Anesthesiologists routinely perform brachial plexus nerve blocks for shoulder surgery with the aid of nerve stimulators or ultrasonographic guidance. [30, 31] The literature suggests that an ultrasound-guided interscalene nerve block of the brachial plexus can be used to provide adequate anesthesia for the reduction of shoulder dislocations. [32, 33]

A prospective, randomized study by Blaivas et al demonstrated that an ultrasound-guided interscalene block not only is feasible in the ED but also can yield a significantly shorter ED stay than procedural sedation. [33]
