Opioid Free Anesthesia and Bariatric Surgery

Opioid Free Total Intravenous Anesthesia Within an Enhanced Recovery After Surgery Pathway for Bariatric Surgery: A Randomized Controlled Clinical Trial

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.
