To minimize nerve or tissue damage when using a tourniquet, which practice is essential?

• A. Apply appropriate pressure, set correct duration, monitor time, and release gradually to restore blood flow.
• B. Apply excessive pressure and maintain it until the incision is closed.
• C. Leave the tourniquet in place until wound closure.
• D. Cover the tourniquet with a sterile drape to maintain sterility.

Answer: (A)

Controlling perfusion safely is the goal: use just enough pressure to stop arterial flow, set a sensible time limit for the tourniquet, monitor that timing, and release gradually to restore blood flow. This approach protects nerves and surrounding tissues from the harm of prolonged ischemia and the stress of sudden reperfusion, reducing the risk of nerve injury, muscle damage, and delayed healing. Applying excessive pressure or leaving the tourniquet in place until wound closure creates extended ischemia and greatly increases these risks. While keeping the area sterile is important, simply covering the tourniquet does not prevent nerve or tissue damage if pressure or duration aren’t managed correctly.
