title: Haemostasis management of massive bleeding.
abstract: Trauma-induced coagulopathy (TIC) is a frequent complication of severely injured patients. The etiology of TIC is complex. Contributing factors include overwhelming generation of thrombin and activated protein C, consumption of coagulation factors and platelets, hyperfibrinolysis, and dilution of clotting factors through administration of fluids. In addition, hypothermia and shock-associated metabolic acidosis augment the clotting dysfunctions. The occurrence of TIC has been shown to be an independent risk factor for death after trauma warranting aggressive treatment. On admission to the emergency room patients with massive blood loss should be employed on basis of clinical and diagnostic variables to identify patients at high risk of coagulopathy. Patients at high risk should be treated with tranexamic acid (1 g bolus followed by 1 g/8 h), and critical factor and platelet deficiencies should be corrected by transfusion of factor concentrates and platelet concentrates. In addition, plasma should be administered in a 1:1 ratio with red cells. The use of recombinant factor VIIa should be considered if major bleeding persists despite best-practive use of blood products.
