Study Summary
This clinical trial is for subjects undergoing right upper extremity surgery. The aim of the study is to investigate the dose-response relationship between local anesthetic volume and ipsilateral hemidiaphragmatic paresis (HDP) in patients getting ultrasound-guided supraclavicular brachial plexus blocks in a blinded, prospective trial.
Primary Outcome
Diaphragm motion was recorded during voluntary sniffing fifteen minutes after supraclavicular block with the specified volume of local anesthetic. Blinded investigators reviewed the scans and determined whether the scans were indicative of hemidiaphragmatic paresis (HDP) or not (No HDP). This data was fit to a dose response curve.
