Week-Long nerve block after amputation may stop phantom pain and slash opioid use

NCT ID NCT03461120

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a continuous nerve block given for 7 days after a leg amputation can prevent phantom limb pain and improve physical and emotional function. About 200 adults scheduled for a lower-limb amputation will receive either a high-concentration numbing medicine or a low-concentration one for one day followed by saltwater. The goal is to see if the longer, denser block reduces pain and the need for opioids.

What this could mean

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

Active substance

bupivacaine or ropivacaine (local anesthetics)

What this could lead to

If it works, this could point toward a standard way to prevent chronic phantom limb pain and reduce reliance on opioids after amputation.

What could go wrong

This is a Phase 4 trial, so the drugs are already approved, but the specific 7-day block approach may not prove better than standard care. Results may not apply to all amputation types.
