Results of combat medic junctional tourniquet training: a prospective, single-blind, randomized, cross-over study.

Background: Bleeding remains the leading cause of potentially preventable deaths both in military and civilian pre-hospital trauma settings. Conventional extremity tourniquets do not control bleeding if an iliac artery or a common femoral artery is injured. Stopping junctional bleeding is particularly challenging and requires the use of specifically designed junctional tourniquets.
