The morbidly obese bariatric surgery population is susceptible to opioid-induced complications such as respiratory depression and postoperative nausea and vomiting. This population may in particular benefit from opioid-sparing or opioid-free anesthetic techniques. This study aims to evaluate the effect of opioid free total intravenous anesthesia on postoperative quality of recovery in patients undergoing bariatric surgery.
