The optimal head and thorax position after return of spontaneous circulation (ROSC) following cardiac arrest (CA) is unknown. This study examined whether head and thorax elevation post-ROSC is beneficial, in a porcine model. ⋯ 19-09.

Randomized Controlled Trial Multicenter Study
NSE as a Predictor of Death or Poor Neurological Outcome after Non-Shockable Cardiac Arrest Due to Any Cause: Ancillary Study of HYPERION Trial Data.
Prognostication of hypoxic-ischaemic brain injury after resuscitation from cardiac arrest is based on a multimodal approach including biomarker assays. Our goal was to assess whether plasma NSE helps to predict day-90 death or poor neurological outcome in patients resuscitated from cardiac arrest in non-shockable rhythm. ⋯ ClinicalTrial NCT02722473.

Randomized Controlled Trial Multicenter Study
Mechanical versus manual chest compressions in the treatment of in-hospital cardiac arrest patients in a non-shockable rhythm: a multi-centre feasibility randomised controlled trial (COMPRESS-RCT).
Mechanical chest compression devices deliver high-quality chest compressions. Early data suggests that mechanical devices may be superior to manual chest compressions in adults following an in-hospital cardiac arrest patients. To determine the feasibility of undertaking an effectiveness trial in this population, we undertook a feasibility randomised controlled trial. ⋯ COMPRESS-RCT identified important factors that preclude progression to an effectiveness trial of mechanical CPR in the hospital setting in the UK. Findings will inform the design of future in-hospital intra-arrest intervention trials. ISRCTN38139840, date of registration 9th January 2017.

Randomized Controlled Trial
The Effect of Airway Management on CPR Quality in the Paramedic2 Randomised Controlled Trial.
Good quality basic life support (BLS) is associated with improved outcome from cardiac arrest. Chest compression fraction (CCF) is a BLS quality indicator, which may be influenced by the type of airway used. We aimed to assess CCF according to the airway strategy in the PARAMEDIC2 study: no advanced airway, supraglottic airway (SGA), tracheal intubation, or a combination of the two. Our hypothesis was that tracheal intubation was associated with a decrease in the CCF compared with alternative airway management strategies. ⋯ There was no significant difference in the compression fraction associated with the airway management strategy.

Randomized Controlled Trial
The Design of an Adaptive Clinical Trial to Evaluate the Efficacy of Extra-Corporeal Membrane Oxygenation for Out-of-Hospital Cardiac Arrest.
Extracorporeal cardiopulmonary resuscitation (ECPR) is a promising therapy for out-of-hospital cardiac arrest (OHCA) that is refractory to standard therapy, but no multicenter randomized clinical trials have been conducted to establish its efficacy. We report the design and operating characteristics of a proposed randomized Bayesian adaptive "enrichment" clinical trial designed to determine whether ECPR is effective for refractory OHCA and, if effective, to define the interval after arrest during which patients derive benefit. ⋯ This proposed adaptive trial design helps to ensure the population of patients who are most likely to benefit from treatment-as defined both by rhythm subgroup and estimated CA-to-ECPR interval-is enrolled. The design promotes early termination of the trial if continuation is likely to be futile.
