Quick Answer
A tourniquet that's not working may show signs such as increasing bleeding, no significant reduction in bleeding, or continued signs of shock. Look for pale or cool skin on the affected limb and decreased or absent pulses. If the tourniquet is not effective, the wound should be reassessed and the tourniquet reapplied or replaced.
Signs of Ineffectiveness
When assessing a tourniquet’s effectiveness, it’s essential to look for specific signs. The most notable indicator is the lack of bleeding control. If the bleeding doesn’t significantly decrease or even appears to increase, the tourniquet is likely not functioning correctly. The skin on the affected limb should also be checked for signs of circulatory failure, such as pallor, coolness, or decreased sensation.
Reevaluation and Reapplication
In the event of a tourniquet not working, it’s crucial to reassess the situation and take immediate action. This involves releasing the tourniquet and reapplying it at a new site, ideally higher up the limb. The new tourniquet should be applied 2-3 inches proximal to the previous site, ensuring optimal constriction. It’s also crucial to recheck the bleeding and limb for signs of circulatory failure. If bleeding continues or worsens, consider using a second tourniquet, but never apply more than two tourniquets on the same limb. If available, consider using hemostatic agents or applying pressure with a dressing to control bleeding while reapplying the tourniquet.
