Aprotinin reduces bleeding after off-pump coronary artery bypass surgery: 002
Introduction: Aprotinin is an antifibrinolytic agent which reduces blood loss after cardiac surgery under CPB . Only one study has evaluated the effect of aprotinin during off-pump (OPCAB) surgery. The aim of this study was to evaluate the efficacy of aprotinin in reducing blood loss after OPCAB.
Method: A retrospective study based on our prospective database compared 40 patients operated on before the routine use of aprotinin (Group O) to 40 patients who received a full dose of aprotinin (Group A). Post operative blood loss, transfusion rate and troponin levels were compared between the 2 groups. 90% of the patients received aspirin until the day of surgery. During operation, patients received 300UI/kg of heparin and complete reversal with protamine at the end of surgery. Packed red blood cells were transfused when haemoglobin concentration was less than 80 g L−1. Groups were compared with t test or Χ2 test when appropriate. Results are given as mean ± SD.
Results: Aprotinin significantly reduces blood loss but not transfusion. Main results are summarized in the table.
Discussion: Aprotinin significantly reduces blood loss after OPCAB surgery. Using aprotinin with a full dose of heparin did not increase postoperative values of troponin.
