The Effects of Perioperative Autotraiisfusion on Postoperative Blood Transfusion in Cardiopulmonary Bypass Patients

Abstract

Objective: It is known that cardiopulmonary bypass has negative effects on patient blood values during cardiac surgeries. In our study, we aimed to investigate the effects of acute normovolemic hemodilution in patients who underwent coronary artery bypass surgery. Material and Method: In our study we included a total number of 40 patients who underwent elective coronary arter)' bypass grafting using a cardiopulmonary bypass in Siyami Ersek Chest and Cardiovascular Surgery Training and Research Hospital. Male, and female patients whose preoperative hematocrit values ivere ≥36% and, ≥ 40% were included in our study. Results: Group 1 (n=20) consisted of 18 male and 2 female patients with a mean age of 54.7±6 years who received autotraiisfusion. Control group (Group 2: n=20), consisted of 17 male, and 3 female patients with a mean age of 58.1±9 years. Hematocrit values were found to be lower in the autotraiisfusion group during the cardiopulmonary bypass procedure than those of the control group, and higher at the end of the operation and at the discharge from the hospital (p<0.05). Conclusion: In our study, if there were no additional comorbidities in patients who will undergo open heart surgery, blood drawn for autotraiisfusion during the perioperative period reduced the need for allogeneic blood during the postoperative period. Based on all these factors, we think that autotraiisfusion in cardiac surgery can be performed safely because of its positive effects on hemodynamics, metabolic and functional outcomes.
