New nerve block may reduce breathing side effects after shoulder surgery
NCT ID NCT07253740
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two different nerve blocks to manage pain after shoulder surgery. 60 adults were randomly assigned to receive either an interscalene block or an infraspinatus-teres minor block. The goal was to see which block reduces the need for strong painkillers and causes fewer breathing problems.
