- 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.
