Background and Objectives Surgical trauma, pain and opioids can cause nausea, vomiting, ileus and increased length of hospital stay. The primary objective of the study was to evaluate the time to recovery of gastrointestinal function and the time to meet hospital discharge criteria after laparoscopic bariatric surgery with intraoperative intravenous lidocaine administration. Secondary objectives were to evaluate morphine consumption during the first 24 h and the side effects of opioids.
