Can a simple nerve block prevent breathing trouble after obesity surgery?
NCT ID NCT07022600
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested whether a nerve block (erector spinae plane block) can reduce diaphragm dysfunction after laparoscopic sleeve gastrectomy in severely obese patients. 80 participants were randomly assigned to receive either the nerve block or a placebo. The researchers measured diaphragm movement and lung function before and after surgery. The goal is to see if this technique can prevent breathing complications common in this group.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- bupivacaine (a local anesthetic used in the nerve block)
- What this could lead to
- If it works, this could point toward a simple way to reduce breathing problems after weight-loss surgery in severely obese patients.
- What could go wrong
- This is a small, completed study with only 80 patients. The nerve block may not improve diaphragm function, and results may not apply to all patients.
