Nerve block showdown: which technique cuts hernia surgery pain best?
NCT ID NCT07676123
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This trial compares two types of nerve blocks—Quadratus Lumborum and Ilioinguinal-Iliohypogastric—given before laparoscopic inguinal hernia repair. The goal is to see which block reduces the need for opioid painkillers during surgery and lowers the risk of long-term pain afterward. Adults having their first hernia repair and without chronic pain are eligible.
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 one block proves better, it could become the standard for reducing pain and opioid use after hernia surgery.
- What could go wrong
- This is a small, early-stage comparison. Results may not apply to all patients, and individual responses to nerve blocks vary.
