Which technique is used to reduce leakage and tissue trauma when performing intramuscular injections?

• A. Aspirating before injection
• B. Massaging the site after injection
• C. Keeping the skin taut during injection
• D. Z-track technique

Answer: (D)

Techniques to minimize leakage and tissue trauma during intramuscular injections are being tested here, and the best method is the Z-track technique. By pulling the skin and underlying tissues to one side before inserting the needle and releasing them after the injection, you create a new path for the needle that seals the track. This movement channels the medicine into the muscle and prevents it from seeping back along the needle tract into subcutaneous tissue, which reduces staining and tissue irritation. It also reduces trauma because the needle passes through tissue in a way that lowers friction and tearing. Aspirating before injection is about checking for a blood vessel to avoid intravascular administration, not about preventing leakage or tissue trauma. Massaging the site after injection can disperse medication and irritate tissue, potentially increasing discomfort rather than reducing leakage. Keeping the skin taut helps with needle insertion and depth control but does not seal the needle track to prevent leakage into subcutaneous tissue.
