Outcomes of conventional cardiopulmonary resuscitation are improved when the initial rhythm is shockable (ventricular fibrillation or pulseless ventricular tachycardia). In children, the first documented rhythm is typically asystole or pulseless electrical activity. We evaluate the role the initial rhythm plays in outcomes for children undergoing extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital cardiac arrest. ⋯ In children with in-hospital cardiac arrest undergoing ECPR, there was no significant difference in survival or favorable neurologic outcome between those with initial shockable rhythm compared to non-shockable rhythm. Further investigation to evaluate ECPR patient characteristics and outcomes is warranted to help guide eligibility and ECMO deployment practices.

Out-of-hospital cardiac arrest (OHCA) contributes to substantial mortality, but its resuscitation status in China is unknown. We aimed to describe and analyze out-of-hospital cardiac arrest in terms of Chain of Survival. ⋯ A low probability of first aid at multiple points is linked to poor survival following OHCA. It is essential to strengthen front links in the Chain of Survival in China, including among witnesses, bystanders, and emergency response.

Randomized Controlled Trial
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.

Randomized Controlled Trial
Cardiovascular changes induced by targeted mild hypercapnia after out of hospital cardiac arrest. A sub-study of the TAME cardiac arrest trial.
Hypercapnia may elicit detrimental haemodynamic effects in critically ill patients. We aimed to investigate the consequences of targeted mild hypercapnia versus targeted normocapnia on pulmonary vascular resistance and right ventricular function in patients resuscitated from out-of-hospital cardiac arrest (OHCA). ⋯ In resuscitated OHCA patients, targeting mild hypercapnia did not increase PVRI or worsen right ventricular function compared to normocapnia. Mild hypercapnia comparatively improved cardiac performance and mixed venous oxygen saturation.
