Response - NO
Brief Summary   This study compares two modern shoulder nerve blocks - Sub omohyoid anterior suprascapular (SSNB) and selective superior trunk block (STB) - to determine which provides better analgesia with fewer side effects for patients undergoing arthroscopic shoulder arthroscopic surgery. Traditional interscalene blocks though effective can cause diaphragmatic palsy and respiratory depression. Newer diaphragm sparing blocks like SSNB and STB may offer similar analgesia with improved safety but direct comparison between them is limited. This prospective observational study will include 64 participants (ASA I-II) undergoing elective unilateral shoulder arthroscopy. Patients will receive either of the blocks using 10 ml of 0.5% bupivacaine along with superficial cervical plexus block. Pain scores, total analgesic consumptions, diaphragmatic movement using USG, complications and patient satisfaction will be assessed.
