Randomized Controlled Trial
Elimination of Glutamate using CRRT for 72 hours in patients with post-cardiac arrest syndrome: a randomized clinical pilot trial.
Glutamine and glutamate are major mediators of secondary brain cell death during post-cardiac arrest syndrome. As there is an equilibrium between brain tissue and plasma concentrations of glutamine and glutamate, their elimination from systemic circulation by extracorporeal blood purification may ultimately lead to reduced secondary cell death in the brain. We hypothesized that systemic glutamine and glutamate can be significantly reduced by continuous venovenous hemodiafiltration (CVVHDF). ⋯ In this trial, CVVHDF was not able to statistically significantly lower systemic plasma glutamine and glutamate levels. Post-cardiac arrest patients had plasma glutamine and glutamate levels within the normal range.

Utstein-style reporting templates provide a structured framework with which to compare systems of care for cardiac arrest. The 2004 Utstein reporting template encompassed both out-of-hospital and in-hospital cardiac arrest. A 2015 update of the Utstein template focused on out-of-hospital cardiac arrest, which makes this update of the in-hospital template timely. ⋯ Variables were described as core if they were considered essential. Core variables should enable reasonable comparisons between systems and are considered essential for quality improvement programs. Together with core variables, supplementary variables are considered useful for research.

This study aimed to assess whether team-based cardiopulmonary resuscitation (CPR) training for emergency medical service (EMS) providers improved the pre-hospital return of spontaneous circulation (ROSC) rates of non-traumatic adult out-of-hospital cardiac arrest (OHCA) patients. ⋯ Team-based CPR training for EMS providers in a large community EMS system improved the pre-hospital ROSC rates of OHCA patients.

Observational Study
Extracorporeal membrane oxygenation improves outcomes of accidental hypothermia without vital signs: a nationwide observational study.
Patients with accidental hypothermia without vital signs increasingly receive venoarterial extracorporeal membrane oxygenation (VA-ECMO). However, there is limited knowledge regarding the efficacy of this advanced rewarming method. We aimed to determine whether VA-ECMO improved outcomes in patients with accidental hypothermia without vital signs, using a large nationwide inpatient database in Japan. ⋯ VA-ECMO was associated with higher survival and favourable neurological outcomes compared with conventional CPR alone in patients with accidental hypothermia without vital signs.

Use of smart devices to provide real-time cardiopulmonary resuscitation (CPR) feedback in the context of out-of-hospital cardiac arrest (OHCA) has considerable potential for improving survival. However, the findings of previous studies evaluating the effectiveness of these devices have been conflicting. Therefore, we conducted a systematic review of the literature to assess the utility of smart devices for improving the quality of CPR during CPR training. ⋯ This review does not find durable evidence for usefulness of smart devices in CPR training. However, the smartwatches may improve the accuracy of chest compression depth. Future studies with larger sample sizes might be necessary before reaching a firm conclusion.
