![]() ![]() More robust research is required to eliminate profound limitations and consider contributing factors to DSD. 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. Double sequential external defibrillation (DSED rapid sequential shocks from two defibrillators) and vector-change (VC) defibrillation (switching defibrillation pads to an anterior-posterior position) have been proposed as defibrillation strategies to improve outcomes in patients with refractory ventricular fibrillation. Use of double sequential external defibrillation for refractory ventricular fibrillation during out-of-hospital cardiac arrest. Cortez E, Krebs W, Davis J, Keseg DP, Panchal AR. Double sequential external defibrillation (DSED, also referred to as dual sequential external defibrillation) involves the provision of rapid sequential shocks via two defibrillators with defibrillation pads placed in both planes (anterior-lateral and anteriorposterior, Fig. DSD is offered as a potentially feasible RVF treatment strategy throughout. Double sequential external defibrillation for refractory ventricular fibrillation: The DOSE VF pilot randomized controlled trial. Further research is required to critically evaluate the safety and efficacy of double sequential defibrillation and the possible recommendation to be included as a part of the advanced cardiac life support protocol. ![]() 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. Double sequential defibrillation successfully terminated refractory ventricular fibrillation in our patient. ![]()
