Stellate Ganglion Nerve Block by Point-of-Care Ultrasonography for Treatment of Refractory Infarction-Induced Ventricular Fibrillation.

Stellate ganglion blockade has been previously suggested as a treatment option for intractable ventricular arrhythmia; however, its use in emergency department management of pulseless arrest with shockable rhythm has not been described. We report the case of a 65-year-old man brought in by ambulance who complained of chest pain and received an out-of-hospital ECG suggestive of anterior-wall ST-segment elevation myocardial infarction. Shortly after arrival, the patient became unresponsive, with no palpable pulse, and was found to be in ventricular fibrillation.
