Randomized Controlled Trial
Biomarker prognostication of cognitive impairment may be feasible even in out-of hospital cardical arrest survivors with good neurological outcome.
Patients surviving out-of hospital cardicac arrest, with good neurological outcome according to Cerebral Performance Category, frequently have neuropsychological impairment. We studied whether biomarker data (S-100b and neuron-specific enolase) obtained during the ICU stay predicted cognitive impairment 6 months after resuscitation. ⋯ Early biomarker prognostication of cognitive impairment is feasible even in OHCA survivors with good neurological outcome as defined by CPC. NSE at 48 h predicted cognitive impairment.

Pragmatic Clinical Trial
Airway Strategy and Chest Compression Quality in the Pragmatic Airway Resuscitation Trial.
Chest compression (CC) quality is associated with improved out-of-hospital cardiopulmonary arrest (OHCA) outcomes. Airway management efforts may adversely influence CC quality. We sought to compare the effects of initial laryngeal tube (LT) and initial endotracheal intubation (ETI) airway management strategies upon chest compression fraction (CCF), rate and interruptions in the Pragmatic Airway Resuscitation Trial (PART). ⋯ In the PART trial, compared with ETI, LT was associated with shorter total CC interruption duration but not other CC quality measures. CC quality may be associated with OHCA airway management.

Targeted Temperature Management (TTM) reduces mortality and improves neurological outcomes after cardiac arrest. Cardiac arrest is considered a pro-thrombotic state. Endovascular cooling catheters may increase the risk of thrombosis. Targeted Temperature Management, however, increases fibrinolysis. The net outcome of these opposing effects remains largely unexplored. Moreover, the exact rate of venous thromboembolism (VTE) is uncertain in these patients. We sought to determine the incidence and potential predictors of VTE in patients undergoing TTM. ⋯ Patients undergoing TTM after cardiac arrest have statistically higher incidence of VTE and DVT compared to patients with ARDS. This risk is independent of age, gender, race or length of stay.

Observational Study
Bystander Interventions and Survival Following Out-of-Hospital Cardiac Arrest at Copenhagen International Airport.
To examine incidence and outcome following out-of-hospital cardiac (OHCA) arrest in a high-risk area characterised by high density of potential bystanders and easy access to nearby automated external defibrillators (AEDs). ⋯ We found a high proportion of bystander defibrillation indicating that bystanders will quickly apply an AED, when accessible. Importantly, 56% of all persons, and all persons with a shockable heart rhythm survived. These findings suggest increased potential for survival following OHCA and support current guidelines to strategically deploy accessible AEDs in high-risk OHCA areas.
