Mahidol University·interventional·Posted Aug 24, 2020·Updated May 9, 2025

In Brief

A Phase 4 clinical trial evaluating Lidocaine Hydrochloride, Ketamine, and 1 other intervention for Laparoscopic Bariatric Surgery. Completed, enrolled 87 participants across 1 site.

Detailed Summary

The most effective long-term treatment for obesity is bariatric surgery, however, postoperative pain control is challenging in these group of population. Opioid-sparing technique with multimodal analgesia is recommended but the evidence supported is still limited. Multimodal analgesia, particularly lidocaine and ketamine, has been used effectively in various type of surgery. However, the evidence supported their use in obese patients undergoing bariatric surgery is limited.
