About this study

Ultrasound guided supraclavicular brachial plexus block (BPB) has been extensively studied and recommended as a sole anesthetic for upper extremity surgeries. The efficacy of ultrasound-guided (USG) SeTB for surgical anesthesia of the entire upper extremity and cadaver anatomic study evaluating the spread of the injectate after a simulated SeTB is further confirmed from the results of our previous research. Although the results in our previous study are encouraging, there is a paucity of data on sensorimotor blockade and incidence of hemidiaphragmatic palsy after a SeTB, and no data comparing SeTB with a supraclavicular BPB techniques which this study aims to evaluate. We hypothesise that USG SeTB is superior to supraclavicular BPB in anesthetising the entire upper extremity from the shoulder to hand.
