AbstractOf 22 patients undergoing repeat open-heart surgery through a previous median sternotomy wound 11 were randomised to receive the serine proteinase inhibitor aprotinin in high dosage (about 700 mg intravenously from the start of anaesthesia to the end of operation, depending on the length of the surgical procedure). Their mean blood loss was 286 ml compared with 1509 ml in the 11 control patients (p less than 0.001), and mean haemoglobin losses were 8.3 g and 78 g, respectively (p less than 0.001). Blood transfusion requirements were eightfold higher in the control group than in the aprotinin group, 7 of whom received only the single unit of their own blood taken before cardiopulmonary bypass.
