Hémorragies jonctionnelles: Comprimer le pelvis

UK Combat-Related Pelvic Junctional Vascular Injuries 2008-2011Implications for Future Intervention.

Walker NM et All. - Bone Joint Journal (2013) vol. 95-B no. SUPP 8 13

---------------------------------------------------------------------------------------

L'arrêt d'une hémorragie jonctionnelle est un enjeu majeur. Plusieurs dispositifs ont été récemment proposés.  Il semble que la grande majorité des lésions observées se situent au dessus du ligament inguinal rendant ainsi l'efficacité de dispositif comme le CRoC limité. Le tourniquet abdominal ou le sam junctionnal tourniquet paraissent ainsi au moins théoriquement un meilleur choix si toutefois ils permettent une compression suffisante.

In a recent publication, 4.6% of 6450 Coalition deaths over ten years were reported to be due to junctional bleeding. The authors suggested that some of these deaths could have been avoided with a junctional hemorrhage control device.

Prospectively collected data on all injuries sustained in Afghanistan by UK military personnel over a 2 year period were reviewed. All fatalities with significant pelvic injuries were identified and analysed, and the cause of death established.

Significant upper thigh, groin or pelvic injuries were recorded in 124 casualties, of which 92 died. Pelvic injury was the cause of death in 42; only 1 casualty was identified where death was at least in part due to a vascular injury below the inguinal ligament, not controlled by a tourniquet, representing <1% of all deaths. Twenty one deaths were due to vascular injury between the aortic bifurcation and the inguinal ligament, of which 4 survived to a medical facility.

Some potentially survivable deaths due to exsanguination may be amenable to more proximal vascular control. We cannot substantiate previous conclusions that this can be achieved through use of a groin junctional tourniquet. There may be a role for more proximal vascular control of pelvic bleeding.
