Intra-operative cell salvage for cesarean delivery: a retrospective study using propensity score matched analysis.

ABSTRACT: BACKGROUND:Obstetric hemorrhage is a major cause of maternal death during cesarean delivery. The objective of this retrospective observational study was to evaluate the efficacy and safety of intra-operative cell salvage (IOCS) in cesarean section. METHODS:We included a total of 361 patients diagnosed with central placenta previa who underwent cesarean section from May 2016 to December 2018. In this study, 196 patients received autologous transfusion using IOCS (IOCS group) and 165 patients accepted allogeneic blood transfusion (ABT group). Propensity score matched analysis was performed to balance differences in the baseline variables between the IOCS group and ABT group. Patients in the IOCS group were matched 1:1 to patients in the ABT group. RESULTS:After propensity score matching, 137 pairs of cases between the two groups were successfully matched and no significant differences in baseline characteristics were found between the IOCS group and ABT group. Patients in the IOCS group were associated with significantly shorter length of hospital stay, compared with ABT group (8.9?±?4.1 days vs. 10.3?±?5.2 days, t?=?-2.506, P?=?0.013). The postoperative length of hospital stay was 5.3?±?1.4 days for patients in the IOCS group and 6.6?±?3.6 days for those in the ABT group (t?=?-4.056, P?
