A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of ultrasound-guided Selective Trunk Block (SeTB) compared to the traditional Supraclavicular Brachial Plexus Block (BPB) for anesthesia during upper extremity surgeries. The research aims to determine if SeTB provides superior sensorimotor blockade and reduces the incidence of hemidiaphragmatic palsy. By analyzing the spread of anesthetic agents and their effects on major nerves, the study seeks to improve surgical outcomes and patient safety. Participants will be ASA 1-3 patients undergoing elective or emergency surgeries involving the upper extremity.
