Question

When the duration of tourniquet inflation is longer than 2 hours, inform the surgeon about deflating the tourniquet for ___ to allow tissue repercussion

a) 5-10 minutes
b) 10-15 minutes
c) 15-20 minutes
d) 2-3 minutes

Answer 1

For a tourniquet inflated longer than 2 hours, it is recommended to deflate it for 15-20 minutes to allow for tissue reperfusion.

Step-by-step explanation:

When the duration of tourniquet inflation exceeds 2 hours, it is recommended to inform the surgeon to deflate the tourniquet for a period of 15-20 minutes to allow for tissue reperfusion. This practice helps to prevent potential tissue damage due to prolonged ischemia. The vascular spasm response, which involves the constriction of blood vessels and can be triggered by vessel injury, typically lasts up to 30 minutes. During tourniquet deflation, it is crucial to monitor the area for adequate blood flow and to ensure that any potential bleeding is controlled.
