Which nerve block eases shoulder surgery pain best?
NCT ID NCT07445126
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two common nerve block techniques for shoulder surgery pain. Sixty adults having arthroscopic shoulder surgery will receive either an interscalene block alone or a combined interscalene and suprascapular block. Researchers will measure pain scores, painkiller use, and breathing side effects for 24 hours after surgery to see which method works better.
