U.S., March 17 -- ClinicalTrials.gov registry received information related to the study (NCT07474896) titled 'Diaphragm-Sparing Regional Anesthesia Techniques for Shoulder Surgery' on Dec. 04, 2025.
Brief Summary: This study will compare two regional anesthesia techniques for shoulder surgery and evaluate their effects on diaphragmatic function. The standard regional anesthesia technique for shoulder surgery is the interscalene brachial plexus block (ISB), which provides effective analgesia but is frequently associated with ipsilateral hemidiaphragmatic paresis due to phrenic nerve involvement.
An alternative diaphragm-sparing strategy is the combination of a suprascapular nerve block (SSNB) and an infraclavicular brachial plexus block (I...
