycardia, hypotension.
Skin Care in Diarrhoea
  • Barrier cream: Aqueous cream or zinc oxide applied after each episode to protect skin from highly acidic stool.
  • Regular cleaning: Gentle washing with warm water, pat dry (do not aggressively rub). Prevents excoriation and infection.
  • Mackintosh / plastic under-sheet: Protects bedding, maintains dignity and comfort.
  • Frequent changing: Prevents prolonged skin contact with stool, preventing rapid pressure sore formation.
CONSTIPATION
Why Constipation is So Common in Palliative Care (Pathophysiology)

Constipation is one of the most common and most undertreated symptoms in palliative care. Why?

  • Patients are on opioids (morphine, codeine): Opioids bind to mu-receptors in the gut wall. This slows peristalsis (propulsion), increases sphincter tone, and allows the intestines to absorb too much water from the stool, turning it to stone (Opioid-Induced Bowel Dysfunction - OIBD).
  • Patients are immobile: Physical movement stimulates gravity and bowel peristalsis.
  • Patients are dehydrated: Lack of fluid results in hard stools.
  • Patients have poor nutrition: Low fibre intake means no stool bulk to trigger the urge to defecate.
  • Tumours: May physically compress and obstruct the bowel from the outside.
Assessment of Constipation
  • Previous and present bowel pattern: What is "normal" for this patient? Aim for their usual pattern.
  • History of cause: Opioids? Dehydration? Tumour?
  • Abdominal examination: Distension? Tenderness? Palpable hard faecal mass in the left lower quadrant?
  • Digital rectal examination (DRE): May be needed to assess for physical impaction in the rectum.
Nursing Tip: Don't assume a patient is constipated just because they haven't opened their bowels for 2 days. Some patients normally go every 3 days. Know their baseline!
Pharmacological & Non-Pharmacological Management
  • Bisacodyl: 5–15 mg at night (Stimulant laxative — forcefully increases gut motility).
  • Review constipating drugs: Reduce dose or switch if possible (Opioids are the main culprit, prescribe a laxative simultaneously with opioids!).
  • Rectal intervention: Enema or suppository if severely impacted.
  • High-fibre diet & Fluids: Adds bulk and softens stool.
  • Mobilise: Movement stimulates peristalsis.
  • Privacy: Anxiety about lack of privacy suppresses the urge to defecate!
  • Routine: Encourage patient to try at the same time daily (harnessing the gastrocolic reflex after meals).

🌿 Traditional Remedy: Pawpaw Seeds (Uganda)
In Uganda, where commercial laxatives may be scarce or expensive, pawpaw (papaya) seeds are an excellent, culturally appropriate traditional remedy. Chewed or crushed in fruit drink, they contain papain enzymes and fiber that act as a highly effective natural laxative.

COMPARISON TABLE: NAUSEA, DIARRHOEA, AND CONSTIPATION
Feature Nausea/Vomiting Diarrhoea Constipation
Most common cause Drugs (opioids), infections, raised ICP Infection, drugs, overflow Opioids, immobility, dehydration
Key danger Dehydration, aspiration pneumonia Dehydration, skin breakdown Overflow diarrhoea, bowel obstruction, faecal impaction
Must rule out... Bowel obstruction (before metoclopramide) Overflow (before loperamide) Overflow (may mimic diarrhoea)
First-line drug Depends heavily on cause Loperamide (if not infection/overflow) Bisacodyl
Non-drug priority Calm environment, small meals Rehydration, excellent skin care Fluids, fibre, mobilisation
Nursing red flag Coffee-ground vomit = active bleeding Blood in stool = serious pathology No bowel movement + severe abdominal distension = obstruction
EXAM TIPS AND MNEMONICS

🧠 Mnemonic for Anti-Emetics: "C-H-M-P-H"

Remember: Match the drug to the cause, not just the symptom!

  • C - Cyclizine (antihistamine) — 50 mg 6-hourly
  • H - Haloperidol (dopamine antagonist) — 0.5–1 mg
  • M - Metoclopramide (prokinetic) — 5–10 mg TDS
  • P - Prochlorperazine (phenothiazine) — 5–10 mg TDS
  • H - Hyoscine (anticholinergic) — 10 mg BD
❓ Exam-Style Application Questions

Q1: A patient on morphine for cancer pain has not opened their bowels for 5 days and now has loose, watery stool leaking from the rectum. What is the likely diagnosis, and what should you NOT give?
Answer: This is overflow diarrhoea due to severe faecal impaction. Do NOT give loperamide or other anti-diarrhoeals. The treatment is manual disimpaction and aggressive laxatives (e.g., rectal enema, bisacodyl).

Q2: A patient with advanced cancer starts vomiting after beginning morphine. Which antiemetic would you choose, and why?
Answer: Morphine triggers nausea by acting directly on the Chemoreceptor Trigger Zone (CTZ) in the brain. You must choose a drug that blocks the CTZ. Haloperidol (0.5–1 mg) or Prochlorperazine are the correct choices.

Q3: Why is metoclopramide extremely dangerous in bowel obstruction?
Answer: Metoclopramide is a prokinetic — it forcefully increases gut peristalsis. In a mechanical obstruction, this increases pressure proximal to the blockage and can cause a fatal bowel perforation.

Q4: A patient with HIV and oesophageal candidiasis is nauseated and unable to swallow. What non-pharmacological measures can the nurse implement?
Answer: Small frequent meals of bland food, maintaining a calm environment away from triggering food smells, psychological reassurance, and positioning upright for at least 30 minutes after eating.

SUMMARY: KEY NURSING POINTS FOR GIT SYMPTOMS
  • Nausea and vomiting: Match the antiemetic strictly to the physiological cause (vomiting centre, CTZ, gut, vestibular, cortex).
  • Never give metoclopramide if bowel obstruction is possible.
  • Diarrhoea: Always distinguish true diarrhoea from overflow diarrhoea (constipation in disguise).
  • Rehydration is critical in diarrhoea — oral rehydration first, IV if severe.
  • Skin care is essential in diarrhoea — use barrier creams, regular cleaning, and protect bedding.
  • Constipation is the most common GIT symptom in palliative care — usually caused by opioids and immobility. Always prescribe a laxative when starting opioids!
  • Know the patient's normal bowel pattern — don't assume constipation based on days alone.
  • Pawpaw seeds are a culturally appropriate and highly effective laxative in the Ugandan context.
  • Privacy and dignity matter enormously for bowel care — never underestimate the psychological suppression of bowels.
  • Review, review, review — symptoms change, and so must your management.
💎 Final Clinical Pearl
In palliative care, GIT symptoms are rarely "just" GIT symptoms. Nausea may be from brain metastases. Diarrhoea may be from infection. Constipation may be the first sign of a fatal bowel obstruction. Always think broadly, assess holistically, and treat the root cause.

MOUTH SORES AND DIFFICULTY SWALLOWING (DYSPHAGIA)
Why Mouth Care Matters in Palliative Care

The mouth is often called the "mirror of the body." In palliative care, poor mouth care leads to:

  • Pain and difficulty eating
  • Infection (especially candidiasis in HIV-positive patients)
  • Loss of appetite and weight loss
  • Social isolation (bad breath, painful speech)
  • Reduced quality of life
💡 Key Message
Many mouth problems are preventable with simple, regular mouth care. This is a primary nursing priority. If the mouth is painful, the patient will not eat, drink, or take oral medications.
Causes of Mouth Sores and Dysphagia
Cause Explanation & Pathophysiology
Infections Oral candidiasis (very common in HIV), herpes simplex. (Fungal overgrowth occurs when systemic immunity drops or broad-spectrum antibiotics kill normal oral flora).
Mucositis Inflammation of the mouth lining from radiotherapy or chemotherapy. (Chemo attacks rapidly dividing cells; the basal epithelial cells of the mouth turn over every 7-14 days, making them highly vulnerable to sloughing off).
Ulceration From trauma, infection, or direct tumour invasion.
Poor dental hygiene Plaque, decay, gum disease.
Dry mouth (xerostomia) From medications (opioids, anticholinergics inhibit acetylcholine at muscarinic receptors on salivary glands), radiotherapy damaging salivary acinar cells, or mouth breathing.
Tumour erosion Tumours eroding through the buccal mucosa, sometimes causing fistulas (abnormal connections).
Nutritional deficiencies Iron deficiency (causes angular stomatitis), vitamin C deficiency (scurvy leading to bleeding gums).
Gastro-oesophageal reflux Acid irritation of the oesophagus causing strictures and swallowing pain.

🇺🇬 Uganda Clinical : In HIV-positive palliative patients, oral candidiasis is extremely common. Always inspect the mouth — white plaques on the tongue and buccal mucosa that bleed when scraped are classic. However, oesophageal candidiasis may occur even without visible oral thrush, causing severe odynophagia (painful swallowing). Treat empirically if symptoms align.

Assessment of the Mouth
What to Check What to Look For
Lips Dryness, cracking, colour (pallor, cyanosis), herpetic lesions.
Tongue Coating, colour, ulcers, mobility (assessing Cranial Nerve XII).
Buccal mucosa (inner cheeks) White plaques (candidiasis), redness, ulcers, bleeding.
Palate and throat Ulcers, swelling, white patches. Check gag reflex (Cranial Nerves IX and X).
Gums Bleeding, swelling, infection (gingivitis).
Teeth Decay, looseness, pain.
Saliva Amount (dry vs. excessive), consistency (thick/ropy indicates dehydration).
Nursing Tip: Use a torch and a tongue depressor (or clean spoon handle) for a thorough mouth examination. Document exactly what you see.
Non-Pharmacological Management
Intervention How to Do It
Regular mouth cleaning At least twice daily, and after meals.
Soft brush or cotton cloth Gentle brushing — avoid harsh scrubbing that damages fragile mucosa and causes bleeding.
Sodium bicarbonate or saline mouthwash A pinch in a glass of warm water. Rinse and spit. (Alkalizes the mouth, making it hostile to fungal growth).
Keep mouth moist Suck on ice chips, pieces of fruit (pineapple chunks contain bromelain which cleans the mouth), or sugar-free sweets to stimulate saliva.
Petroleum jelly on lips Prevents cracking and dryness.
Avoid alcohol-based mouthwashes Alcohol acts as a severe astringent and dries the mouth further, worsening xerostomia.
Patient and family education Teach them how to do mouth care at home to maintain autonomy.

🧠 Mnemonic for Mouth Care: "S-O-F-T C-A-R-E"

  • Soft brush or cloth
  • Oral inspection daily
  • Frequent rinsing with saline/bicarbonate
  • Treat infections promptly
  • Clean after meals
  • Avoid alcohol-based products
  • Remove dentures at night
  • Educate family
Pharmacological Management
Pain Management
  • Follow WHO Analgesic Ladder: Start with paracetamol, step up as needed.
  • Oral morphine: For severe mucositis pain — liquid formulation is heavily preferred if swallowing pills is difficult or impossible.
Oral Candidiasis
Drug Dose Notes / Mechanism
Nystatin oral drops 1–2 ml every 6 hours after food and at night Hold in the mouth for as long as possible before swallowing — this gives topical action (binds to ergosterol in the fungal cell membrane).
Fluconazole 50 mg daily for 5 days

OR

200 mg daily for 2 weeks
50mg: For localized oral candidiasis.

200mg: If oesophageal candidiasis is suspected (painful swallowing, no oral thrush visible). Systemic action.
Ketoconazole 200 mg daily Alternative to fluconazole; caution with severe hepatic drug interactions.
Nursing Exam Tip: Nystatin MUST be held in the mouth (swish and swallow) — not swallowed immediately — to work topically. If the patient swallows it straight away like water, it won't treat oral thrush effectively.
Other Infections
  • General sores / ulcers: Gentian Violet applied three times daily.
  • Foul-smelling mouth sores (especially oral cancer): Metronidazole mouthwash (anaerobic bacteria cause the foul rotting smell) — crush tablets or use IV injection liquid mixed with fruit juice to mask the metallic taste.
  • Herpes infections: Acyclovir 200 mg PO for 5 days; severe/disseminated cases need IV treatment.
Inflammation and Ulceration
  • Dexamethasone: 4–8 mg orally. Reduces inflammation; ONLY if infection is controlled — steroids worsen infection.
  • Prednisolone: Powder or solution. Alternative to dexamethasone.

⚠️ CRITICAL WARNING: STEROIDS IN MOUTH CARE
Never give steroids (Dexamethasone/Prednisolone) for mouth ulcers until infection is definitively ruled out or concurrently treated. Steroids suppress the local immune system (inhibit macrophages and lymphocytes) and will cause existing fungal or bacterial infections to explode out of control.

HICCUPS
What Are Hiccups? (Pathophysiology)

Hiccups are involuntary, spasmodic contractions of the diaphragm followed immediately by a sudden closure of the vocal cords (glottis), producing the characteristic "hic" sound. In palliative care, persistent hiccups are exhausting and distressing — they disrupt sleep, eating, and rest.

Anatomy of the Reflex Arc: Afferent impulses travel via the Vagus or Phrenic nerve to the Hiccup Center in the medulla. Efferent impulses shoot down the Phrenic nerve (spasming the diaphragm) and Recurrent Laryngeal nerve (snapping the vocal cords shut).

Causes of Hiccups
Mechanism Causes
Irritation of the phrenic nerve Tumours in the neck or mediastinum pressing on the nerve, enlarged lymph nodes.
Irritation of the diaphragm from below Stomach distension (gas/fluid), gastric tumour, hepatomegaly (enlarged liver pushing up), subphrenic abscess.
Central causes (brain) Brain metastases, stroke, uraemia irritating the medullary hiccup center.
Metabolic Uraemia (renal failure), severe electrolyte imbalance (hyponatremia, hypocalcemia).
Drugs Corticosteroids, some chemotherapy agents, benzodiazepines.
Nursing Tip: Always check for stomach distension first — this is a common, highly reversible cause. Inserting a nasogastric (NG) tube to decompress the stomach may instantly cure it.
Management of Hiccups
Immediate Non-Pharmacological Measures
Technique How It Works (Physiological Override)
Swallow dry bread or crushed ice Mechanically stimulates the Vagus nerve in the pharynx, interrupting the hiccup reflex arc.
Two spoonfuls of sugar Same mechanism — massive sensory pharyngeal stimulation resets the vagal tone.
Re-breathing from a paper bag Elevates blood CO2 levels (hypercapnia), which acts centrally on the medulla to suppress the hiccup reflex.
Sitting upright Reduces upward diaphragmatic pressure from heavy abdominal organs.
Correcting uraemia If renal failure is the cause, treat the underlying metabolic toxicity.
Pharmacological Management
Drug Dose Notes
Metoclopramide 10–20 mg every 8 hours Reduces gastric stasis and distension (empties the stomach, removing diaphragmatic pressure).
Haloperidol 3 mg at night Acts centrally on the brain to suppress the hiccup reflex arc.
Chlorpromazine 25–50 mg at night Also acts centrally; highly sedating (helps the exhausted patient sleep).
Clinical Pearl: If hiccups are due to gastric distension, metoclopramide is often the most effective because it treats the root cause. If due to central causes (brain metastases, uraemia), haloperidol or chlorpromazine work better.
GASTRO-OESOPHAGEAL REFLUX (GOR / GERD)
What Is Gastro-Oesophageal Reflux?

Gastro-oesophageal reflux occurs when stomach acid flows back into the oesophagus, causing a burning sensation ("heartburn"), regurgitation, and sometimes micro-aspiration into the lungs. Physiologically, it occurs when the Lower Oesophageal Sphincter (LES) fails to close tightly.

  • Abdominal tumour or ascites: Increased intra-abdominal pressure physically pushes stomach acid upward through the sphincter.
  • Neurological disorders: Reduced LES muscle tone.
  • Medications: NSAIDs directly irritate and destroy the protective mucosal lining of the stomach.
  • Prolonged lying flat: Gravity no longer keeps acid in the stomach (common in bedbound dying patients).
Management of Gastro-Oesophageal Reflux
  • Upright positioning: Keep patient sitting up (at least 30-45 degrees), especially for 1 hour after meals.
  • Give medications after meals: Food acts as a physical buffer for stomach acid.
  • Milk: Can temporarily soothe the oesophagus (though the calcium/fat may trigger a rebound increase in acid later in some patients).
  • Stop NSAIDs: If the patient is on NSAIDs (like ibuprofen/diclofenac), discontinue if possible — they aggressively worsen reflux and cause gastric bleeding.
  • Simple antacids: Magnesium trisilicate 10 ml every 8 hours (neutralizes existing acid).
  • H2 blockers: Cimetidine 200 mg every 12 hours; Ranitidine 300 mg every 12 hours (blocks histamine receptors on parietal cells, reducing acid production).
  • Proton pump inhibitors (PPIs): Omeprazole 20–40 mg once daily — completely shuts down the acid pump. Most effective for severe reflux.
Nursing Tip: In resource-limited settings, gravity positioning and stopping NSAIDs are completely free and highly effective interventions. Don't underestimate them!
DEHYDRATION
Understanding Dehydration in Palliative Care (Pathophysiology)

Dehydration is a complex and emotionally charged issue. Families often panic when a patient stops drinking, believing hydration is essential for life. However, in the terminal phase (last days/hours of life):

  • Reduced fluid intake is natural and appropriate. The body's organs are shutting down and can no longer process large fluid volumes.
  • Mild dehydration is physiologically beneficial: It raises blood osmolarity, which stimulates the release of endorphins (natural painkillers). It also decreases lung secretions (preventing the terrifying "death rattle") and decreases urine output (less need for painful catheterization/bedpan changes).
  • Forced IV hydration can cause fluid overload, leading to acute pulmonary edema (drowning in their own fluids), third-spacing (severe edema), and increased vomiting.
💡 Key Message
Dehydration in the dying patient is not always a problem to fix. It is often part of the natural, peaceful dying process.
When Is Dehydration a Problem vs. When Is It Natural?
Situation Is Dehydration a Problem? Action
Intercurrent illness (e.g., severe diarrhoea in a patient with months left to live) Yes — this is acute, distressing, and reversible. Rehydrate (Oral or IV).
Terminal phase (hours to days of life left) No — natural part of organ shut-down. Explain to family; focus entirely on aggressive mouth care.
Patient is thirsty despite terminal phase Maybe — assess carefully. Offer small sips, ice chips, keep mouth moist.
Dry mouth but not thirsty No — this is local mucosal dryness, not systemic intravascular dehydration. Mouth care, saliva substitutes, petroleum jelly on lips.
Risks of True Systemic Dehydration
  • Impaired drug excretion: Dehydration drastically reduces kidney perfusion/GFR. This causes morphine metabolites (like M6G) and other drugs to accumulate to toxic levels, causing opioid toxicity (sedation, myoclonic jerks, vivid hallucinations).
  • Distressing symptoms: Hallucinations, muscle twitching, terminal restlessness/agitation.
  • Dry mouth: Often vastly more distressing to the patient than the actual feeling of systemic thirst.
Assessment of Dehydration
  • Dry mouth and lips: Usually local dryness (mouth breathing/drugs), not necessarily systemic dehydration.
  • Thirst: May indicate true dehydration, but also common in simple dry mouth.
  • Reduced urine output: Normal in terminal phase; dark, concentrated, highly odorous urine indicates dehydration.
  • Sunken eyes, poor skin turgor: Signs of significant intracellular fluid loss.
  • Tachycardia, hypotension: Late signs of severe intravascular fluid loss (hypovolemia).
Nursing Tip: A patient can have a dry mouth but not be dehydrated. Frequent mouth care (moistening, lubricating) often entirely relieves the symptom without needing a single drop of IV fluids.
Management & Family Communication
Approach When to Use How
Mouth care only Terminal phase, no distress. Keep mouth and lips clean and moist; this is often all that is needed.
Small oral sips Patient is thirsty and can swallow safely (intact gag reflex). Ice chips, tiny sips of water via syringe or spoon.
Subcutaneous (SC) fluids (Hypodermoclysis) Patient needs hydration but cannot swallow; less invasive than IV. Can be given easily at home with a butterfly needle in the thigh/abdomen.
IV fluids Severe dehydration with a reversible cause; hospital setting. Requires venous access; high risk of fluid overload (pulmonary edema) if heart/kidneys are failing.

⚠️ CRITICAL WARNING
Offering large volumes of oral fluids to a dying, semi-conscious patient risks catastrophic aspiration pneumonia. In the terminal phase, forcing more than tiny sips is physically dangerous.

Discussing Dehydration with Families:
  • "Won't they suffer without water?" -> "In the final days, the body naturally shuts down and needs less fluid. Forced fluids pool in the lungs and cause choking. We will keep their mouth highly comfortable."
  • "They look so dry!" -> "We will use moist cloths, lip balm, and mouth swabs to keep the mouth comfortable. A dry mouth is different from whole-body thirst."
  • "Should we give them water?" -> "Only small sips or ice chips if they are awake, thirsty, and can swallow safely. Otherwise, we focus on mouth care."
CACHEXIA AND ANOREXIA
What Is Cachexia? (Pathophysiology)

Cachexia is a profound wasting syndrome characterised by severe weakness, massive weight loss (breakdown of both skeletal muscle and adipose fat), and poor appetite (anorexia). It is seen in advanced cancer, HIV/AIDS, and end-stage organ failure.

Critical Understanding: Cachexia is NOT caused by starvation or lack of food. It is a metabolic disorder driven by inflammatory cytokines (like TNF-alpha, Interleukin-6, and Proteolysis-Inducing Factor secreted by tumours). These chemicals reprogram the body into a hyper-catabolic state, destroying muscle tissue even if the patient is eating 3000 calories a day. Therefore, forced feeding will NOT reverse it.

Why Forced Feeding Doesn't Work
Myth Reality
"If they just ate more, they'd get better." Cachexia is metabolic, not nutritional. The tumour/virus alters metabolism so the body cannibalizes its own muscle and fat despite adequate intake.
"They must be starving." Patients with cachexia physiologically do not feel hungry (anorexia). Normal starvation is painful; cachexia is painless fading.
"IV/Tube nutrition will help." Parenteral (IV) or Enteral (Tube) nutrition in advanced cancer does not improve survival or quality of life. It only feeds the tumour and causes fluid overload, edema, and infection.
Reversible Causes of Anorexia (Rule these out first!)
  • Lack of available/digestible food: Provide preferred foods, small frequent meals.
  • Dysphagia: Assess swallowing; modify food texture (puree).
  • Sore mouth or altered taste: Treat oral candidiasis, ulcers; offer flavourful foods (tumours often make meat taste bitter/metallic).
  • Dyspepsia, nausea, vomiting: Treat with antiemetics, antacids.
  • Constipation: A completely full colon sends signals to the brain to stop eating. Treat with laxatives!
  • Pain: Severe pain kills the appetite. Treat with analgesia.
Management of Cachexia
  • Treat all reversible causes listed above.
  • Small, frequent, appealing meals: Don't force large portions on large plates (this overwhelms and nauseates the patient). Serve food on small saucers.
  • High-calorie, high-protein foods: Make every single bite count (add butter, cream, sugar to foods).
  • Corticosteroids: (e.g., Dexamethasone). May artificially stimulate appetite and improve well-being for a short term (2-4 weeks). Not useful long-term due to severe side effects (muscle weakness, immunosuppression).
  • Psychological support: Eating is deeply social. Encourage family presence, create a pleasant environment. Avoid turning meals into a battlefield of forced feeding.

⚠️ WARNING: Corticosteroids in Children
Do NOT use corticosteroids (like Dexamethasone or Prednisone 0.05–2 mg/kg) in children solely to treat anorexia/cachexia. Only use if the anorexia is associated with severe nausea, unremitting pain, asthenia (weakness), or depressed mood.

FAECAL INCONTINENCE
Why It Is So Distressing

Faecal incontinence completely strips patients of their dignity, causes severe psychological withdrawal, and places an enormous, exhausting physical burden on family caregivers. It requires hyper-sensitive, practical nursing care.

Causes & Assessment
Cause Explanation / Assessment Action
Faecal impaction (Overflow) Hard rock of stool blocks the rectum; liquid stool leaks around it. Action: Perform a Digital Rectal Exam (DRE) to feel for impaction.
Excessive laxative use Over-treatment of constipation causes loose stools. Action: Review medication chart.
Severe diarrhoea in debilitated patients Patient is simply too weak to voluntarily squeeze the external anal sphincter.
Paraplegia (Spinal Cord Injury) Loss of spinal cord motor control over the external anal sphincter. Action: Assess neurological level.
Relaxed anal sphincters (elderly) Age-related or disease-related muscle wasting of the sphincter complex.
Ano-rectal tumours Direct tumour destruction of the sphincter mechanism. Action: Inspect perianal area for masses/fistulas.
Management by Cause & Practical Home Care
  • Relaxed sphincters: Use constipating agents deliberately (Loperamide or Codeine phosphate) to firm up the stool.
  • Paraplegia: Institute a regular bowel regimen (e.g., daily glycerine suppositories to stimulate controlled rectal evacuation).
  • Ano-rectal carcinoma: Palliative radiotherapy to shrink tumour; rectal steroids (prednisolone suppositories) for inflammation; crushed metronidazole rectally to kill anaerobic bacteria causing offensive rotting discharge.
  • Faecal Impaction: Manual disimpaction, enemas, then establish a daily laxative regimen.
  • Home Care: Use plastic under-sheets (mackintosh) and adult diapers. Clean and dry the skin promptly after every episode to prevent acidic stool from burning the skin. Apply heavy Zinc Oxide barrier cream. Keep the room smelling fresh and use privacy screens to fiercely protect the patient's dignity.

❓ Exam-Style Application Questions

Question: A patient with advanced HIV has painful swallowing but no visible white patches in the mouth. What is the likely diagnosis, and what would you prescribe?
Answer: Oesophageal candidiasis — thrush can aggressively affect the oesophagus without any oral involvement. Prescribe systemic Fluconazole 200 mg daily for 2 weeks.

Question: A dying patient has not drunk fluids for 48 hours. The family insists on starting IV fluids. How do you respond?
Answer: Explain that reduced fluid intake is natural in the terminal phase. Forced hydration risks aspiration pneumonia, pulmonary edema, and does not prolong life or improve comfort. Focus heavily on mouth care to keep the mouth moist. If the patient is awake and thirsty, offer small sips or ice chips.

Question: A patient with oral ulcers is prescribed dexamethasone 4 mg. What must you check first?
Answer: Rule out or treat infection first! Steroids will drastically worsen fungal or bacterial infections. Inspect for candidiasis, herpes, or bacterial infection. Treat the infection, THEN consider steroids for inflammation.

Question: What is the physiological difference between starvation and cachexia?
Answer: Starvation is a simple lack of caloric intake and is easily reversed by feeding. Cachexia is a hyper-catabolic, inflammatory wasting syndrome driven by cytokines (TNF-alpha, IL-6) that force the body to destroy its own muscle and fat. It is NOT reversed by forced feeding.

SUMMARY: KEY NURSING POINTS
  • Mouth care is prevention: Regular cleaning prevents most devastating oral problems.
  • Oral candidiasis is extremely common in HIV: Inspect the mouth daily using a torch.
  • Nystatin must be held in the mouth: It requires topical contact action. Don't let patients swallow it immediately like a pill.
  • Never give steroids for mouth ulcers: Until infection is explicitly ruled out or treated.
  • Hiccups: Often caused by gastric distension — Metoclopramide effectively treats the root cause by emptying the stomach.
  • Reflux management: Starts with positioning upright and stopping NSAIDs — these interventions cost absolutely nothing.
  • Dehydration in terminal phase is natural: Meticulous mouth care, not forced IV fluids, is the absolute priority.
  • Cachexia is metabolic, not nutritional: Forced feeding does not help, does not build muscle, and only causes severe emotional and physical distress.
  • Faecal incontinence is often overflow: Always assess with a rectal exam for impaction before blindly treating it as diarrhoea.
  • Dignity is central: Protect the patient's self-respect at every step when managing all GIT symptoms.
