NCT ID NCT07018258
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 120 adults having gallbladder surgery to see if the position they are in when getting a nerve block (called an ESP block) affects pain after surgery. Patients were placed on their side, stomach, or sitting up during the block. The goal was to find which position gives the best pain relief and makes patients most satisfied.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Erector Spinae Plane (ESP) block
- What this could lead to
- If successful, this could help doctors choose the best patient position for a nerve block to improve pain relief and reduce the need for extra painkillers after gallbladder surgery.
- What could go wrong
- This is a small, completed study comparing positions, not testing a new treatment. The results may not apply to other surgeries or patients with different health conditions.
