Comparison of Phenylephrine Bolus and Infusion Regimens on Maternal and Fetal Outcomes During Cesarean Delivery: A Systematic Review and Meta-Analysis
US Clinical registry databases were searched. Studies comparing phenylephrine boluses (both therapeutic and prophylactic) with infusion (both fixed- and variable-rate) assessing various feto-maternal outcomes were included. The primary outcome was the incidence of maternal hypotension. Secondary maternal outcomes included the incidence of reactive hypertension, bradycardia, nausea, or vomiting; secondary neonatal outcomes included umbilical arterial pH, partial pressure of oxygen (paO2), umbilical venous pH, fetal acidosis, Apgar Scores at 1 and 5 minutes.
