Precision injection may improve pain relief after shoulder surgery
NCT ID NCT07695025
First seen Jul 10, 2026 · Last updated Jul 10, 2026
Summary
This study compares two different injection sites for a nerve block used to control pain after shoulder arthroscopy. The goal is to see which site provides better pain relief and reduces complications like diaphragm paralysis. Fifty adults scheduled for shoulder surgery will receive the block before general anesthesia, and their pain levels, medication use, and side effects will be tracked.

- Active substance
- Ultrasound-Guided Interscalene Block
- What this could lead to
- If one injection site proves better, it could lead to more effective pain relief and fewer side effects like diaphragm paralysis after shoulder surgery.
- What could go wrong
- This is a small, early-stage study with only 50 participants, so results may not apply to everyone. Risks include nerve damage, bleeding, or breathing issues.
