Dual sequential defibrillation1/22/2024 Defibrillation Strategies for Refractory Ventricular Fibrillation. Dual sequential defibrillation (DSD) is the use of 2 defibrillators to simultaneously, or nearly simultaneously, deliver maximum energy doses via 2 separate pairs. Alternatives to the traditional approach to defibrillation have also recently been explored for the treatment of rVF. Cardiac defibrillation is the act of administering a transthoracic electrical current to a person experiencing one of the two lethal ventricular dysrhythmias, ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Cheskes S, Verbeek PR, Drennan IR, et al. Dual sequential defibrillation and vector change defibrillation. In the latter case a second pair of electrodes in addition to the traditional pair is placed in. RCUK will make any necessary changes to its guidelines following the forthcoming ILCOR update.ฤก. dual defibrillation (dual-sequential defibrillation DSD). Cheskes S, Wudwud A, Turner L, McLeod S, Summers J, Morrison LJ, et al. RCUK guidelines are based on the ILCOR evidence review, and would consider the additional resources, training and equipment safety issues required to implement DSED. Double (dual) sequential defibrillation for refractory ventricular fibrillation cardiac arrest: a systematic review. 2528 Survival decreases as the number of defibrillation attempts required increases. At least 20 of patients with ventricular fibrillation (VF)/pulseless ventricular tachycardia (pVT) will remain in a shockable rhythm after 3 shocks. The International Liaison Committee on Resuscitation (ILCOR) is currently reviewing this new evidence to update its Consensus on Science and Treatment Recommendations. This is a new topic in response to the increasing use of double (dual) sequential defibrillation (DSD). 1 Vector change defibrillation is already a part of RCUK ALS guidelines for refractory ventricular fibrillation. Objectives: The primary objective was to determine the feasibility and safety of a cluster randomized controlled trial (RCT) with crossover comparing vector change defibrillation (VC) or double sequential external defibrillation (DSED) to standard defibrillation for patients experiencing refractory ventricular fibrillation (VF). 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. IntroductionDouble sequential external defibrillation (DSED) in cardiopulmonary resuscitation has shown different results in comparison with standard defibrillation in the treatment of refractory ventricular fibrillation (RVF). Resuscitation Council UK welcomes new research findings about defibrillation strategies for refractory ventricular fibrillation.
