Relationship Between Blood Product Transfusion and Post-operative Prognosis in Children With Pediatric Open Heart Surgery by Cardiopulmonary Bypass / 中国循环杂志

ABSTRACT

Objective: To explore the relationship between intra-operative blood product transfusion and post-operative prognosis in children with pediatric open heart surgery by cardiopulmonary bypass (CPB). Methods: A total of 1028 consecutive pediatric patients received the open heart surgery by CPB in our hospital were retrospectively studied. Uni- and multivariate Logistic regression analysis were conducted to analyze the relationship between intra-operative blood product transfusion and post-operative in-hospital death and complication rates. Results: There were 45/1028 (4.4%) of patients died, 143 (13.9%) with low cardiac output syndrome, 43 (4.2%) received dialysis, 26 (2.5%) with sustained pulmonary failure, 17 (1.7%) with infection, and 28 (2.7%) developed neurologic complications. Multivariate Logistic regression analysis indicated that duration and the lowest temperature of CPB, 24-hour post-operative pediatric risk of mortality (PRISM-III) score and intra-operative transfusion amount of RBC > median (20.3 ml/kg) were the independent risk factors for post-operative in-hospital death. Congenital heart disease (CHD) with pre-operative cyanosis, duration of CPB, 24-hour post-operative PRISM-III score, 6-hour post-operative mediastinal drain loss and intra-operative transfusion amount of RBC > 20.3 ml/kg were the independent risk factors for post-operative complication occurrence. Conclusion: Large volume of RBC transfusion in the open heart pediatric surgery with CPB may increase the risk of post-operative in-hospital death and complication occurrence, reducing RBC transfusion might be improving the post-operative prognosis in CHD patients.
