Postoperative blood loss in patients undergoing coronary artery bypass surgery after preoperative treatment with clopidogrel. A prospective randomised controlled study

Abstract

Continuation of clopidogrel until the day of surgery induces significantly more postoperative blood loss and increases significantly the total requirements of homologous blood products and FFP transfusion after surgery. The blood loss and the use of blood products in the group that stopped at 3 days preoperatively were similar to that of the group that stopped at 5 days preoperatively.
