Summary

This study was designed to find the best dose of intravenous lidocaine for controlling pain after bariatric bowel surgery. Lidocaine is a local anesthetic that may reduce the need for opioids, which can cause nausea and other side effects. The trial planned to compare two doses in adults undergoing major bowel surgery, but it was withdrawn before any participants were enrolled.
