What is the treatment of choice for the first leading cause of preventable death on the Battlefield?

• A. The hasty application of a tourniquet is the recommended management for all life-threatening extremity hemorrhages during combat casualty care.
• B. Apply a pressure bandage and monitor
• C. Elevate limb and apply pressure
• D. Administer IV fluids immediately

Answer: (A)

Stopping life-threatening extremity bleeding as quickly as possible is the highest priority in battlefield trauma care. The quickest and most reliable way to do that is to apply a tourniquet promptly, creating a high and tight constriction above the wound to halt arterial and high-flow bleeding. This hasty tourniquet approach directly reduces the chance of death from hemorrhage and has become the standard first-line intervention in combat casualty care.

Pressure bandages and monitoring can help with lighter or venous bleeds, and elevating the limb with pressure may assist in some situations, but they’re not consistently effective for severe, life-threatening bleeding. Administering IV fluids right away doesn’t stop the bleeding and may delay control of the hemorrhage, which is why stopping the bleed comes first.
