Randomized Controlled Trial Multicenter Study
DOuble Sequential External Defibrillation for Refractory Ventricular Fibrillation: The DOSE VF Pilot Randomized Controlled Trial.
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). Secondary objectives were to assess the rates of VF termination (VFT) and return of spontaneous circulation (ROSC). ⋯ Our findings suggest the DOSE-VF protocol is feasible and safe. Rates of VFT and ROSC were higher in the VC and DSED than standard defibrillation. The results of this pilot trial will allow us to inform a multicenter cluster RCT with crossover to determine if alternate defibrillation strategies for refractory VF may impact clinical outcomes.

Prognostic value of somatosensory evoked potential in cardiac arrest patients without withdrawal of life-sustaining therapy.
The reliability of somatosensory evoked potential (SSEP) to predict a poor outcome of cardiac arrest patients after targeted temperature management (TTM) has been questioned due to self-fulfilling prophecy. ⋯ Our results provide further evidence that SSEP exactly predicts poor neurological outcome in these patients and suggest that caution be taken when the brainstem reflex is used as a single test to make decisions regarding WLST.

The TTM2-trial is a multi-centre randomised clinical trial where targeted temperature management (TTM) at 33 °C will be compared with normothermia and early treatment of fever (≥37.8 °C) after Out-of-Hospital Cardiac Arrest (OHCA). This paper presents the design and rationale of the TTM2-trial follow-up, where information on secondary and exploratory outcomes will be collected. We also present the explorative outcome analyses which will focus on neurocognitive function and societal participation in OHCA-survivors. ⋯ The TTM2-trial follow-up is a pragmatic yet detailed pre-planned and standardised assessment of patient's outcome designed to ensure data-quality, decrease missing data and provide optimal conditions to investigate clinically relevant effects of TTM, including OHCA-survivors' neurocognitive function and societal participation.

Modified volumetric capnography-derived parameter: A potentially stable indicator in monitoring cardiopulmonary resuscitation efficacy in a porcine model.
We aimed to investigate whether the ability of the volumetric capnography-derived parameter, the volume of CO2 eliminated per minute and per kg body weight (V'CO2 kg-1), in monitoring the quality of CPR and predicting the return of spontaneous circulation (ROSC) remains undisturbed by hyperventilation. ⋯ V'CO2 kg-1 performs better than PETCO2 in monitoring the quality of CPR during hyperventilation. In predicting ROSC during variations in a ventilation state, V'CO2 kg-1 has good predictive ability.

In this study, we investigate the impact of bystander relation and medical training on survival to hospital discharge in out-of-hospital cardiac arrest (OHCA) patients receiving bystander cardiopulmonary resuscitation (CPR). ⋯ This study supports ongoing efforts to crowdsource a larger number of first responders with medical training to OHCA patients to assist with the provision of CPR and early defibrillation.
