Randomized Controlled Trial
Extracorporeal Cardiopulmonary Resuscitation-Based Approach to Refractory Out-of-Hospital Cardiac Arrest: a Focus on Organ Donation, a Secondary Analysis of a Prague OHCA Randomized Study.
Refractory out-of-hospital cardiac arrest (OHCA) has a poor outcome. In patients, who cannot be rescued despite using advanced techniques like extracorporeal cardiopulmonary resuscitation (ECPR), organ donation may be considered. This study aims to evaluate, in refractory OHCA, how ECPR versus a standard-based approach allows organ donorship. ⋯ The ECPR-based approach in the refractory OHCA trial is associated with increased organ donorship and an excellent outcome of transplanted organs.

The Effects of Mechanical Versus Bag-Valve Ventilation on Gas Exchange During Cardiopulmonary Resuscitation in Emergency Department Patients: A Randomized Controlled Trial (CPR-VENT).
Effective ventilation is crucial for successful cardiopulmonary resuscitation (CPR). Previous studies indicate that higher arterial oxygen levels (PaO2) during CPR increase the chances of successful resuscitation. However, the advantages of mechanical ventilators over bag-valve ventilation for achieving optimal PaO2 during CPR remain uncertain. ⋯ In ED patients with refractory cardiac arrest, arterial oxygen levels during CPR were comparable between patients ventilated with MV and BV. Mechanical ventilation is at least feasible and safe during CPR in intubated cardiac arrest patients.

Advances in vertical take-off and landing (VTOL) technologies may enable drone-like crewed air ambulances to rapidly respond to out-of-hospital cardiac arrest (OHCA) in urban areas. We estimated the impact of incorporating VTOL air ambulances on OHCA response intervals in two large urban centres in France and Canada. ⋯ VTOL air ambulances dedicated to OHCA response may improve EMS response intervals, with substantial improvements in ALS response metrics.

Rapid response teams (RRTs) are designed to improve the "chain of prevention" of in-hospital cardiac arrest (IHCA). We studied the 30-day survival of patients reviewed by RRTs within 24 hours prior to IHCA, as compared to patients not reviewed by RRTs. ⋯ IHCA preceded by RRT review is associated with a lower 30-day survival rate and a greater likelihood of a respiratory cause of cardiac arrest. In the small explorative subgroup, respiratory distress was the most common RRT trigger and delayed RRT activation was frequent. Early detection of respiratory abnormalities and timely interventions may have a potential to improve outcomes in RRT-reviewed patients and prevent further progress into IHCA.

Extracorporeal cardiopulmonary resuscitation (ECPR) has been shown to improve neurologically favorable survival for patients with refractory ventricular tachycardia (VT)/ventricular fibrillation (VF) out-of-hospital cardiac arrest. Prior studies of the impact of age on outcomes in ECPR have demonstrated mixed results and we aim to investigate this relationship. ⋯ Age is associated with neurologically favorable survival to discharge for patients receiving ECPR for refractory out-of-the-hospital VT/VF cardiac arrest. However, with a survival rate of 23% in the oldest age group, caution should be used when choosing age criteria for patient selection.
