The leading cause of preventable death in trauma is uncontrolled bleeding. Some of these deaths may be secondary to the Acute Coagulopathy of Trauma, which is present in 30% of patients on admission to hospital. In recent years, Damage Control Resuscitation has been developed, which aims to give a hemostatic resuscitation and avoid deaths caused by bleeding. ⋯ Several studies have reported that early transfusion of all blood products, with a ratio close to 1:1, may be associated with lower mortality and less requirements of total transfusions in trauma patients at risk of massive bleeding and massive transfusion. These findings must be corroborated in randomized controlled trials, along with determining the optimum ratio between blood products. In stable patients, a restrictive transfusion strategy is safe and appropriate.
