Interscalene Block vs SPSIP Block for Shoulder Arthroscopy analgesia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind trial compares two ultrasound-guided nerve blocks—Interscalene Brachial Plexus Block (ISB) and Serratus Posterior Superior Intercostal Plane (SPSIP) block—for adults undergoing elective shoulder arthroscopy under general anesthesia. The primary endpoint is total opioid use in the first 24 hours after surgery; secondary endpoints include pain scores, recovery quality, and analgesic timing and use. All participants receive standardized anesthesia and multimodal postoperative pain relief. Eligible adults 18–75 without major exclusions will be randomized to receive one of the blocks with appropriate blinding and outcome assessment.
