New nerve block could ease shoulder surgery pain
NCT ID NCT07666737
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a nerve block called PENG (pericapsular nerve group block) to see if it can reduce pain and the need for painkillers after shoulder surgery. Sixty adults having arthroscopic shoulder surgery will receive the block with one of two different volumes of anesthetic. The goal is to find a better way to control early postoperative pain without affecting muscle movement.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- local anesthetic (bupivacaine or similar)
- What this could lead to
- If it works, this could provide a better way to manage pain after shoulder surgery, reducing the need for opioids.
- What could go wrong
- This is a small, early-stage study with only 60 participants, so results may not apply to everyone. The nerve block may not work as expected or could cause side effects like allergic reactions.
