Comparison between colloid preload and crystalloid co-load in cesarean section under spinal anesthesia: A randomized controlled trial

Background Hypotension is a common problem during spinal anesthesia for cesarean delivery. Intravenous fluid loading is used to correct preoperative dehydration and reduce the incidence and severity of hypotension. Different fluid regimens have been studied but colloid preload and crystalloid co-load have not been compared.
