[Hemostasis disorders in cancer patients with massive intraoperative blood loss].

The hemostasis system was examined before, during, and after surgery in 130 patients with blood loss from 50 to more than 200% total circulatory volume. Blood loss caused deep changes in the hemostasis system, presenting as acute and subacute syndrome of different hypocoagulation degree in parallel with fibrinolysis activation of different intensity, or as hemodilution coagulopathy, or combination of both. Laboratory signs of acute DIC syndrome anticipate its clinical manifestation, which allows rapid correction of the detected disorders and prevention of severe hemorrhages. A complex of methods for rapid diagnosis of coagulopathic hemorrhages is developed. Various approaches to the treatment of DIC syndrome during and after surgery were used in patients with massive blood loss.
