Evaluation of antihypotensive techniques for cesarean section under spinal anesthesia: Rapid crystalloid hydration versus intravenous ephedrine.

Background: Spinal anesthesia is a preferred technique over general anesthesia for cesarean delivery. It avoids maternal airway related complications, aspiration and neonatal depression. However hypotension following spinal anesthesia can lead to decrease in uterine blood flow and neonatal hypoxia.
