Lipid Emulsion for Reversal of Spinal Anesthesia in Ambulatory Surgery

Ambulatory surgery places high demands on anesthetic technique. rapid onset and offset of anesthesia, rapid recovery of protective reflexes, mobility and micturition, are required. Since the inception of ambulatory surgery, the favored anesthetic technique has been general anesthesia with short-acting drugs. Concerns about the time to perform spinal anesthesia and the risks of prolonged motor block and urinary retention have limited its use. Alpha-blockers, lavage fluids for epidural space, insulin, and intravenous lipid emulsions, are still being discussed to shorten and reverse adverse effect of different LAs used for spinal anaesthesia, hence we will evaluate the effectiveness of intravenous lipid emulsion for reversing the neural blockade of spinal anaesthesia in patients undergoing ambulatory surgery.
