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.

Multicenter Study
Bougie-Assisted Endotracheal Intubation in the Pragmatic Airway Resuscitation Trial.
Paramedics may perform endotracheal intubation (ETI) while treating patients with out-of-hospital cardiac arrest (OHCA). The gum elastic Bougie (Bougie) is an intubation adjunct that may optimize intubation success. There are few reports of Bougie-assisted intubation in OHCA nor its association with outcomes. We compared intubation success rates and OHCA outcomes between Bougie-assisted and non-Bougie ETI in the out-of-hospital Pragmatic Airway Resuscitation Trial (PART). ⋯ While exhibiting slightly higher ETI overall success rates, Bougie-assisted ETI entailed longer airway placement times and potentially lower survival. The role of the Bougie assistance in ETI of OHCA remains unclear.

Multicenter Study Observational Study
Non-linear association between arterial oxygen tension and survival after out-of-hospital cardiac arrest: a multicentre observational study.
Studies to identify safe oxygenation targets after out-of-hospital cardiac arrest (OHCA) have often assumed a linear relationship between arterial oxygen tension (PaO2) and survival, or have dichotomised PaO2 at a supra-physiological level. We hypothesised that abnormalities in mean PaO2 (both high and low) would be associated with decreased survival after OHCA. ⋯ The mean PaO2 within the first 24-hs after admission for OHCA has a non-linear association with the highest STHD seen between 100 and 180 mmHg. Randomised controlled trials are now needed to validate the optimal oxygenation targets in mechanically ventilated OHCA patients.

Multicenter Study
Influence of the Covid-19 pandemic on out-of-hospital cardiac arrest. A Spanish nationwide prospective cohort study.
The influence of the COVID-19 pandemic on attendance to out-of-hospital cardiac arrest (OHCA) has only been described in city or regional settings. The impact of COVID-19 across an entire country with a high infection rate is yet to be explored. ⋯ ISRCTN10437835.

Multicenter Study
Evidence-based crisis standards of care for out-of-hospital cardiac arrests in a pandemic.
Pandemics such as COVID-19 can lead to severe shortages in healthcare resources, requiring the development of evidence-based Crisis Standard of Care (CSC) protocols. A protocol that limits the resuscitation of out-of-hospital cardiac arrests (OHCA) to events that are more likely to result in a positive outcome can lower hospital burdens and reduce emergency medical services resources and infection risk, although it would come at the cost of lives lost that could otherwise be saved. Our primary objective was to evaluate candidate OHCA CSC protocols involving known predictors of survival and identify the protocol that results in the smallest resource burden, as measured by the number of hospitalizations required per favorable OHCA outcome achieved. Our secondary objective was to describe the effects of the CSC protocols in terms of health outcomes and other measures of resource burden. ⋯ In a pandemic scenario, pre-hospital CSC protocols that might not otherwise be considered have the potential to greatly improve overall survival, and this study provides an evidence-based approach towards selecting such a protocol. As this study was performed using data generated before the COVID-19 pandemic, future studies incorporating pandemic-era data will further help develop evidence-based CSC protocols.
