Main findings

ICS has been shown to reduce the need for homologous transfusion during cesarean section in patients at high risk of haemorrhage2,12. The autotransfusion rate has been reported as 21–100% depending on the characteristics of the women who benefit from ICS13,14. In our study, 33.1% of patients were reinfused. We found 3 indications that were predictive of autotransfusion: placenta accreta, uterine fibroids, and postoperative bleeding. The predictive bleeding threshold for autotransfusion identified in the ROC analysis was 936 mL.
