A Prospective, Randomized Comparison between Ultrasound and Nerve Stimulation Guidance for Multiple Injection Axillary Brachial Plexus Block

Abstract
AXILLARY brachial plexus anesthesia is widely used for upper extremity surgery. Nerve stimulation has become the gold standard technique for nerve location, and the multiple injection technique with nerve stimulation has been demonstrated to provide more effective anesthesia than either double or single injection for axillary brachial plexus block.1
