Which nerve block offers better pain relief after rotator cuff repair?
NCT ID NCT03743974
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This trial compares two ultrasound-guided nerve blocks—interscalene and supraclavicular—for controlling pain after outpatient arthroscopic rotator cuff repair. About 108 adults undergoing surgery will receive one of the two blocks, and researchers will measure how much opioid pain medication they take at home during the first 48 hours. The goal is to see if the supraclavicular block works as well as the standard interscalene block.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound-guided nerve block (interscalene or supraclavicular)
- What this could lead to
- If one block proves better, it could improve pain management and reduce opioid use after shoulder surgery.
- What could go wrong
- This is a small, single-surgeon study; results may not apply to all patients or procedures. Both blocks carry risks like nerve injury or breathing problems.
