Summary

This study tests whether an ultrasound-guided nerve block, given before lumbar spine surgery, can reduce the need for strong painkillers (opioids) afterward. Fifty adults scheduled for back surgery will be randomly assigned to receive either the nerve block plus standard pain care or standard care alone. Researchers will measure total opioid use in the first 24 hours, pain levels, and recovery outcomes.

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 (injected as a nerve block)

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 opioids.

What could go wrong

This is a small, early-stage trial with only 50 participants, so results may not apply to everyone. The nerve block itself carries small risks like bleeding or infection.
