Randomized Controlled Trial Comparative Study Observational Study
The Dispatcher Assisted Resuscitation Trial: Indirect Benefits of Emergency Research.
Conduct of emergency research under waiver of consent produces special challenges. Moreover, the act of performing research may have unintended effects, potentially beneficial or detrimental. The Dispatcher-Assisted Randomized Trial (DART) was designed to compare 2 types of dispatcher cardiopulmonary (CPR) instruction, but not intended to affect the proportion of arrest victims that received bystander CPR. We sought to determine whether odds of receiving bystander CPR were higher during DART than during the periods before and after. ⋯ Odds of bystander CPR were higher during the trial, an increase related to higher likelihood of DA-CPR. The finding suggests a possible indirect community-wide benefit due to the interventional trial.

Randomized Controlled Trial Multicenter Study Comparative Study
The inflammatory response after out-of-hospital cardiac arrest is not modified by targeted temperature management at 33°C or 36°C.
Survivors after cardiac arrest (CA) exhibits a systemic inflammatory response as part of post-cardiac arrest syndrome (PCAS). We investigated the association between systemic inflammation and severity of PCAS and whether level of targeted temperature management (TTM) modifies level of the inflammatory response. ⋯ Level of inflammatory response was associated with severity of PCAS with IL-6 being consistently and more strongly associated with severity of PCAS than the inflammatory markers CRP and PCT. The systemic inflammatory response after CA was not modified by TTM at 33 °C or 36 °C.

Randomized Controlled Trial
Randomised trial comparing the recording ability of a novel, electronic emergency documentation system with the AHA paper cardiac arrest record.
To evaluate the ability of an electronic system created at the University of Washington to accurately document prerecorded VF and pulseless electrical activity (PEA) cardiac arrest scenarios compared with the American Heart Association paper cardiac arrest record. ⋯ Compared with paper documentation, documentation with the electronic system captured 24% more critical information during a simulated medical emergency without loss in data quality.

The Impact of Ultra-Brief Chest Compression-Only CPR Video Training on Responsiveness, Compression Rate, and Hands-Off Time Interval Among Bystanders in a Shopping Mall.
Recent studies have demonstrated higher-quality chest compressions (CCs) following a 60 s ultra-brief video (UBV) on compression-only CPR (CO-CPR). However, the effectiveness of UBVs as a CPR-teaching tool for lay bystanders in public venues remains unknown. ⋯ Bystanders with UBV training in a shopping mall had significantly improved responsiveness, CC rate, and decreased hands-off interval. Given the short length of training, UBV may have potential as a ubiquitous intervention for public venues to help improve bystander reaction to arrest and CO-CPR performance.

Regional cerebral oxygen saturation after cardiac arrest in 60 patients-A prospective outcome study.
Non-invasive near-infrared spectroscopy (NIRS) offers the possibility to determine regional cerebral oxygen saturation (rSO2) in patients with cardiac arrest. Limited data from recent studies indicate a potential for early prediction of neurological outcome. ⋯ On average, rSO2 within the first 40h after ROSC is significantly lower in patients with poor outcome, but rSO2 ranges largely overlap between outcome groups. Our data indicate limited potential for prediction of poor outcome by frontal brain rSO2 measurements.
