- 4. A method of administering medications directly into muscle tissues.
- 5. INDICATIONS CONTRAINDICATIONS Administration and absorption of large doses (up to 5 ml) in appropriate sites Medications that irritate subcutaneous tissues Cannot locate an appropriate vein Drugs that are altered by digestive juices Un cooperative /cannot take medications orally Active infection near the injection site A known allergy or hypersensitivity to the material or to the lidocaine Acute myocardial infarction Shock Coagulation disorders
- 7. Deltoid muscle Feel for the bone at the top of the upper arm (Acromion process) . Two finger-widths below this, there is a inverted triangular muscle. The needle should enter the centre of triangle. The maximum amount of medication for a single injection is 1 ml.
- 8. Vastus lateralis muscle of the thigh Commonly used for immunizations in children. This muscle is located on the anterior lateral aspect of the thigh and extends from one hand’s breadth above the knee to one hand’s breadth below the greater trochanter. The middle third of the muscle is used for injections. The maximum amount of medication for a single injection for adult is 3 ml and Children is 0.5ml to 1 ml
- 9. Ventrogluteal muscle of the hip Locate the greater trochanter of the femur with the palm of the hand. Spread index and middle fingers posteriorly from the anterior superior iliac spine to the furthest area possible Position the index and middle fingers into a ‘V’ then administer in the middle of the V. The maximum amount of medication for a single injection for adult is 2.5 to 5 ml
- 10. The ventrogluteal site is free from blood vessels and nerves, and has the greatest thickness of muscle when compared to other sites
- 11. Dorsogluteal muscle of buttocks Due to the potential injury to the sciatic nerve this site is not recommended.

- 13. In an adult, the most commonly used needles are 1 or 1 ½ inch long and 18 to 25 Gauge thick. An aqueous solution : 20 to 25 gauge needle. Viscous or oil-based solutions :18 to 21 gauge needles. Children: 1 – 1 ¼ inch long and 22 to 25 Gauge thick Safety needles should be used for IM injections to reduce the risk of needle-stick injury
- 14. The Z-track method is a type of IM injection technique used to prevent tracking (leakage) of the medication into the subcutaneous tissue. Z-Track Injection Sites Thigh (vastus lateralis muscle) Hip (ventrogluteal)
- 15. Purpose of Z-Track Injection It helps to prevent medication from seeping into the subcutaneous tissue and ensures a full dosage. Some medications are dark colored (iron preparation) and can cause staining on the skin. This technique is to prevent injection site discoloration or lesions.
- 16. Procedure Skin and tissue are pulled and held firmly while a long needle is inserted into the muscle. Pulling the skin and tissue before the injection causes the needle track to take the shape of the letter “Z,” This zigzag track line prevents medication from leaking from the muscle into surrounding tissue.
- 18. Create Z-track. Keep the needle in place for about 10 seconds before taking it out. After removing the needle, release the hold on the skin and tissue. Apply pressure to the site. Use gauze to apply gentle pressure to the site for a moment. Never massage the site .This may cause the medication to leak and irritate the skin.
