Summary

This study tests whether a temporary catheter placed during laparoscopic sleeve gastrectomy can be used to re-dose nerve-blocking medicine (bupivacaine and dexamethasone) if severe pain or nausea break through after surgery. It includes 30 high-risk patients, such as young women or those with a history of severe post-surgery symptoms. The goal is to see if this approach is safe, feasible, and effective at reducing pain and nausea without needing extra opioids.

What this could mean

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

Active substance
bupivacaine and dexamethasone
What this could lead to
If it works, this approach could offer a way to manage severe pain and nausea after gastric sleeve surgery without relying on opioids.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The catheter placement itself carries risks like infection or blockage.
