New nerve block technique aims to numb hand surgery with less anesthetic
NCT ID NCT07326943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing the smallest amount of the anesthetic ropivacaine needed to numb the arm for hand and forearm surgery using a targeted nerve block. Researchers will inject decreasing doses around the C7 nerve root in the neck and check how well it blocks sensation and movement. The goal is to find a dose that works reliably while using as little medication as possible.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ropivacaine 0.5%
What this could lead to
If successful, this could establish a reliable nerve block technique for hand and forearm surgery using the lowest effective dose of anesthetic.
What could go wrong
This is a small, early-phase dose-finding study with only 56 participants. Results may not apply to all patients or surgeries, and there is a risk of incomplete block or side effects like diaphragm weakness.
