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.
17.
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.
