Abstract: Objective To investigate the transfusion status of pediatric orthopaedic operation, so as to provide basis evidence for clinical blood protection in pediatric orthopaedic surgery. Methods A total of 7 217 children undergoing orthopedic surgery in our hospital from October 2015 to September 2018 were enrolled. The age, the number of blood transfusion cases, the infusion volume of blood components were collected and statistically analyzed. Results The rate of perioperative transfusion was higher in 2-4-year-old preschool children (P<0.05), and the transfusion proportion was higher in fracture and congenital malformation groups （P<0.05）. Except for developmental hip dysplasia （DDH）, there were significant differences in the number of surgical cases and transfusion rate among different age groups, and there was a certain correlation with age. There were significant differences in the total number of transfusions and the per capita transfusion volume of red blood cells and plasma among different diseases （P<0.05）. Conclusion The analysis of perioperative transfusion for pediatric orthopaedic diseases is helpful to improve transfusion technology in our hospital.
