ROUTES OF DRUG ADMINISTRATION
Injections, which include
- Skin topical
- Ocular drops
- Mucosal-throat, vaginal, ear,…
Refer to Pharmacology for details about other routes of administration that havent been explained here.
Inhalation is the breathing of air vapour or volatile medicine into the lungs.
- Moist/steam inhalation
- Dry inhalation
It is used in case of inflammation of air passages and the nasal sinuses.
Vapor is inhaled like in asthma.
-Respiratory diseases eg asthma, pneumonia
-Chest injuries and -Cardiac failure
DRY INHALATION (Oxygen administration)
It is given when the respiratory tract is diminished as in chest injuries, cardiac failure and
REQUIREMENTS FOR OXYGEN ADMNISTRATION
-BLB oxygen mask
-Galipot with gauze pads
-Humidifier with distilled water
- Follow the general rules of drug administration.
- Determine the need of oxygen therapy in patients and check physicians order for rate, device used,
concentration to reduce the risk of errors in administration.
- Position the patient in sitting up position to promote comfort.
- For nasal cannula, connect nasal cannula to oxygen, set up with humidification, check if oxygen
is flowing to prongs.
- Place prongs in the patients nostrils two inches,place tubing over and behind each ear with
adjuster comfortably under the chin or place tubing around the patients head with the adjuster
at the back or base of the head and place gauze pads at the ear beneath the tubing as necessary
to reduce irritation and pressure.
- Encourage the patient to breath through the nose, with the mouth closed to provide optimal
delivery of oxygen the patient.
- For BLB mask use or attach face mask to oxygen source, start the flow of oxygen at a specified
rate, for a mask with a reservoir, a low oxygen to fill the bag, before proceeding to the next step
to promote oxygen supply.
- Position the face mask over the patients mouth adjust the elastic strap around patients head,
adjust the flow rate.
- Apply the pad behind the ear as well as scalp elastic band passes to prevent irritation.
- Re-assess patients respiratory status ,including respiratory rate ,effort and lung sound .To
check effectiveness of oxygen therapy.
- Document relevant information in patients chart.
ADMINISTRATION OF MEDICINE THROUGH INTRAVENOUS INFUSION
A TROLLERY [STRILE PROCEDURE]
Bowl containing 2 sterile towels
Galipot of swabs
Galipot of antiseptic solution
1 dissecting forceps
1 bottle of antiseptic solution
Cheatle forceps in a jar
Tourniquet or sphygmomanometer
Draw mackintosh and dressing towel
A drum of sterile swabs
Cannula in appropriate size, 2ml syringe and needle
AT THE BED SIDE
Drip stand on which to hang the bottle
Extra pillow covered with a mackintosh
Screen hand washing equipment
Sharps safety box
- Refer to general and injection medication rules .
- Prepare the injection trolley and take to the patients bed side
- Put on gloves to prevent cross infection.
- Place a small pillow and protective sheet under the patient`s arm, to avoid soiling of linen.
- Prepare the medication to be administered , fix it on the intravenous line , fill the fluid chamber to half way ,expel the air and fix it on a drip
- Expose the patient`s fore arm depending on the site
- Request the patient to close and open his or her fist for a minute
- Select a vein, apply a tourniquet around the patient’s upper arm, to dilate the vein.
- Request the patient to close and open his or her fist for a minute
- Clean the area with antiseptic from center outward In circular motions covering several centimeters and permit solution to dry on the skin.
- Pull the skin taut bellow the entry site using the non-dominant hand, To stabilize the vein and make skin
taut for needle entry.
- Hold cannula needle at 20 to 30 degree angle with sharp beveled end up insert it in the skin and into the vein, to reduce the degree of counter puncture.
- Once blood is seen in cannula remove tourniquet then the trocher slowly while adjusting the cannula inside the vein, to avoid puncturing the vein with the trocher.
- Apply pressure to the vein immediately above the end of cannula, To prevent blood flow.
- Attach medication line to the cannula and regulate the rate of flow using the clip, To give right amount of medicine at
the right time
- Clean up any blood and secure the cannula with plaster, To ensure the cannula is held securely in place.
- Record the date and time of starting the infusion.
Leave the patient comfortable
and clear away.
Wash hands and document the procedure.
SOME OF THE RECOMMENDED VEINS FOR INTRAVENOUS INFUSION
BACK OF THE HAND
Dorsal metacarpal veins
INNER ASPECT OF THE ELBOW
[ANTE CUBITAL FOSSA]
Medial basilic vein
Median cephalic vein
Femoral and saphenous vein in the thigh
Dorsal venous plexus, medial and lateral marginal veins in the foot
These may be useful in infants and elderly
THE COMPLICATIONS OF INTRAVENEOUS INJECTIONS
- Necrosis occurs if the medicine goes into the surrounding tissues.
- Damage to the arteries if the medicine is injected accidentally into the arteries.
- If medicine is administered rapidly without following doctor`s instructions un
desired effects may occur.
- Circulatory overload.
FORMULAR FOR CALCULATING THE DROP RATE
Number of mls drops per min
Ordered × drop factor = drops to infuse per minute
Number of hours 60 minutes
The doctor has prescribed 1000 mls of 5% dextrose infusion to run in 10 hours’ time.
- How many drops per minute will you regulate if infusion set has a drop factor of 20?
1000×20 = 33.3 drops per minute
10 x 60
FACTORS THAT MAY AFFECT THE FLOW RATE
- Height of the infusion bottle: raising the infusion bottle higher will increase the
rate of flow and lowering it will decrease the rate.
- Patency of infusion set and needle: a blood clot in the needle may stop the
infusion, the may result when there is a delay in changing the emptied infusion
- Kinking of the tubing or faulty position of the needle e.g. when the needle is
against or away from the vein wall.
- A tight splint on or above the infusion needle will restrict the flow rate.
- A blocked air or vent will cause the infusion to stop from running.
CARE OF THE PATIENT WHILE ON INTRAVENOUS INFUSION
- Keep an accurate record, including the time of starting the infusion, type of the
fluid and the amount and the prescribed rate of flow.
- Assess the patient at frequent intervals for signs of abnormal reaction such as
pain, sweating, restlessness or change of colour.
- Inspect the site at regular intervals for signs of infiltration.
- Take and record the patient`s condition.
- If the infusion is running for some days, cleanse the area around the injection site
with sterile gauze daily.
Blood transfusion refers to the intravenous replacement of lost or destroyed blood with compatible human blood.
TYPES OF BLOOD PRODUCTS
- It is indicated to patients experiencing acute massive loss of blood or hypovolemic
It restores volume and raises hemoglobin count and therefore oxygen capacity.
PACKED RED BLOOD CELLS
- Red blood cells are separated from a unit of whole blood.
80% of plasma is removed leaving packed red blood cells which may be transfused to a
patient to increase the number of red blood cells without overloading the circulatory
system with fluids.
Certain types of anaemia such as a plastic anaemia may be treated by this blood
- Platelets may be administer to aid haemostasis in patients suffering from
Platelets in initiating clotting process and other clotting factors such as prothrombin,
fibrinogen and thromboplastin.
- Plasma is used to expand blood volume in cases of shock, burns, hemorrhage and while
waiting for blood to cross matched.
INDICATIONS OF BLOOD TRANSFUSION
- In cases of severe anaemia due to pregnancy, sickle cell disease, complicated
- Preoperatively in case of reduced blood volume level
- Severe burns
- Post operatively i.e. after major surgeries e.g. laparotomy, open reduction of internal fractures, total abdominal hysterectomy
- Trauma following RTA [road traffic accidents]
- When the patient lacks certain substances such as plasma or clotting factor
- When a patient has a certain type of anaemia which cannot be treated by other measures.
NOTE: as for intravenous infusion with addition of the following:
A TROLLEY [STERILE PROCEDURE]
-Blood giving set with a filter
-Large needle or cannula
-Unit of blood
-Observation chart, fluid balance chart
-Patient`s chart with details of transfusion
-Medicines as prescribed
NOTE: the technique of blood transfusion is similar to blood transfusion
On completion of the transfusion the empty bottle for 24 hours incase it’s needed for
testing in case of reaction.
Record the following on the patient`s chart:
-Number of the blood bottle.
-Amount of blood transfused.
-Names of nurses or doctor who checked the blood and set up the transfusion .
Urinary out put.
Administer normal saline before and after blood transfusion.
THE COMPLICATIONS OF BLOOD TRANSFUSION
The following are some of the adverse reactions which may occur during blood
- Some patients may be hypersensitive to some substances contained in blood which he/she is receiving
Signs and symptoms
- Itching, flushing, urticarial, signs of respiratory distress and anaphylactic shock
- Stop the transfusion immediately
- Urgently inform doctor
- Give anti histamine if prescribed
While the transfusion is in progress, the patient may develop fever accompanied by
chills and headache. If this happens:
- Stop the transfusion at once and notify the doctor
- Treat the patient symptomatically such as giving him or her an extra blanket or giving the prescribed antipyretics
- Re assure the patient
This is a serious reaction. It occurs when the donor`s blood is not compatible with that of a recipient
The signs and symptoms
- Lower back pain
- Nausea and sometimes vomiting
- Patient may have haemoglobinuria

- Stop the transfusion immediately and notify doctor
- Keep the vein open with normal saline
- If the patient is shocked treat for shock
- Keep blood for rechecking at the blood bank
- Take the blood samples from the site
- Collect a urinary specimen to determine haemoglobinuria
- Give a diuretic as prescribed by the doctor
NOTE: if the volume of blood administered is greater than what the circulatory system
can conveniently accommodate, the patient will have;
- Distended neck veins
- Dry cough and pulmonary oedema
-Stop the transfusion and notify the doctor who may order to stop completely or
to give at slower rate.
-Administer prescribed medicines.
-Check and record vital signs at different intervals.
The blood or equipment for giving the blood may be contaminated with bacteria. Patient
will manifest with the following signs and symptoms
- High fever
-Stop the transfusion immediately
-Tepid sponge the patient
-Inform the doctor and the blood bank
-Monitor the vital signs
-Give antibiotics and antipyretics as prescribed by the doctor
DISEASES THAT CAN BE TRANSMITTED THROUGH BLOOD TRANSFUSSION
