Objectives: The use of blood and blood products, which is a major complication, significantly increases the duration of stay in intensive care and hospitalization, as well as hospital costs on open heart surgery. In our study, we aimed to investigate the relationship between postoperative early bleeding, blood and blood product use in coronary artery bypass grafting (CABG) surgery under cardiopulmonary bypass (CPB). Methods: In this study, 843 patients who underwent consecutive CABG operation between May 2012 and March 2014 were included. The patients were classified into three categories according to their body mass index (BMI); weak group (BMI ?19 kg/m2), normal weight group (BMI 20-29 kg/m2) and obese group (BMI ?30 kg/m2). Preoperatively; age, gender, height, weight, diabetes mellitus (DM), hypertension, hyperlipidemia, chronic obstructive pulmonary disease (COPD), preoperative myocardial infarction, left ventricular ejection fraction (LVEF), mean hemoglobin and platelet values, Intraoperatively; cross clamp time, cardiopulmonary bypass time, total duration of the operation, amount of cardioplegia given, number of grafts used in coronary bypass. Postoperatively; the total amount of blood used, drainage amount, given vasopressor treatment, given positive inotropic support, intraaortic balloon pump usage, intubation duration, intensive care stay, hospital stay, bleeding-related re-exploration and mortality of all patients were examined. Results: It was observed that more blood transfusions performed in patients with low and normal weight compared to the obese group (11.22±2.85 ml/kg, p=0.011). Also in patients with low and normal weight compared to the obese group more blood loss was observed (7.12±1.87 ml/kg, p=0.017). Conclusion: In our study, in accordance with the general opinion of previous studies, we found that patients with high BMI had lower postoperative blood loss and blood use than patients with low BMI. Keywords: Body mass index, blood transfusion, coronary bypass surgery
