Maternal and neonatal outcomes of preeclamptic and normotensive women who underwent cesarean section under spinal anesthesia: A systematic review and meta-analysis

Abstract

Background: preeclampsia is very challenging for anesthetists due to the heterogeneous clinical spectrum of the disease characterized by hypertension, risk of hypotension, high risk of aspiration, and difficult airway. Therefore, the Meta-Analysis is intended to provide evidence on maternal and neonatal outcomes of preeclamptic parturient. Methods: A comprehensive strategy was conducted in PubMed/Medline, Science Direct, and Cochrane from January 2000 to May 2020 without language restriction. The Heterogeneity among the included studies was checked with forest plot and I2 test. Observational and experimental studies reporting maternal and neonatal outcomes among preeclamptic and normotensive women were included. Results: The Meta-Analysis revealed that pooled incidence of hypotension was reduced by thirty-eight percent in preeclamptic as compared to normotensive parturient, RR = 0.62(95% confidence interval (CI): 0.52 to 0.75). Conclusion: The Meta-Analysis revealed that the incidence of hypotension was lower in preeclamptic women when compared to normotensive women. The included studies were low to a very low quality of evidence which entails further randomized controlled trials. Registration: This systematic review and meta-analysis was registered in research Registry (UIN of reviewregistry1068).
