简介：AbstractEnhanced recovery after cesarean (ERAC) delivery is an evidence-based, multi-disciplinary approach throughout pre-, intra-, post-operative period. The ultimate goal of ERAC is to enhance recovery and improve the maternal and neonatal outcomes. This review highlights the role of anesthesiologist in ERAC protocols. This review provided a general introduction of ERAC including the purposes and the essential elements of ERAC protocols. The tool used for evaluating the quality of ERAC (ObsQoR-11) was discussed. The role of anesthesiologist in ERAC should cover the areas including management of peri-operative hypotension, prevention and treatment of intra- and post-operative nausea and vomiting, prevention of hypothermia and multi-modal peri-operative pain management, and active pre-operative management of unplanned conversion of labor analgesia to cesarean delivery anesthesia. Although some concerns still remain, ERAC implementation should not be delayed. Regular assessment and process improvement should be imbedded into the protocol. Further high-quality studies are warranted to demonstrate the effectiveness and efficacy of the ERAC protocol.

简介：AbstractBackground: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 < 0.001). The post-operative hemoglobin level in the IOCS group and ABT group was 101.3 ± 15.4 and 96.3 ± 16.6 g/L, respectively, which were significantly different (t= 2.615, P= 0.009). Allogeneic red blood cell transfusion was significantly lower at 0 unit (range: 0–11.5 units) in the IOCS group when compared with 2 units (range: 1–20 units) in the ABT group (P < 0.001).Conclusions:This retrospective observational study using propensity score matched analysis suggested that IOCS was associated with shorter length of postoperative hospital stay and higher post-operative hemoglobin levels during cesarean delivery.
