Disseminated intravascular coagulation

Under the action of certain pathogenic factors, coagulation factors and platelets are activated, a large amount of procoagulant substances enter the blood, thrombin increases, and extensive microthrombosis is formed in the microcirculation. A large amount of coagulation factors and platelets are consumed during microthrombosis, and secondary fibrinolytic function is enhanced, leading to clinical manifestations such as bleeding, shock, organ dysfunction, and hemolytic anemia. This pathological process is called DIC.
