Abstract: Objective To retrospectively analyze the use of intraoperative cell salvage （IOCS） and allogeneic blood transfusion in a tertiary hospital, and to evaluate effect of IOCS on allogeneic blood transfusion and its application in cesarean section. Methods A total of 8188 cesarean section cases from January 2015 to December 2018 were collected in a tertiary hospital.Allogeneic blood usage in non-implementation period （IOCS not applied from January 2015 to August 2016） was compared with that in implementation period （IOCS applied from September 2016 to December 2018）. The monthly IOCS use rate was compared with autologous blood transfusion rate during surgery in the implementation period. Results The average number of allogeneic red blood cell units and dose of allogeneic plasma during implementation period were significantly lower than those during non-implementation period （P<0.05）. During implementation period, the average age, placenta praevia, previous cesarean section rate, and IOCS usage increased year-over-year in 2016, 2017, and 2018, but the reinfused rate of IOCS did not change. Conclusion In recent years, the application of IOCS in cesarean section has reduced the demand for allogeneic blood transfusion, and there is still room for improvement in clinical indication selection.
