Nerve block showdown: which technique spares kids from opioids after surgery?

NCT ID NCT07711496

First seen Jul 17, 2026 · Last updated Jul 17, 2026

Summary

This trial compares two ultrasound-guided nerve blocks—anterior quadratus lumborum block and retrolaminar block—for pain relief in children aged 6 months to 12 years undergoing lower urogenital surgery. Both blocks use the numbing medicine bupivacaine. The study measures how much extra pain medicine is needed in the first 24 hours after surgery, along with pain scores and side effects. The goal is to find which block provides better pain control and reduces opioid use.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
two ultrasound-guided nerve blocks: anterior quadratus lumborum block and retrolaminar block, both using bupivacaine
What this could lead to
If one block proves better, it could become the standard for pain control in children after lower urogenital surgery, reducing opioid needs and speeding recovery.
What could go wrong
This is a small, single-center trial, so results may not apply to all hospitals or surgeries. Both blocks are already used, so the difference may be small or not clinically meaningful.
