Association of the addition of a transversus abdominis plane block to an enhanced recovery program with opioid consumption, postoperative antiemetic use, and discharge time in patients undergoing laparoscopic bariatric surgery: a retrospective study.

Background: Increasing numbers of laparoscopic bariatric surgeries are being performed and enhanced recovery from anesthesia and surgery (ERAS) protocols have been implemented to optimize care for these patients. We evaluated the effects of an anesthesiologist placed preoperative transversus abdominis plane block (TAP) as part of a bariatric surgery ERAS protocol. We hypothesized that an anesthesiologist placed preoperative TAP added to an ERAS protocol following laparoscopic bariatric surgery would reduce total opioid consumption.
