Primary outcomePrimary: Patients With Pain: Numerical Rating Scale (NRS-11(0-10): 0:no Pain and 10:Severe/Worst Pain) ≥ 4 — 19; 5; 11 participants

Summary

The investigators undertook this prospective, randomized trial to compare the recovery profile throughout the first postoperative week in patients receiving continuous (CISB) interscalene brachial plexus block, single injection (SISB), or general anesthesia (GA) for arthroscopic rotator cuff repair surgery. Specifically, the effects of the three anesthetic techniques when used intraoperatively as a sole anesthesia modality were studied on postoperative pain, time-to-first pain, analgesic consumption, fast-tracked PACU bypass rate, length of PACU stay, time-to-discharge home, sleep duration, and related adverse effects. The investigators hypothesized that CISB results in a superior postoperative recovery profile as compared to SISB or GA alone.
