Abstract:
Objective To assess the safety and effect of intraoperative cell salvage (ICS) during cesarean section.Methods This was a case-control study in which 60 gravidas who received ICS (ICS group) and 60 gravidas who received allogenic transfusion (control group) during caesarean section in Obstetrics and Gynecology Hospital of Fudan University during January 2014 to December 2016 were enrolled.Subjects in the two groups were matched in age,gestational age,gestational complications (placenta increta,placenta previa,scarred uterine,leiomyomas and anemia) and hemorrhagic volume during cesarean section.Several indicators including complications of transfusion,postoperative recovery,expense of transfusion,as well as the complete blood count and body temperature before and after operation were compared between the two groups.T,rank-sum or Chi-square test was used for statistical analysis.Results (1) No significant difference in age,gestational age,twin gestation,complications,preoperative body temperature,or the volume of hemorrhage or transfusion was observed between the two groups (all P＞0.05).(2) The autotransfusion volume was 385 (161-583) ml in the ICS group.Fifteen cases (20.0％) in the ICS group also received additional transfusions of leukocyte-reduced red blood cell (RBC) suspension,fresh frozen plasma and cryoprecipitate and two cases (3.3％) received additional transfusions of leukocyte reduced RBC suspension and fresh frozen plasma.The two groups showed no significant difference in the cost of transfusion or per-capita transfusion volume of fresh frozen plasma or cryoprecipitate.However,the transfusion volume of leukocyte-reduced RBC suspension was lower in the ICS group as compared with that in the control group [M(P25-P75),1.9 (1.5-4.5) vs 4.1 (2.8-6.2) U,Z=-2.800,P=0.005].(3) There was no significant difference in complete blood count or coagulation function between the two groups before the operation.White blood cell (WBC) counts in the two groups were elevated following operation.Postoperative WBC count in the control group was higher than that in the ICS group,while the levels of RBC and hemoglobin were lower than those in the ICS group following operation (all P＜0.05).(4) No amniotic fluid embolism was reported in the two groups.Only one case of rash was reported in the ICS group,which was fewer than the transfusion reactions occurred in the control group [1.7％ (1/60) vs 13.3％ (8/60),x2=5.886,P=0.016].(5) The two groups showed no significant difference in preoperative temperature,the highest temperature within three days after operation or incision healing.Compared with the patients in the control group,those in the ICS group had shorter hospital stay [(4.7± 1.1) vs (6.3 ±1.8) d,t=3.341,P＜0.05].Conclusion ICS is a safe and effective measure for gravidas at higher risk of hemorrhage during cesarean section.
