Observational Study
Reasons for death in patients successfully resuscitated from out-of-hospital and in-hospital cardiac arrest.
There is no standard for categorizing reasons for death in those who achieve return of spontaneous circulation (ROSC) after cardiac arrest but die before hospital discharge. Categorization is important for comparing outcomes across studies, assessing benefits of interventions, and developing quality-improvement initiatives. We developed and tested a method for categorizing reasons for death after cardiac arrest in both in-hospital (IHCA) and out-of-hospital (OHCA) arrests. ⋯ Categorizing reasons for death after cardiac arrest with ROSC is feasible using our proposed categories, with substantial inter-rater agreement. Neurologic withdrawal of care is much less common in IHCA than OHCA, which may have implications for further research.

Effectiveness of Intubating Laryngeal Mask Airway in managing out-of-hospital cardiac arrest by non-physicians.
The role of supraglottic devices in airway management in out-of-hospital cardiac arrest (OHCA) remains controversial. The aim of this study was to evaluate the feasibility and effectiveness of intubation through the Intubating Laryngeal Mask Airway (ILMA) when used by prehospital emergency nurses in the setting of OHCA. ⋯ The success rate of intubation through the ILMA was high. After ILMA placement, ventilation was possible in 1250 patients (85.38%) and in 1078 patients (73.63%) after intubation.

Extracorporeal cardiopulmonary resuscitation (ECPR) is the emerging resuscitative strategy to save refractory ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) patients. We investigated whether the receiving hospitals' ECPR capabilities are associated with outcomes in out-of-hospital cardiac arrest (OHCA) patients who have refractory VF or pulseless VT. ⋯ Hospitals' ECPR capabilities were associated with favourable neurologic outcomes in OHCA patients who had refractory VF or pulseless VT. We should take each hospital's ECPR capability into consideration when developing a regional system of care for OHCA.

Observational Study
Time to achieve desired fraction of inspired oxygen using a T-piece ventilator during resuscitation of preterm infants at birth.
To determine the time between adjustment of FiO2 at the oxygen blender and the desired FiO2 reaching the preterm infant during respiratory support at birth. ⋯ There is a clear delay before a desired FiO2 is achieved at the distal end of the T-piece resuscitator. This delay is clinically relevant as this delay could easily lead to over- and under titration of oxygen, which might result in an increased risk for both hypoxia and hyperoxia.

Automated external defibrillator accessibility is crucial for bystander defibrillation and survival: A registry-based study.
Optimization of automated external defibrillator (AED) placement and accessibility are warranted. We examined the associations between AED accessibility, at the time of an out-of-hospital cardiac arrest (OHCA), bystander defibrillation, and 30-day survival, as well as AED coverage according to AED locations. ⋯ The chance of a bystander defibrillation was tripled, and 30-day survival nearly doubled, when the nearest AED was accessible, compared to inaccessible, at the time of OHCA, underscoring the importance of unhindered AED accessibility.
