The suspension should be administered by deep intramuscular injection within the fleshy muscles of the hip, rump, round or thigh, or into the neck, changing the site for each injection. Do not inject subcutaneously, into a blood vessel, or near a major nerve. Use a 16 or 18 gauge needle, 1.5 inches long.
Giving the Injection
Hold the syringe in the hand you write with like a pencil or dart. With your other hand, pinch the skin between the thumb and index finger. Insert the needle quickly into the pinched skin at a 45° (slight angle for subcutaneous) or 90° (straight for intramuscular).
Intramuscular injections are often given in the following areas:
Make sure you pinch up on subcutaneous tissue to prevent injection into the muscle. Insert needle at a 45° angle into the fatty tissue overlying the triceps muscle. Make sure you pinch up on the subcutaneous tissue to prevent injection into the muscle.
A subcutaneous (SC) or intramuscular (IM) injection is almost always painless if the skin is stretched firmly before inserting the needle. If injecting the arm, for example, the third, fourth and fifth fingers should go medial to the arm while the thumb and index finger stretch the skin on the lateral surface (Fig.
Penicillin V given orally was thus shown to be an acceptable alternative to parenteral administration of penicillin in the horse.
The daily dose of penicillin is 3,000 units per pound of body weight (1 mL per 100 lbs body weight). Continue daily treatment until recovery is apparent and for at least one day after symptoms disappear, usually in two to three days. Treatment should not exceed four consecutive days.
The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.
Erroneous injection location may cause severe damages
If the muscle to be injected is small then so should the dose. [ In a small muscle the injection may cause more pain and damage . If you repeatedly inject in the same location, the muscle can harden and become damaged.
Intramuscular (IM) injections
Needle length is usually 1″–1½”, 22–25 gauge, but a longer or shorter needle may be needed depending on the patient’s weight.
21 (green) and 23 (blue) gauge needles are most commonly used. The needle should be held at a 90° angle to the skin (see diagram) and gently aspirated preinjection to ensure that the needle has not entered a blood vessel.
