Comparative Study Among Ephedrine, Norepinephrine and Phenylephrine Infusions to Prevent Spinal Hypotension During Cesarean Section. A Randomized Controlled Double-Blind Study

摘要

Background: Spinal anesthesia is the recommended technique in elective cesarean sections. Usage of vasopressors is more widely accepted as an effective method for decreasing postspinal hypotension than fluid loading. However, the ideal vasopressor to prevent spinal hypotension during cesarean section has been a subject of much debate. It should maintain maternal blood pressure and placental perfusion, with minimal adverse effect on fetus and mother.
