Study Notes
Types of Injections
- There are four types of injections: Intramuscular, Subcutaneous, Intradermal, and Intravenous.
Intramuscular Injections
- Indications for IM injections: when rapid response is required, dysphagia, profound vomiting, and no availability for oral preparation.
- Common sites for IM injections: Mid Deltoid, Dorsalgluteal, Rectus femoris, and Vastus lateralis.
- Amount of injection for IM: up to 5 mL in the buttocks, and up to 1 mL in the deltoid.
- Equipment needed: sterile syringe, drug, alcohol swab, non-sterile gloves, and Band-Aid.
- Technique involves identifying the patient, explaining the procedure, and taking permission, among other steps.
- Complications of IM injections: pain, injury to the sciatic nerve, tissue necrosis and abscess, hemorrhage, and infection.
Subcutaneous Injections
- Volume usually less than 0.5 mL.
- Administered through a ½ inch, 23- or 25-gauge needle.
- Indications are the same as IM injections.
- Best and most commonly used for regular injections of Insulin for Insulin-dependent diabetic patients.
- Sites for Subcutaneous Injections: abdomen, arms, and thighs.
- Technique involves elevating subcutaneous tissue, removing the needle cap, and inserting the needle at a 45- or 90-degree angle.
- Complications of Subcutaneous Injections: pain, infection, and allergic reaction.
Intradermal Injections
- Small amounts are injected into the layers of skin.
- Often used to test for allergic reaction and antibody formation.
- Usual site: anterior forearm.
- Angle of insertion: almost parallel to skin (10o-15o).
- Technique involves rubbing the injection site vigorously with a swab, inserting the needle parallel with the forearm, and releasing the solution into the skin layers.
Comparison of Angles
- Intramuscular injection: 72o-90o angle.
- Subcutaneous injection: 45o or up to 90o angle if fat layer is thick and the needle is short.
- Intradermal injection: 10o-15o angle.
