Refractory Ventricular Fibrillation We conducted a cluster randomized trial with crossover among six canadian paramedic services to evaluate dsed and vc defibrillation as compared with standard defibrillation in adult patients with. The dose vf trial was conducted in the pre hospital setting, but we recommend clinicians consider either dsed or vc defibrillation for refractory vf after three failed standard shocks regardless of the location.
Dose Vf Rebel Em Emergency Medicine Blog The dose vf (defibrillation strategies for refractory ventricular fibrillation) trial enrolled patients with out‐of‐hospital cardiac arrest with refractory vf to compare dsed versus vector change defibrillation versus standard defibrillation. In our study, we applied inclusion criteria similar to those of dose vf and found that 95% of the cases who would have been perceived to have refractory vf actually had recurrent vf. the majority of patients (56%) even had successful termination of vf by all three standard shocks. The dose vf trial used a pragmatic definition of refractory vf: patients remaining in vf after three successive shocks, each separated by two minutes of cpr. paramedics did not assess rhythm changes during cpr to determine if vf was terminated and then recurred. The original publication of the dose vf trial showed that alternative defibrillation strategies of dsed and vector change (anterior posterior pad placement) defibrillation demonstrated a survival benefit for patients compared to standard defibrillation for recurrent vf.

The original publication of the dose vf trial showed that alternative defibrillation strategies of dsed and vector change (anterior posterior pad placement) defibrillation demonstrated a survival benefit for patients compared to standard defibrillation for recurrent vf. Two alternative strategies, double sequential external defibrillation (dsed) and vector change (vc) defibrillation, aim to enhance defibrillation success where conventional methods fail. this review evaluates the clinical feasibility, safety, and implementation barriers of dsed and vc in rvf cases. Double sequential external defibrillation (dsed) and vector change defibrillation have been proposed as viable options for patients in refractory ventricular fibrillation (vf) during out of hospital cardiac arrest. This secondary analysis of the dose vf trial provides more nuance on the effectiveness of double sequential external defibrillation (dsed) over standard and vector change (vc) defibrillation for patients with refractory ventricular fibrillation (rvf). We conducted a cluster randomized trial with crossover among six canadian para medic services to evaluate dsed and vc defibrillation as compared with standard defibrillation in adult patients with refractory ventricular fibrillation during out of hospital cardiac arrest.
