PurposeWe investigated the impact of anesthesia mode on perinatal outcomes in patients with placenta accreta spectrum (PAS) undergoing cesarean delivery and identified factors associated with adverse perinatal events.MethodsThe multicenter retrospective analysis was conducted in patients with PAS who delivered at three medical centers. Patients were classified according to whether they received general anesthesia (GA) or neuraxial anesthesia (NA). We compared the basic clinical characteristics of patients in the pre-propensity score matching (PSM) and post-PSM cohorts and identified factors associated with a high risk of adverse maternal outcomes.ResultsThis study included a total of 425 patients, with 307 (72.2%) in the GA group and 118 (27.8%) in the NA group. After PSM, 162 patients were identified for analysis. In the post-matched cohort, the NA group exhibited shorter total operation time (P = 0.030) and postoperative length of hospital stay (P = 0.037). Additionally, the NA group experienced lower intraoperative blood loss (P < 0.001) and received fewer units of transfused packed red blood cells (PRBC) (P < 0.001). Multivariate logistic regression analysis indicated that GA (P < 0.001), emergency cesarean delivery (P = 0.010), vascular lacunae within the placenta (P < 0.001), hypervascularity of uterine-placental margin (P = 0.002), hypervascularity of the cervix (P = 0.014), and balloon placement in the abdominal aorta (P < 0.001) were associated with a high risk of adverse maternal events.ConclusionIn comparison to GA, cesarean delivery with NA in PAS patients appears to be associated with reduced intraoperative blood loss, PRBC transfusion, operating duration, and postoperative hospital stay.© 2024.
