Smith S, et al. - Junctional tourniquets, that apply external compression to stop blood flow in the groin and axilla, have been incorporated into tactical combat casualty care for junctional vascular trauma. Researchers here assessed the effectiveness in achieving arterial occlusion as the primary outcome and determined the time to application and pain scores as the secondary outcomes. They analyzed 8 studies reporting the effectiveness of junctional tourniquets in healthy volunteers. Outcomes suggest the possible utility of junctional tourniquets for meeting a medical need in combat, and in the civilian environment, to control hemorrhage from these difficult injuries. In healthy volunteers, all four Food and Drug Administration–approved devices [the abdominal aortic and junctional tourniquet (AAJT), the junctional Emergency Treatment Tool, the SAM junctional tourniquet (SJT), and the Combat Ready Clamp] showed the ability to achieve vascular occlusion.
