Double Sequential External Defibrillation: A New Frontier in the Treatment of Refractory Ventricular Fibrillation?

Refractory ventricular fibrillation (VF) remains one of the most formidable challenges in cardiopulmonary resuscitation. Despite significant advances in the management of out-of-hospital cardiac arrests, some patients do not respond to standard defibrillation techniques, seriously compromising their chances of survival. In this context, new defibrillation approaches have emerged in recent years, particularly double sequential external defibrillation […]

Double Sequential External Defibrillation and Vector Change Defibrillation for Refractory Ventricular Fibrillation

Study Objective The objective of this study (DOSE VF) was to evaluate the effectiveness of double sequential external defibrillation (DSED) and vector change (VC) defibrillation compared to standard defibrillation in patients with refractory ventricular fibrillation during out-of-hospital cardiac arrest.   Methodology   Study Design: – 3-group cluster-randomized controlled trial with crossover – Conducted in 6 […]
