Aim: There is no consensus between different clinics about the usage of remaining blood in venous reservoir during coronary bypass surgery with cardiopulmonary bypass operation. Our prospective study, we aimed to research effects of the use of remaining blood in venous reservoir after cessation of cardiopulmonary bypass for patients undergoing coronary bypass surgery on drainage, need for blood and blood products, postoperative infection complications, duration of intensive care unit and total hospitalization time.
Material and Methods: Forty six patients undergoing coronary bypass surgery were examined prospectively between June 2011 and December 2011. Patients were divided into two groups. In group 1, remaining venous reservoir blood after cessation of extracorporeal circulation was used intraoperatively but in group 2 it was not used. Two groups were compared for amount of drainage, need of blood and blood products, intensive care unit stay, postoperative infectious complications and discharge time.
Results: It was detected that mediastinal drainage amount for group 1 and group 2 respectively were 521±263 ml/423±258 ml (p=0.211), need blood and blood product were 0.8±1.0 u/1.2±1.2 u (p=0.228), intensive care unit stay were 22.9±1.5 hours/24.5±9.1 hours (p=0.378) and discharge time were 4.9±1.0 days/5.5±1.8 days (p=150). Hospital mortality and blood transfusion related infectious complications were not detected for patients included in the study.
Conclusions: In our study, we detected that the use of remaining venous reservoir blood after cardiopulmonary bypass does not increase blood drainage as thought, however it does not lead significant decrease to need blood and blood products transfusion.
