[Procoagulant hemostatic dressings and hemorrhages]

When faced with a hemorrhage, there are many ways to achieve hemostasis. War medicine and terrorist attacks have taught us the wide use of the tactical tourniquet since hemorrhagic injury is the leading cause of death, mainly in pre-hospital care. The existence of hemorrhagic areas not accessible to tourniquets and the possibility of conversion of a tourniquet by other non-ischemic local hemostasis means have demonstrated the relevance of compression by internal or external packing. Procoagulant hemostatic dressings have progressed in their efficacy over four generations. History and development.
