Top Mistakes to Avoid When Using a Tourniquet in the Field?

Improper Placement

Improper placement of the tourniquet is a common mistake that can lead to inadequate blood flow restriction. The tourniquet should be placed 2-3 fingerbreadths above the wound site, with the windlass tightened to 1.5-2 times the patient’s arm circumference. This ensures that the tourniquet is above the brachial or femoral artery, but not too close to the wound site, which can cause further damage.

Excessive Force

Applying excessive force when tightening the tourniquet can cause further injury to the patient, including nerve damage, muscle necrosis, and even amputation. To avoid this, apply gentle but firm pressure, and use a windlass to tighten the tourniquet in a controlled manner. The tourniquet should be tightened in increments of 1-2 turns every 10-15 seconds, until the desired level of blood flow restriction is achieved.

Inadequate Assessment and Monitoring

Inadequate assessment and monitoring of the patient’s condition can lead to complications, including compartment syndrome, nerve damage, and even death. Before applying a tourniquet, assess the patient’s condition, including their pulse, blood pressure, and level of consciousness. Monitor the patient’s condition regularly, checking for signs of complications, including pain, numbness, or tingling in the affected limb.
