Abstract: Objective To retrospectively analyze the use of intraoperative cell salvage (ICS) in our hospital in recent years, and to analyze the indication to ICS during cesarean section. Methods A total of 1 108 women with cesarean section in our hospital from January 2018 to December 2019 were included, 673 cases in the reinfusion group and 435 cases in the non-reinfusion group. The basic information and clinical data between two groups were analyzed by SPSS 23.0. Results The reinfusion rates of ICS between Jan. 2018 and Dec. 2019 were 60.74%. In the reinfusion group, there was a linear correlation between the amount of blood lost and reinfusion during the operation. There were significant differences in placenta previa, placenta accreta, placental abruption, scarred uterus, preeclampsia and the amount of blood lost between the two groups (P<0.05). Logistic regression analysis showed that placenta previa, placental accreta, placental abruption and scarred uterus can increase the risk of autologous blood transfusion. Conclusion Placenta previa, placental accreta, placental abruption and scarred uterus are indications for autologous blood transfusion. ICS is recommended for cesarean section in these pregnant women.
