Ultrasound-guided Stellate Ganglion Block, an Alternative for the Management of Refractory Electrical Storm in the Emergency Department: Case Report

Bloqueo de ganglio estrellado guiado por ultrasonido, una alternativa para el manejo de la tormenta eléctrica refractaria en el servicio de emergencia: Reporte de Caso

Abstract

Electrical storm is defined as three or more episodes of sustained ventricular arrhythmias, including ventricular tachycardia or ventricular fibrillation, within a 24-hour period. Incessant ventricular fibrillation is a life-threatening condition and is associated with high morbidity and mortality. Patients often respond to traditional antiarrhythmic therapy. However, some patients are refractory to pharmacotherapy, posing significant challenges for effective management. While stellate ganglion blockade has proven effective in the treatment of patients with electrical storm, it remains underutilized. In this case report, we successfully reversed the drug-resistant arrhythmia to sinus rhythm after ultrasound-guided stellate ganglion blockade. Early application of the blockade can provide effective treatment for drug-resistant ventricular arrhythmias and prevent morbidity and mortality.
