Disseminated intravascular coagulation (DIC) is a complex clinical syndrome with activation of the procoagulant and fibrinolytic systems along with inhibitor consumption. We discuss regarding the controversies in diagnosis and management of DIC. Bleeding is a more common manifestation of DIC but most of the morbidity and mortality of DIC is due to microvascular thrombosis. Routinely performed tests for DIC such as platelet count and prothrombin time may be normal in chronic DIC. There is no single test that would diagnose DIC, however, estimation of D-dimer appears to be the most sensitive and specific test. Therapy of DIC aims at treating the primary cause. Fresh frozen plasma and platelet concentrates are recommended only in bleeding patients and have the potential risk of adding procoagulant material to the already activated procoagulant system. Role of heparin and antithrombin in patients with sepsis and DIC is discussed.
