Crystalloids versus colloids versus hypertonic saline co-load during spinal anesthesia: which is more effective?

Abstract

Spinal anesthesia is very commonly accompanied by hypotension due to sympathetic blockade, which leads to vasodilation. There is an ongoing debate concerning pre-load versus co-load and also the best suitable type of fluid to be given, including hypertonic saline (HS). We conducted this study to compare the efficacy of the three solutions, crystalloids vs. colloids vs. hypertonic saline co-load during spinal anesthesia.
