Which nerve block wins for gallbladder pain?
NCT ID NCT07533279
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two types of nerve blocks to see which one controls pain better after open gallbladder removal. Sixty-six adults will receive either an erector spinae plane block or an external oblique intercostal plane block before surgery. Researchers will measure pain scores, opioid use, and time until first pain request. The goal is to find the more effective technique for safer, more comfortable recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- local anesthetic (nerve block)
- What this could lead to
- If one nerve block proves better, it could become the standard for pain control after gallbladder surgery, reducing opioid use and speeding recovery.
- What could go wrong
- This is a small, early-stage trial with only 66 people. Results may not apply to everyone, and nerve blocks carry small risks like infection or bleeding.
