New study aims to find best pain relief for kids after surgery
NCT ID NCT07426939
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will compare two types of nerve blocks—erector spinae plane block and caudal block—in 78 children aged 1 to 8 years undergoing lower abdominal surgery. The goal is to see which method provides better pain control after surgery, using a standard pain scale. Both blocks are given with ultrasound guidance to improve safety and accuracy.
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 (bupivacaine or similar)
- What this could lead to
- If one method proves better, it could offer children more effective pain relief with fewer side effects after surgery.
- What could go wrong
- This is a small, early-stage comparison study, so results may not apply to all children or surgeries. Both blocks carry rare risks like infection or bleeding.
