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.",[28,29],"Postoperative Pain","Shoulder Arthroscopy",[31,32,33,34],"Interscalene Brachial Plexus Block","Serratus Posterior Superior Intercostal Plane Block","Regional Anesthesia","Ultrasound-Guided Nerve Block","RECRUITING","2026-06-25",{"date":38,"type":39},"2026-06-29","ACTUAL",{"date":36,"type":39},{"date":42,"type":22},"2026-12-15",{"name":44,"class":45},"Ferit Yetik","OTHER_GOV",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":53,"eligibilityCriteria":54,"healthyVolunteers":11,"sex":55,"minAge":18,"maxAge":19,"enrollmentInfo":56,"targetDuration":4,"studyType":23,"phases":57,"briefSummary":58,"conditions":59,"keywords":61,"overallStatus":35,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":68,"leadSponsor":70,"locationsCount":46},"100642239","riss-versus-spsip-block-in-modified-radical-mastectomy-100642239","NCT07659990","RISS Versus SPSIP Block in Modified Radical Mastectomy","Comparison of Rhomboid Intercostal-Subserratus Plane Block and Serratus Posterior Superior Intercostal Plane Block for Postoperative Analgesia and Dermatomal Spread After Modified Radical Mastectomy: A Randomized Double-Blind Trial","RSMRM","Inclusion Criteria:\n\n* Female patients aged 18-75 years\n* ASA physical status I-III\n* Scheduled for elective unilateral modified radical mastectomy with axillary dissection under general anesthesia\n* Provision of written informed consent\n\nExclusion Criteria:\n\n* Anticoagulant therapy\n* Bleeding diathesis\n* Known allergy to local anesthetics or opioids\n* Infection at the block application site or previous surgery in the block area\n* Cognitive impairment preventing NRS assessment\n* Pregnancy or lactation\n* Chronic opioid use\n* Severe hepatic or renal failure\n* Refusal to participate in the study\n* Technical inability to perform the block or failed block","FEMALE",{"count":21,"type":22},[25],"This prospective randomized double-blind controlled trial aims to compare the postoperative analgesic efficacy and dermatomal spread of rhomboid intercostal-subserratus plane (RISS) block and serratus posterior superior intercostal plane (SPSIP) block in patients undergoing modified radical mastectomy.
