dc.description.abstractTitle: An audit of the intraoperative usage of blood products in patients undergoing cardiac surgery on cardiopulmonary bypass. Background: Transfusion of blood products is increasingly recognised as an independent predictor of poor outcome after cardiac surgery. The study aims to audit blood transfusion usage in a cardiothoracic unit, at a tertiary academic centre. Methods: A descriptive, retrospective, contextual audit. A consecutive convenience sampling method was used. One hundred and twenty-­two adult patients who underwent their first elective cardiac surgery on cardiopulmonary bypass were enrolled. Results: The mean age of the population studied was 46.7 (16.2) years. Patients were predominantly male (60.7%). The mean (SD) body mass index was 21.4 (5.6) kg/m2. Their mean (SD) preoperative haemoglobin and platelet count was 12.8 (2.3) g/dL and 274.4 (121.9) 109/L respectively. Following a clear fluid prime cardiopulmonary bypass technique, with a median (IQR) priming volume of 1500 (1000 -­ 2000) ml, the first mean (SD) haemoglobin on cardiopulmonary bypass was 8.9 (1.6) g/dL. Overall, 110 (90.2%) patients received donor blood products. Eighty-­five (77.3%) patients received red blood cells,103 (93.6%) fresh frozen plasma, and 35 (31.8%) platelet transfusion. A total of 255 red blood cell, 225 fresh frozen plasma and 37 platelet units were transfused. The cell salvage technique was used in 94 (77.0%) patients. The median (IQR) volume of salvaged blood was 535 (250– 754) ml. Conclusion: A high rate of homologous blood product transfusion was found in patients undergoing cardiac surgery in the study.en_ZA
