Randomized Controlled Trial
Diagnostic accuracy of ultrasound to confirm endotracheal tube depth.
Endotracheal intubation is commonly performed in the Emergency Department. Traditional measures for estimating and confirming the endotracheal tube (ETT) depth may be inaccurate or lead to delayed recognition. Ultrasound may offer a rapid tool to confirm ETT depth at the bedside. ⋯ Ultrasound was moderately accurate for identifying the ETT location in a cadaveric model and was more accurate when sonographers felt confident with their visualization. Future research should determine the accuracy of combining transtracheal ultrasound with lung sliding and other modifications to improve the accuracy.

Atrial fibrillation (Afib) with rapid ventricular response (RVR) is acutely treated with intravenous push (IVP) metoprolol (MET) or diltiazem (DIL). In heart failure (HF) patients, diltiazem is not recommended due to negative inotropic effects. Studies comparing the treatment of atrial fibrillation often exclude HF. Hirschy et al. evaluated HF patients with concomitant Afib with RVR who received IVP metoprolol or diltiazem to determine their effectiveness and safety. They found similar safety and effectiveness outcomes between the two groups. ⋯ Acute management of patients with Afib with RVR and HF is challenging. While successful rate control at 30 min was not significantly different between diltiazem and metoprolol, IVP diltiazem reduced HR more quickly and reduced HR by 20% or greater more frequently than IVP metoprolol with no safety outcome differences. Further studies are needed to evaluate diltiazem's safety in patients with Afib and HF.

Observational Study
Trauma center designation level and survival of patients with chest wall instability.
Chest wall instability is a potentially life-threatening condition that should be evaluated at a trauma center. While patients with chest wall instability are sent to different trauma center levels, the impact of this on outcomes has not been evaluated yet. This study examines survival to hospital discharge of patients with chest wall instability treated at different trauma center levels. ⋯ Survival rates for patients having chest wall instability were similar when transported to level II or level III versus level I centers. This finding can help guide pre-hospital field triage criteria for this specific type of injury and highlights the need for more outcome research in organized trauma systems.
