New combo approach aims to ease pain after gallbladder surgery
NCT ID NCT07653490
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a nerve block (erector spinae plane block) combined with low-flow anesthesia can improve recovery and reduce opioid use after laparoscopic gallbladder removal. 72 adults aged 18-65 will be randomly assigned to receive either the nerve block plus low-flow anesthesia or standard care. The main goal is to see if patients feel better 24 hours after surgery, with less pain and fewer side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine
- What this could lead to
- If this works, it could offer a way to reduce pain and opioid use after gallbladder surgery, leading to a smoother recovery.
- What could go wrong
- This is a small, early-stage study with only 72 participants. The results may not apply to everyone, and the nerve block carries risks like infection or allergic reaction.
