Clinical aspects of DIC--disseminated intravascular coagulation.
1.286 patients were diagnosed as DIC, among 123.231 patients who were admitted in the 285 departments of the university hospitals in Japan, in 1992. The incidence of DIC was high in acute promyelocytic leukemia, fulminant hepatitis, abruptio placentae, acute respiratory distress syndrome, and sepsis. In cases of DIC, bleeding tendency due to consumption coagulopathy is most important, but organ dysfunction due to circulatory disturbances by development of multiple thrombi is also noteworthy. As a whole, DIC may be divided in two types. The first type is cases of DIC with severe bleeding symptoms. However, except cerebral hemorrhage, organ dysfunction is rare in these cases. These cases may be called as "fibrinolysis-dominant DIC", because hemostatic thrombi as well as thrombi which cause organ dysfunction by circulatory disturbances are rapidly removed by abnormally enhanced fibrinolysis. The second type involves cases of DIC with severe organ dysfunction. Bleeding symptoms in these cases are usually not severe. These cases may be called as "coagulation-dominant DIC". The most typical causative disease of the fibrinolysis-dominant DIC is acute promyelocytic leukemia. The most typical causative disease of the coagulation-dominant DIC is sepsis. The presence of causative disease of DIC, elevation of FDP, and depletion of platelet count are most important to diagnose DIC. In the treatment of DIC, removal of cause of DIC, administration of heparin to protect further development of multiple thrombi, and replacement of platelets in cases of acute leukemia are most important.
