New nerve block could slash opioid use after back surgery
NCT ID NCT07334288
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether an ultrasound-guided nerve block, given before lumbar spine surgery, can reduce pain and the need for opioid painkillers afterward. Fifty adults scheduled for back surgery will be randomly assigned to receive either the nerve block plus standard pain management or standard care alone. Researchers will measure total opioid use in the first 24 hours, pain levels, and side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Bupivacaine and Epinephrine (nerve block injection)
- What this could lead to
- If it works, this could offer a better way to manage pain after back surgery, reducing the need for strong painkillers like opioids.
- What could go wrong
- This is a small, early-stage trial with only 50 participants. The nerve block may not provide significant extra pain relief, and there are rare risks like allergic reaction or nerve damage from the injection.
