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":55,"eligibilityCriteria":56,"healthyVolunteers":11,"sex":15,"minAge":16,"maxAge":17,"enrollmentInfo":57,"targetDuration":4,"studyType":21,"phases":59,"briefSummary":61,"conditions":62,"keywords":4,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":66,"lastUpdatePostDateStruct":67,"startDateStruct":69,"completionDateStruct":71,"leadSponsor":73,"locationsCount":4},"100643126","comparison-of-90-and-120-arm-positions-in-costoclavicular-block-100643126","NCT07586670","Comparison of 90° and 120° Arm Positions in Costoclavicular Block","Effect of Arm Abduction Degree ( 90° vs. 120° ) on Block Onset Time and Block Success in Costoclavicular Brachial Plexus Block in Patients Undergoing Hand, Wrist and Forearm Surgery: A Prospective Randomized Controlled Trial","COSTO-RCT","Inclusion Criteria:\n\n* Patients aged between 18 and 80 years.\n* Patients scheduled for elective upper extremity surgery (hand, wrist, forearm).\n* Patients classified as ASA I-III.\n* Patients who provide informed consent after being informed about the study.\n\nExclusion Criteria:\n\n* History of previous surgery, scar tissue, tumor, or trauma that may alter brachial plexus anatomy.\n* Presence of infection, hematoma, severe edema, burn, or open wound at the block application site.\n* Known allergy to local anesthetics or other medications used in the study.\n* Coagulopathy, use of anticoagulants, or platelet count \\\u003C 100,000\u002Fmm³.\n* History of peripheral neuropathy, neurological deficit, cervical radiculopathy, or CRPS.\n* Pregnancy or breastfeeding.\n* Patients with BMI \\\u003C 18 kg\u002Fm².\n* Patients with BMI \\> 35 kg\u002Fm².\n* Severe cardiac, pulmonary, renal, or hepatic failure.\n* Mental retardation, communication difficulties, or lack of cooperation.\n* Deformity, amputation, or large mass in the surgical extremity that may interfere with sensorimotor assessment.\n* Preoperative significant sensory loss, motor weakness, or signs of neurological disease.\n* Severe anemia (Hb \\\u003C 9 g\u002FdL) or polycythemia (Hb \\> 18 g\u002FdL).\n* Psychiatric disorders, substance abuse, or any condition that may interfere with study compliance.",{"count":58,"type":20},106,[60],"NA","The costoclavicular approach of the infraclavicular brachial plexus block is widely used for upper extremity surgeries due to its reliable anatomy and high success rates. Patient positioning, particularly the degree of arm abduction, may influence the spread of local anesthetic and the characteristics of the block. However, the optimal arm abduction angle during this procedure remains unclear.\n\nThis prospective randomized controlled trial aims to investigate the effect of two different arm abduction angles (90° and 120°) on block onset time and block success in patients undergoing hand, wrist, and forearm surgery under ultrasound-guided costoclavicular brachial plexus block.\n\nPatients will be randomly assigned to one of two groups according to the degree of arm abduction. The primary outcome is block onset time. Secondary outcomes include block success, sensory and motor block characteristics, perfusion index changes, hemodynamic parameters, readiness for surgery at 15 and 20 minutes, block performance time, need for additional anesthesia, postoperative neurological evaluation at 4 and 24 hours, complications, and patient satisfaction.\n\nThe findings of this study are expected to provide evidence on optimal patient positioning to improve the effectiveness and reliability of ultrasound-guided costoclavicular brachial plexus block.",[63,64,29,65],"Perfusion Index","Upper Extremity Surgery","Regional Anaesthesia","2026-06-06",{"date":68,"type":41},"2026-06-09",{"date":70,"type":20},"2026-05-15",{"date":72,"type":20},"2026-08-27",{"name":74,"class":75},"Ankara Etlik City Hospital","OTHER_GOV"]
