Defibrillation Strategies for Refractory Ventricular Fibrillation. Cheskes S, Verbeek PR, Drennan IR, et al. RCUK will make any necessary changes to its guidelines following the forthcoming ILCOR update.ฤก. Prompt treatment with resuscitation and defibrillation can be lifesaving. The most common cause of VF is ischemic cardiomyopathy, especially in the context of an acute coronary event. RCUK guidelines are based on the ILCOR evidence review, and would consider the additional resources, training and equipment safety issues required to implement DSED. Ventricular fibrillation (VF) is a life-threatening cardiac arrhythmia that can lead to loss of cardiac function and sudden cardiac death. Lastly no damage or defibrillation malfunction was reported throughout this study and the authors justified using a sequential-only approach to DED due to a prior case report which reported damage to their defibrillators following dual defibrillation. The International Liaison Committee on Resuscitation (ILCOR) is currently reviewing this new evidence to update its Consensus on Science and Treatment Recommendations. 1 Vector change defibrillation is already a part of RCUK ALS guidelines for refractory ventricular fibrillation. In their randomised controlled trial, Cheskes and colleagues report that among patients with refractory ventricular fibrillation (defined as failure to terminate VF after three antero-lateral shocks), survival to hospital discharge was more frequent in those who received double sequential external defibrillation (DSED) or vector change defibrillation (antero-posterior) compared to those receiving standard defibrillation. Double (dual) sequential defibrillation for refractory ventricular fibrillation cardiac arrest: A systematic review. Resuscitation Council UK welcomes new research findings about defibrillation strategies for refractory ventricular fibrillation. The authors of this review utilize the term dual sequential defibrillation (DSD). Double Sequential External Defibrillation: Pads are placed in both the anterior-anterior and the anterior-posterior pad placements following the third shock with standard defibrillation.
