Summary

This randomized, triple-blind clinical trial compares the effectiveness of Z-track and TPR (traction-pressure-release) techniques in reducing pain and medication leakage during ventrogluteal intramuscular injections. Pain is measured using VAS, and leakage is assessed with a millimeter scale. The study aims to identify a more efficient, less painful injection method.

Conditions

  • Muscle Pain
  • Injection Site Pain

Interventions

OTHER

Z-track method

Z-track method, the skin will be pulled laterally by 2.5-3.5 cm before needle insertion at a 90-degree angle. After aspiration and injection, the needle will be withdrawn and the skin released immediately.

OTHER

TPR method

TPR method, while the needle is inserted at a 90-degree angle, deep pressure will be applied to the muscle, then rapidly released to create a snapping motion that facilitates the injection. This technique relies on rapid muscle relaxation rather than needle movement by the dominant hand.
