Which technique is important to prevent tissue irritation during injection?

The Z-track method is an important technique used to prevent tissue irritation during injection, especially when administering medications that can be irritating to the subcutaneous tissues, such as certain intramuscular injections. This method involves creating a zigzag path for the needle as it enters the body, which helps to seal the medication in the muscle tissue and minimizes the potential for leakage into the subcutaneous layer. Additionally, this technique helps in reducing discomfort as it forces the tissue to close over the injection site, providing a barrier that can also prevent irritation and staining of the skin.

The Z-track method specifically addresses the issue of preventing irritation by ensuring that the medication stays where it is intended to be delivered and keeps other tissues from being exposed to it.
