Comparison of prophylactic infusion of ephedrine and phenylephrine during Cesarean section under spinal anaesthesia

Spinal anaesthesia for caesarean delivery may be associated with hypotension and fetal acidosis. Prophylactic infusion of phenylephrine (PE) immediately after the induction of anaesthesia appears to be a more effective approach than administration of ephedrine to reduce the incidence, frequency and severity of hypotension. Furthermore, PE appears to be associated with better fetal acid-base status than is ephedrine.
