Analysis of perioperative blood transfusion and the influencing factors of mass-transfusion in patients underwent heart transplantation

Abstract

Objective To provide references for clinical prediction of blood preparation and blood consumption, as well as the influencing factors of mass-transfusion by analyzing the perioperative blood transfusion in patients underwent heart transplantation. Methods The blood transfusions of 44 patients with heart transplantation completed in the Department of Cardiac Surgery of our hospital from March 2014 to January 2022 were retrospectively collected. Patient information included age, gender, preoperative diagnosis, relevant medical history, history of cardiac surgery, and history of antithrombotic medication. The risk factors of perioperative red blood cell transfusion in patients with heart transplantation were analyzed by univariate analysis method and multivariate logistic regression method. Results All 44(100%) heart transplant patients received blood components: the average transfusion units of red blood cells was 3.75(0, 7.5) U (72.73%), plasma 1 140 (597.5, 1782.5) mL (97.73%), cryoprecipitate 10(9.5±10) U(88.64%), platelets 1(1, 1.25) therapeutic amount (86.36%). The rate of massive transfusion of red blood cells was 45.45% (20/44). The univariate analysis found that there were significant differences in preoperative use of antithrombotic drugs, blood loss, and cardiopulmonary bypass time between the red blood cell transfusion group≤4 U (n=24) and the red blood cell transfusion group >4 U (n=20) (P<0.05). Multivariate Logistic regression analysis showed that preoperative antithrombotic drug treatment (n=15) was OR 5.900, 95%CI 1.313~26.521(P<0.05) and cardiopulmonary bypass time was OR 1.024, 95%CI 1.000~1.049(P<0.05). Conclusion The perioperative transfusion rate of blood components in cardiac transplant patients was high. The preoperative use of antithrombotic drugs, and prolonged cardiopulmonary bypass are risk factors for massive red blood cell transfusion.
