Randomized Controlled Trial Clinical TrialThe effect of tranexamic acid on local and plasma fibrinolysis during total knee arthroplasty.
The aim of the present study was to investigate aspects of coagulation and fibrinolysis during knee arthroplasties in order to find out. 1. whether an increased fibrinolysis is correlated to an increased blood loss 2. whether there is a difference in markers for coagulation and fibrinolysis in peripheral venous blood compared to those in blood from the wounds 3. whether the administration of tranexamic acid modifies the fibrinolytic response. Twenty-four patients were included. Twelve patients were given tranexamic acid intravenously at the end of the operation. ⋯ We found no direct correlation between the degree of fibrinolysis and blood loss. The administration of tranexamic acid reduced fibrinolysis in the wounds but not in peripheral venous blood. The postoperative blood loss was reduced by half.
