Use of double sequential external defibrillation for refractory ventricular fibrillation during out-of-hospital cardiac arrest. Double defibrillation, harnessing two defibrillators to administer simultaneous or double sequential shocks (sometimes called the one-two punch), has seen increased use among various EMS.

More robust research is required to eliminate profound limitations and consider contributing factors to DSD. Double sequential external defibrillation for refractory ventricular fibrillation: The DOSE VF pilot randomized controlled trial. However, results are consistently limited by varying protocol and small study groups and DSD success is likely multifactorial.Conclusion:The current systematic literature review indicated that no confirmed association existed between DSD and improved OHCA outcomes. DSD is offered as a potentially feasible RVF treatment strategy throughout. The purpose of this discussion and case report is to highlight the use of double sequence defibrillation (DSD) for refractory ventricular fibrillation (RVF). To avoid possible defibrillator damage, double sequential and not simultaneous defibrillation was performed. double sequential in adult out-of-hospital cardiac arrestīackground:Refractory ventricular fibrillation (RVF) in out-of-hospital cardiac arrest (OHCA) poses a significant challenge to paramedic teams and is further confounded by an absence of specific guidance on the management of this patient category.Objective:To conduct a systematic literature review to determine whether double sequential defibrillation (DSD) improves patient outcomes in adult OHCA.Methods:Electronic searches of CINAHL, MEDLINE and AMED databases were carried out, using EBSCOhost (2017) and a subsequent filtering process.Results:Three case series and two cohort studies provided the highest category of evidence to evaluate.
