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 The trial planned to compare two doses in adults undergoing major bowel surgery, but it was withdrawn before any participants were enrolled.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
lidocaine
What this could lead to
If successful, this could point toward a standard lidocaine dosing schedule to improve pain relief and reduce opioid use after bariatric surgery.
What could go wrong
This trial was withdrawn before enrolling any participants, so no data exists. The findings may not apply to other surgeries or patient groups.
