Volar metacarpal phalangeal joint dislocations are rare injuries. We could find only eight cases reported, with none in the emergency medicine literature. We present a case report and describe the biomechanics and radiographic findings of this injury.

Randomized Controlled Trial Comparative Study Clinical Trial
The esophageal detector device: a rapid and accurate method for assessing tracheal versus esophageal intubation in a porcine model.
To assess time and accuracy of the esophageal detector device (EDD), disposable end-tidal CO2 monitor (ETCO2), and standard clinical methods for detection of endotracheal tube placement. ⋯ In this porcine model, the EDD and ETCO2 were more accurate than clinical methods in determining endotracheal tube placement. The EDD demonstrated a significant time advantage over both ETCO2 and clinical methods. Prior ventilation of the esophageal tube does not interfere with the accuracy of the EDD.

To describe the epidemiology of cardiac arrest in young adults and to determine if there are characteristics unique to this group in terms of etiology, rhythm, and outcome. ⋯ In terms of age, etiology, and rhythm, young adults appear to represent a transitional group between children and older adults.

To demonstrate the technique of selective aortic arch perfusion during cardiac arrest and to observe the hemodynamic effects of volume infusion and aortic epinephrine administration. ⋯ Selective aortic arch perfusion is technically feasible, but excessive right atrial pressure increases limit maximal infusion rates and volumes. Selective aortic arch perfusion infusates with epinephrine produce greater midaortic arch pressure and coronary perfusion pressure during infusion than infusate without epinephrine. Controlled studies are needed to determine if selective aortic arch perfusion improves resuscitation outcome.

To assess the effect of a 33% coronary stenosis on myocardial blood flow during normal sinus rhythm and CPR. ⋯ Minimal coronary lesions that do not diminish myocardial perfusion during normal physiologic conditions appear to significantly decrease subendocardial blood flow during cardiac arrest and CPR.
