The prognosis of traumatized hemorrhages is correlated with the nature of transfusion therapy: a 50% reduction in mortality for an early and massive supply of plasma, and 20% for an early and massive supply of platelets. However, this strategy encounters logistical difficulties, particularly in a context of collective emergency (attacks). The use of whole blood, widely documented by the Armed Forces, improves the availability of plasma and platelets, and simplifies handling by the various actors in the chain.

T-STORHM is a randomized, controlled, parallel clinical trial.This study tests non-inferiority of whole blood transfusion therapy in the management of coagulopathy in patients with acute traumatic hemorrhage.

In recent years, terrorist attacks have confronted the investigator's healthcare system with a massive influx of victims of war weapon injuries. This new fact makes the efficiency of transfusion therapy crucial: hemorrhage is the leading cause of death from weapons of war, and the high number of victims of each attack changes the logistical approach.

The logistical problems with transfusion therapy, including red blood cell (PRBCs), plasma and platelet concentrates, are the speed of delivery and availability. Using whole blood is a pragmatic solution to overcome these problems. This solution has been used for many years by the French Army to ensure platelet transfusion in traumatic hemorrhages

The hypothesis of the T-STORHM study is that the use of whole blood is a solution in a context of civil trauma not effective less than component therapy (PRBCs, plasma and platelet concentrates) in the management of coagulopathy in patients admitted to hospital for traumatic hemorrhage.

Inclusion Criteria:
