Abstract: Objective To observe the effect of intraoperative cell salvage (ICS) on allogeneic blood transfusion and economic benefits of cesarean women. Methods A total of 369 cesarean women admitted to the obstetrics department of a top three hospital from January 2016 to September 2018 were retrospectively collected, including 252 cases in the ICS group and 120 cases in the control group (allogeneic blood transfusion). According to the amount of bleeding during the operation, the two groups of cesarean women were divided into subgroups. The maternal allogeneic blood transfusion (red blood cells, plasma, platelets, and cryoprecipitation) and economic benefits (time spent in hospital, blood transfusion costs, and pre-transfusion examinations) were compared in each subgroup. Results There was no significant difference in the general data between two groups (both P>0.05). Compared with the control group, the amount of allogeneic red blood cells was significantly reduced in the subgroups of the ICS group. Allogeneic red blood cells and allogeneic plasma usage are significantly reduced in the blood loss less than 1600 mL subgroups of the ICS group (all P<0.05). Compared with the control group, the blood transfusion cost of each subgroup in the ICS group with blood loss ≥800 mL was significantly reduced (all P<0.05). There were no significant differences in the length of hospital stay and the cost of pre-transfusion examinations in each subgroup between the two groups (all P>0.05). Conclusion ICS can save the use of allogeneic red blood cells and allogeneic plasma in cesarean section, reduces the cost of blood transfusion, and has good economic benefits.
