Abstract:
Objective:To identify the risk factors for massive blood transfusion in pediatric living donor liver transplantation.Methods:The medical data of children underwent living donor liver transplantation in our hospital from April 2006 to April 2019 were retrospectively collected.Massive transfusion was defined as the administration of red blood cells > 1 fold of the total blood volume (70 ml/kg) during operation.Patients were assigned to massive transfusion group and non-massive transfusion group according to the volume of blood transfused during operation.Binary logistic regression analysis was used to identify the risk factors for massive blood transfusion during living liver transplantation.Results:A total of 95 pediatric patients were enrolled in this study, with 18 cases in massive transfusion group and 77 cases in non-massive transfusion group.The incidence of massive blood transfusion was 19% during operation.The results of logistic regression analysis showed that preoperative survival status of " hospitalization" ( OR=49.816, 95% CI 2.945-842.59, P=0.007), increased serum Cr concentrations ( OR=1.046, 95% CI 1.007-1.086, P=0.021), increased Pediatric End-Stage Liver Disease (PELD) or Model for End-Stage Liver Disease (MELD) score ( OR=1.215, 95% CI 1.046-1.411, P=0.011) and prolonged operation time( OR=1.623, 95% CI 1.133-2.327, P=0.008) were the independent risk factors for intraoperative massive blood transfusion in living donor liver transplantation, while increased recipient weight ( OR=0.856, 95% CI 0.761-0.962, P=0.009) was a protective factor for intraoperative massive blood transfusion. Conclusions:Preoperative survival status of " hospitalization", increased PELD or MELD score and prolonged operation time are independent risk factors, while increased pediatric weight is a protective factor for massive blood transfusion in pediatric living donor liver transplantation.
