Abstract
The changes in coagulation and fibrinolytic activity in 22 patients with oral cancer undergoing extensive surgical procedures were studied. The patients were divided into two groups: group I patients suffered blood loss of less than 2,000 mL and group II patients had blood loss of more than 2,000 mL. The platelet count decreased significantly during surgery, at the end of surgery and on the 1st postoperative day in both groups. Fibrinogen was decreased during and at the end of surgery in both groups, but increased significantly on the 3rd postoperative day and reached about two times the preoperative levels on the 7th postoperative day. Fibrin degradation products increased significantly after surgery and reached the maximum value on the 1st postoperative day in both groups. Plasmin inhibitor complex and plasminogen increased significantly on the 3rd and 7th postoperative days. There was no clear evidence regarding the influence of blood loss on coagulation and fibrinolytic factors except for platelets. It was concluded that coagulation and fibrinolysis are enhanced between the 3rd and 7th postoperative days.
