Comparison of ultrasound-guided supraclavicular and costoclavicular brachial plexus blocks in pediatric patients: a randomized clinical trial.

Although costoclavicular block did not show superiority in pain management, the block performance was perceived as more practical than supraclavicular block. We believe that costoclavicular brachial plexus block stands as a good option in upper extremity surgeries with the advantages of shorter block performance time and reduced ipsilateral hemidiaphragm paralysis risk in pediatric patients.
