UNIVERZITA KARLOVA Lékařská fakulta v Hradci Králové Acquired fibrinogen deficiency in severe trauma patients and its early detection Josef Škola Summary Doktorský studijní program Chirurgie Hradec Králové 2023 This thesis deals with developing and early diagnostics of acquired fibrinogen deficiency in patients with severe trauma. Fibrinogen is an essential glycoprotein of the coagulation system, which is converted by thrombin into insoluble fibrin, the fundamental component of a blood clot, in the final stage of blood coagulum formation. Trauma-induced coagulopathy is a complex disorder of blood coagulation resulting from extensive tissue damage, traumatic shock, activation of the sympathoadrenal system, dysregulation of fibrinolysis, as well as loss of coagulation factors through bleeding, consumption or dilution of remaining dilutions. Hypothermia, acidosis, hypocalcemia, or preexisting factors on the patient's side (e.g., anticoagulant or antiplatelet therapy) also contribute to impaired haemocoagulation. Acquired fibrinogen deficiency (hypofibrinogenemia) is vital in the early phase of trauma-induced coagulopathy. Fibrinogen is the first of the coagulation factors to achieve a clinically significant decrease in plasma concentration. Hypofibrinogenemia is associated with the magnitude of blood loss, the...
