rehabilitation. Interscalene brachial plexus block (ISB) is widely used for postoperative analgesia in shoulder surgery; however, it may be associated with complications such as phrenic nerve paralysis. The serratus posterior superior intercostal plane (SPSIP) block is a recently described fascial plane block that may provide effective analgesia while avoiding some of the limitations of ISB.\n\nThis prospective, randomized, double-blind controlled trial aims to compare the analgesic efficacy of ISB and SPSIP block in patients undergoing elective arthroscopic shoulder surgery under general anesthesia. The primary outcome is total postoperative opioid consumption during the first 24 hours after surgery. Secondary outcomes include postoperative pain scores, quality of recovery, time to first rescue analgesia, rescue analgesic requirements, intraoperative opioid consumption, sensory block distribution, motor block characteristics, and block-related complications.",[98,99],"Postoperative Pain","Shoulder Arthroscopy",[23,28,101,102],"Regional Anesthesia","Ultrasound-Guided Nerve Block","2026-06-25",{"date":105,"type":106},"2026-06-29","ACTUAL",{"date":103,"type":106},{"date":109,"type":92},"2026-12-15",{"name":73,"class":6},1]
