Randomized Controlled Trial Comparative Study
Resuscitation quality of rotating chest compression providers at one-minute vs. two-minute intervals: A mannequin study.
The aim of this randomized cross-over study was to compare one-minute and two-minute continuous chest compressions in terms of chest compression only CPR quality metrics on a mannequin model in the ED. ⋯ There was no statistically significant difference in the quality metrics of chest compressions between 1- and 2-minute chest compression only groups.

The role of circulatory support in the post-cardiac arrest period remains controversial. Our objective was to investigate the association between treatment with a percutaneous hemodynamic support device and outcome after admission for cardiac arrest. ⋯ Treatment with percutaneous hemodynamic support device in the post-arrest period may provide left ventricular support and improve outcome.

Comparative Study
Monitoring the corrected QT in the acute care setting: A comparison of the 12‑lead electrocardiogram and bedside monitor.
Prolongation of the QT interval is a well-recognized complication associated with many commonly used medications. Emergency Department monitoring of the corrected QT (QTc) both before and after medication administration is typically performed using the 12‑lead electrocardiogram (ECG). The purpose of this study is to compare the QTc reported on the 12‑lead ECG to that reported by single brand of bedside monitor. ⋯ We found that there was moderate correlation between the QTc reported on the 12 lead ECG and that reported by the bedside monitor. This correlation is not strong enough to support the use of the bedside monitor as a substitute for the 12‑lead ECG when evaluating a patient's QTc.

Observational Study
A prospective study of ketamine as primary therapy for prehospital profound agitation.
We investigated the effectiveness of ketamine as a primary therapy for prehospital profound agitation. ⋯ In patients with prehospital profound agitation, ketamine provides rapid effective sedation when used as a primary therapy. Intubation was common but accompanied by a short duration of mechanical ventilation and appears to have been subject to individual physician practice variation.
