Abstract

Background: Although planned cesarean delivery (PCD) is the mainstay of management for abnormal placentation, some patients still require emergency cesarean delivery (ECD). We aimed to systematically analyze the impact of various modes of delivery on neonatal outcomes. Methods: This study was complied with the PRISMA guidelines and was registered in the PROSPERO (code: CRD42022379487). A systematic search was conducted on Ovid MEDLINE and Embase, Web of Science, PubMed, and the Cochrane databases. Data extracted included gestational age at delivery, birth weight, the Apgar scores at 1 and 5 minutes, numbers of newborns with low Apgar score (<7) at 5 minutes, the rates of neonatal intensive care unit admission, and the rates of neonatal mortality. Results: Fifteen cohort studies met the inclusion criteria, comprising a total of 2565 women (2567 neonates) who underwent PCD (n = 1483) or ECD (n = 1082) for prenatally diagnosed placenta accreta spectrum (PAS) and/or placenta previa (PP). Compared with the ECD group, neonates in the PCD group had significantly higher gestational ages (standardized mean difference [SMD]: 2.20; 95% confidence interval [CI]: 1.25–3.15; P < .001), birth weights (SMD: 1.64; 95% CI: 1.00–2.27; P < .001), and Apgar scores at 1 minute (SMD: 0.51; 95% CI: 0.29–0.73; P < .001) and 5 minutes (SMD: 0.47; 95% CI: 0.25–0.70; P < .001). Additionally, the PCD group had significantly lower rates of neonatal intensive care unit admission (odds ratio [OR]: 0.21; 95% CI: 0.14–0.29; P < .001), low Apgar score at 5 minutes (OR: 0.27; 95% CI: 0.11–0.69; P = .01), and neonatal mortality (OR: 0.13; 95% CI: 0.05–0.33; P < .001). Conclusion: When pregnancies are complicated by abnormal placentation, PCD is linked to noticeably better neonatal outcomes than emergent delivery.
