Regional anesthetics are often the preferred route for patients who are having orthopedic shoulder procedures (Rai & Bhutia, 2017). Traditionally, plain local anesthetics, like bupivacaine or ropivacaine, are used as the local anesthetic of choice because of their fast onset and relatively predictable duration of action. However, several different additives have been trialed to prolong the duration or improve the density of regional blocks. When looking at additives to regional anesthetic techniques, side effects and duration of the block can be unpredictable and unpleasant. For example, additives like fentanyl, morphine, and dexamethasone have been trialed in regional techniques and have been shown to produce itching, nausea and vomiting, respiratory depression, and hemodynamic instability (Rai & Bhutia, 2017). Will adding dexmedetomidine to upper extremity regional anesthetic techniques produce adequate anesthesia while reducing the incidence of side effects and the need for opioids in the postoperative period?
