Reduction of Anterior Shoulder Dislocation under Local Anesthesia Reducing a dislocated shoulder after an Interscalene Nerve Block. Keep an eye on the shoulder or you’ll miss it. This is why I haven’t had to do a conscious sedation for shoulder dislocation in years. 15 ml of Lidocaine, no narcotics, no sedatives. - Sam Ghali, M.D. @EM_RESUS #Reduction #Anterior #Shoulder #Dislocation #clinical #video #physicalexam #procedure #msk
