ABSTRACT
Purpose: To investigate the in vitro effect of human albumin (HA) and fresh frozen plasma (FFP) added to prime solution on platelet functions and coagulation in patients undergoing cardiopulmonary bypass (CPB) surgery. Methods: Sixty consecutive patients receiving elective cardiopulmonary bypass with open heart surgery were enrolled in the study. Patients were divided into three equal groups. Group 1: with 2 units of fresh frozen plasma added to prime solution. Group 2: With 100 cc 25% human albumins added to prime solution. Group 3: (control group) with no FFP or HA added to prime solution. PFA-100 platelet function analyzer and platelet aggregation tests were investigated pre-induction, during and after CPB and on the 1st day postoperatively. Results: Postoperative drainage was significantly higher in groups 2 and 3 compared to Group 1 (p<0.01). The compromise in platelet functions in groups 1 and 2 improved, while in Group 3 preoperative values were not attained at the end of the 1st day postoperatively. There was a significant difference between groups 2 and 3 in terms of erythrocyte suspension (ES) used in intensive care (p<0.01). Greater hemorrhage occurred in the postoperative period in Group 3 and more ES was used. In addition, lengths of stay in intensive care differed significantly between groups 2 and 3 (p<0.01). Conclusion: FFP used in CPB causes reduced drainage in the postoperative period and necessitates less use of blood and blood products.
