Randomized Controlled Trial
The Effect of Intravenous Adrenaline on Electrocardiographic Changes During Resuscitation in Patients with Initial Pulseless Electrical Activity in Out of Hospital Cardiac Arrest.
Presence of electrocardiographic rhythm in the absence of palpable pulses defines pulseless electrical activity (PEA) and the electrocardiogram (ECG) may provide a source of information during resuscitation. The aim of this study was to examine the development of ECG characteristics during advanced life support (ALS) from Out-of-hospital cardiac arrest (OHCA) with initial PEA, and to explore the potential effects of adrenaline on these characteristics. ⋯ ECG changes during ALS in cardiac arrest were associated with prognosis, and the administration of adrenaline impacted on these changes.

Randomized Controlled Trial
Wireless and continuous monitoring of vital signs in patients at the general ward.
Clinical deterioration regularly occurs in hospitalized patients potentially resulting in life threatening events. Early warning scores (EWS), like the Modified Early Warning Score (MEWS), assist care givers in assessing patients' clinical situation, but cannot alert for deterioration between measurements. New devices, like the ViSi Mobile (VM) and HealthPatch (HP) allow for continuous monitoring and can alert deterioration in an earlier phase. VM and HP were tested regarding MEWS calculation compared to nurse measurements, and detection of high MEWS in periods between nurse observations. ⋯ Both VM and HP are promising for continuous vital sign monitoring and may be more accurate than nurses. High MEWS can be detected in hospitalized patients around the clock and clinical deterioration at an earlier phase during unobserved periods.

Randomized Controlled Trial
Optimal training frequency for acquisition and retention of high-quality CPR skills: A randomized trial.
Spaced training programs employ short, frequent CPR training sessions to improve provider skills. The optimum training frequency for CPR skill acquisition and retention has not been determined. We aimed to determine the training interval associated with the highest quality CPR performance at one year. ⋯ Short-duration, distributed CPR training on a manikin with real-time visual feedback is effective in improving CPR performance, with monthly training more effective than training every 3, 6, or 12 months.

Randomized Controlled Trial Multicenter Study
Variations in the application of exception from informed consent in a multicenter clinical trial.
Exception from infor med consent (EFIC) is allowed using federal regulations 21 CFR 50.24 and facilitates research on patients with critical conditions such as cardiac arrest. Little is known regarding the differences in the application of EFIC requirements such as community consultation (CC), public disclosure (PD) and patient notification. We sought to characterize variations in the fulfillment of EFIC requirements in a national multicenter clinical trial in the United States. ⋯ EFIC implementation varies across sites and highlight community and regional variation. Different EFIC approaches may be needed to effectively accomplish the goals of community consultation, public disclosure, and patient notification.

Randomized Controlled Trial
Post resuscitation prognostication by EEG in 24 vs 48 hours of targeted temperature management.
To test if prognostic performance is affected by prolonged targeted temperature management (TTM) in comatose out-of-hospital cardiac arrest patients using two recently proposed EEG pattern classification models. ⋯ We found no difference in the prognostic performance of the two studied EEG classification models during prolonged TTM for 48 h compared to standard duration, nor between EEG classification performed at 24 h versus 48 h after reaching target temperature. The two models performed best in good outcome prediction.
