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. ⋯ 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.
