Preperitoneal Bupivacaine Infiltration Reduces Postoperative Opioid Consumption, Acute Pain, and Chronic Postsurgical Pain After Bariatric Surgery: a Randomized Controlled Trial

Introduction A multimodal pain treatment including local anesthetics is advised for perioperative analgesia in bariatric surgery. Due to obesity, bariatric surgery patients are at risk of respiratory complications. Opioid consumption is an important risk factor for hypoventilation. Furthermore, acute postoperative pain is an important risk factor for chronic postsurgical pain. In this study, we aimed to evaluate whether preperitoneal anesthesia with bupivacaine would reduce pain and opioid consumption after bariatric surgery.
