Abstract

In February, 1975, a prospective, randomized study of 75 patients undergoing major gynecologic surgery was undertaken. Patients were randomly assigned to three groups regardless of diagnosis and surgery contemplated. Coagulation studies were performed preoperatively and postoperatively in a control group, a receiving 2,000 U heparin/12 hr subcutaneously, and a third group receiving 5,000 U/12 hr via the same route. There was a statistically significant increase noted in fibrin degradation products in the group treated with 5,000 U heparin/12 hr as compared to the control group. Excessive bleeding intraoperatively or postoperatively was not encountered.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
