What is the best way to control a traumatic hemorrhage?

Using a tourniquet if bleeding is severe is considered the best way to control traumatic hemorrhage in critical situations. A tourniquet is specifically designed to impede blood flow to a limb, significantly reducing the risk of exsanguination—the loss of a dangerous volume of blood. When applied correctly above the site of injury, a tourniquet can effectively stop profuse bleeding from severely damaged blood vessels, providing an immediate life-saving measure until further medical intervention can be achieved.

In circumstances where the hemorrhage is life-threatening and other methods such as direct pressure, elevation, or pressure bandages have failed or are not adequate, the use of a tourniquet is essential. It is important to note that the application of a tourniquet is typically reserved for severe trauma, where the risk of death from blood loss outweighs concerns about potential complications from limb ischemia or the need for surgical intervention later on.

The other options have their merits in controlling less severe bleeding situations but may not be sufficient in extreme cases. Although applying direct pressure can be effective for mild to moderate bleeding, it may not fully control the blood loss in severe cases. Elevating the extremity can help in some situations but is generally secondary to direct pressure and tourniquet application
