Combined use of crystalloid preload and low dose spinal anesthesia for preventing hypotension in spinal anesthesia for cesarean delivery: a randomized controlled trial.

Background And Objective: Spinal anaesthesia for caesarean section is commonly associated with hypotension and crystalloid preload is widely recommended. Low-dose spinal appears to cause less hypotension. The aim of this study was to investigate whether the combined use of crystalloid preload and low dose spinal anaesthesia might further reduce the rates of hypotension.
