The interscalene block (ISB) is the gold standard but frequently causes phrenic nerve paralysis and hemi-diaphragmatic paresis, limiting its use in patients with reduced pulmonary reserve. The suprascapular (SSNB) and costoclavicular (CCB) blocks are proposed diaphragm-sparing alternatives, but data directly comparing all three are limited.\n\nThis randomised, double-blinded trial will compare the incidence of hemi-diaphragmatic paresis among ultrasound-guided ISB, SSNB, and CCB in elective shoulder surgery. Seventy-five ASA I-II patients aged 18-70 will be allocated 1:1:1 to one block. The primary outcome is the incidence of hemi-diaphragmatic paresis, measured by ultrasound diaphragmatic excursion before induction and after recovery in the PACU. Secondary outcomes include postoperative pain, analgesic consumption, and patient satisfaction. The investigators hypothesise that SSNB and CCB will cause less hemidiaphragmatic paresis than ISB while providing comparable analgesia.",[26,27,28,29],"Hemidiaphragmatic Paralysis","Postoperative Pain","Shoulder Surgery","Brachial Plexus Block",[31,32,33,34,35,36],"Interscalene block","Suprascapular nerve block","Costoclavicular block","Diaphragmatic excursion","Ultrasound-guided regional anesthesia","Phrenic nerve palsy","NOT_YET_RECRUITING","2026-06-22",{"date":40,"type":41},"2026-06-26","ACTUAL",{"date":43,"type":20},"2026-06-25",{"date":45,"type":20},"2027-01-01",{"name":47,"class":48},"Menoufia University","OTHER",{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":4,"eligibilityCriteria":55,"healthyVolunteers":11,"sex":15,"minAge":16,"maxAge":56,"enrollmentInfo":57,"targetDuration":4,"studyType":59,"phases":4,"briefSummary":60,"conditions":61,"keywords":67,"overallStatus":74,"whyStopped":4,"lastUpdateSubmitDate":75,"lastUpdatePostDateStruct":76,"startDateStruct":78,"completionDateStruct":80,"leadSponsor":82,"locationsCount":85},"100635509","the-effects-of-regional-anaesthesia-techniques-on-hemidiaphragm-paralysis-postoperative-recovery-quality-opioid-consumption-and-pain-scores-100635509","NCT07553611","The Effects of Regional Anaesthesia Techniques on Hemidiaphragm Paralysis, Postoperative Recovery Quality, Opioid Consumption, and Pain Scores","Comparion of the Effects of Ultrasound-guided Interscalene Block, Erector Spinae Plane Block, Costoclavicular Block, and Supraclavicular Block on Hemidiaphragm Paralysis, Postoperative Recovery Quality, Opioid Consumption, and Pain Scores in Patients Undergoing Arthroscopic Shoulder Surgery: a Prospective Observational Trial","Inclusion Criteria:\n\n* aged 18-65 years\n* American Society of Anaesthesiology (ASA) score I-III\n* body mass index (BMI) \\\u003C30kg\u002Fm2\n* scheduled for elective arthroscopic surgery\n\nExclusion Criteria:\n\n* ASA score ≥4\n* BMI ≥30 kg\u002Fm2\n* declining to give written informed consent\n* controendications for block application\n* history of mental or neurological disease, severe liver and\u002For kidney disease\n* history of moderate or severe pulmonary disease\n* abnormal preoperative chest X-ray findings\n* scheduled for emergency surgery","65 Years",{"count":58,"type":20},88,"OBSERVATIONAL","This study aims to evaluate the effects of ultrasound-guided interscalene, erector spinae plane, costoclavicular, and supraclavicular blocks on hemidiaphragmatic paralysis, postoperative recovery quality, opioid consumption, and pain scores.",[62,63,26,64,65,66],"Regional Anaesthesia","Arthroscopic Shoulder Surgery","Recovery Quality","Opioid Consumption","Postoperative Pain Score",[68,69,70,71,72,73],"regional anaesthesia","arthroscopic shoulder surgery","hemidiaphragmatic paralysis","recovery quality","opioid consumption","postoperative pain score","RECRUITING","2026-05-06",{"date":77,"type":41},"2026-05-11",{"date":79,"type":41},"2026-04-21",{"date":81,"type":20},"2026-11-21",{"name":83,"class":84},"Antalya Training and Research Hospital","OTHER_GOV",1,{"id":87,"slug":88,"hasResults":11,"nctId":89,"briefTitle":90,"officialTitle":91,"acronym":4,"eligibilityCriteria":92,"healthyVolunteers":11,"sex":15,"minAge":16,"maxAge":93,"enrollmentInfo":94,"targetDuration":4,"studyType":21,"phases":96,"briefSummary":98,"conditions":99,"keywords":100,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":103,"lastUpdatePostDateStruct":104,"startDateStruct":106,"completionDateStruct":108,"leadSponsor":110,"locationsCount":4},"100630336","shoulder-pericapsular-block-versus-interscalene-block-in-arthroscopic-shoulder-surgery-100630336","NCT07486349","Shoulder Pericapsular Block Versus Interscalene Block in Arthroscopic Shoulder Surgery","Ultrasound-Guided Interscalene Block Versus Shoulder Pericapsular Nerve Group (PENG) Block for Hemidiaphragmatic Paralysis in Elective Shoulder Surgery: A Randomized Controlled Trial","Inclusion Criteria:\n\n* ASA physical status I-III\n* Scheduled for elective shoulder surgery under general anesthesia\n* Able to provide informed consent\n\nExclusion Criteria:\n\n* Pre-existing diaphragmatic dysfunction\n* Severe COPD or restrictive pulmonary disease\n* Neuromuscular disorders\n* BMI \\> 40 kg\u002Fm²\n* Coagulopathy\n* Infection at injection site\n* Allergy to local anesthetics\n* Inability to undergo diaphragmatic ultrasound assessment","75 Years",{"count":95,"type":20},70,[97],"NA","This randomized controlled trial aims to compare the incidence of hemidiaphragmatic paralysis (HDP) following ultrasound-guided interscalene block (ISB) versus shoulder pericapsular nerve group (PENG) block in patients undergoing elective shoulder surgery under general anesthesia.\n\nThe primary objective is to determine whether the shoulder PENG block reduces the incidence of HDP compared with conventional intrafascial ISB.
