The preoperative characteristics and laboratory variables of the two groups were similar (p > 0.05). The amount of additional fluid given during CPB, the amount of urine and haemofiltrate removed by the patients, intraoperative bleeding drainage rate, postoperative platelet and erythrocyte values, need for intracardiac defibrillation, need for inotropic support and intra-aortic balloon pump (IABP) requirement during CPB weaning, duration of postoperative mechanical ventilation support, and duration of intensive care unit (ICU) stay were similar in both groups (p > 0.05). However, intraoperative erythrocyte transfusion rates, postoperative bleeding drainage rates, postoperative erythrocyte transfusion rates, postoperative leukocyte value and length of hospital stay were significantly higher in group 2 (p = 0.000; p=0.006; p = 0.000; p= 0.009; p = 0.037, respectively). Additionally, postoperative haemoglobin and haematocrit values were significantly lower in group 2 (p = 0.034; p = 0.047, respectively).                                                                                                              \r\n                <br \/>     \r\n\t\t\t\t\r\n\t\t\t\t                                                                                                                                                \r\n        <strong>Conclusion:<\/strong>                                                                                                    \r\n                                                                                                                                                    \r\n         As a result of this study, we observed that low prime solution volume vs. high prime solution volume impacts the negative variables of CPB patients.
