Anterior suprascapular and axillary nerve blocks plus diaphragm-friendly approach for shoulder surgery
Official title: Comparison of Anterior Suprascapular and Axillary Nerve Block Versus Interscalene Block for Postoperative Analgesia and Diaphragmatic Function in Shoulder Surgery: A Randomized Controlled Trial
Run by Ankara Etlik City Hospital · NCT07739303 · Data updated 2026-11-12
This study tests whether a diaphragm-sparing anterior suprascapular plus axillary nerve block provides pain relief for shoulder surgery as well as or better than the standard interscalene block.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–65 undergoing elective shoulder arthroscopy without significant pulmonary disease, coagulopathy, local anesthetic allergies, or chronic opioid use.
✕Probably not a fit
Those with contraindications to regional anesthesia or who do not respond to nerve blocks may not receive the intended analgesic benefit.

What this trial studies
Shoulder arthroscopy often causes significant postoperative pain, and traditional interscalene blocks can affect diaphragmatic function. This trial compares an ultrasound-guided anterior suprascapular block combined with the axillary nerve block to the interscalene block in adults undergoing elective shoulder surgery. Primary aims include analgesic effectiveness and preservation of diaphragmatic function. The study is conducted at Ankara Etlik City Hospital and uses standard regional anesthesia techniques. Eligible participants are adults 18–65 without major respiratory disease or coagulopathy, and without prior chronic opioid use.
Why it matters
Potential benefit: If successful, patients may experience similar or better pain control with fewer breathing side effects than interscalene blocks.
How similar studies have gone: Previous work suggests that diaphragm-sparing nerve blocks can provide effective analgesia with reduced diaphragmatic impairment, though direct comparisons to interscalene blocks are still being explored.
