For how long should the needle be kept inserted during a Z-track injection?

In a Z-track injection, the needle should typically be kept inserted for about 10 seconds after the injection of the medication. This technique is important because it minimizes the discomfort caused by the injection and prevents the medication from leaking back into the subcutaneous tissue, which can lead to irritation or staining of the skin.

The Z-track method involves displacing the skin and subcutaneous tissue laterally to create a zig-zag pathway that traps the medication in the muscle tissue. Keeping the needle inserted for a short duration allows for adequate time for the medication to be deposited correctly and for the muscle to start absorbing it, thus reducing the risk of leakage.

This method is particularly used for injections that are irritating or may stain the tissue, such as certain intramuscular medications. By adhering to the 10-second guideline, healthcare professionals can ensure optimal administration of the medication while maintaining patient comfort and safety.
