Nerve block may cut opioid use after back surgery

NCT ID NCT07695987

First seen Jul 10, 2026 · Last updated Jul 10, 2026

Summary

This study compares two ways to control pain after a single-level lumbar microdiscectomy (a common back surgery). One group receives an ultrasound-guided nerve block (quadro-iliac plane block) with bupivacaine, while the other gets standard local infiltration of pain medicine at the surgical site. Both groups also have a patient-controlled pain pump. The main goal is to see which approach reduces total opioid use in the first 24 hours after surgery, with additional measures of pain scores, side effects, and recovery quality.

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 effective, this nerve block could become a standard way to manage pain after back surgery, reducing the need for strong opioids and improving recovery.
What could go wrong
This is a small, early-stage trial (60 participants) comparing two established techniques, so the difference may be small or not statistically significant. Nerve blocks carry rare risks like infection or bleeding.
