The authors determined if E-point septal separation (EPSS) as measured by junior emergency physicians (EPs) correlated with visual estimation of left ventricle ejection fraction (LVEF) by senior EPs and cardiologists in acutely dyspneic patients presenting to an adult emergency department (ED). ⋯ In this study, junior EPs were able to obtain measurements of EPSS that correlated closely with visual estimates of LVEF by clinicians with extensive point-of-care and comprehensive echocardiography experience.

Ethics seminar: the hospice patient in the ED: an ethical approach to understanding barriers and improving care.
Emergency physicians (EPs) are asked to evaluate and treat a growing population of hospice patients who present to the emergency department (ED) for a number of important reasons. Hospice patients pose unique ethical challenges, and "best practices" for these patients can differ from the life-preserving interventions of usual ED care. Having a solid understanding of professional responsibilities and ethical principles is useful for guiding EP management of these patients. ⋯ This article describes the case of a hospice patient who presented with sepsis and end-stage cancer to the ED. Patient, system, and physician factors made management decisions in the ED difficult. The goal in the ED should be to determine the best way to address terminally ill patient needs while respecting wishes to limit interventions that will only increase suffering near the end of life.

During a series of reforms to the Tennessee Medicaid expansion program (TennCare) in 2005, approximately 171,000 adults were disenrolled from Medicaid. The objective of this study was to examine the statewide effect of such a disenrollment on Tennessee emergency department (ED) utilization. ⋯ The TennCare disenrollment of 2005 was associated with a modest decrease in the number of total ED visits in Tennessee. However, the payer mix among the Tennessee ED population shifted abruptly. The increased rate of ED visits by Tennessee's uninsured and the increased proportion of uninsured ED visits leading to hospital admission suggest an increased burden of illness in this highly vulnerable population.

L-carnitine is an essential compound involved in cellular energy production through free fatty acid metabolism. It has been theorized that severe verapamil toxicity "shifts" heart energy production away from free fatty acids and toward other sources, contributing to profound cardiogenic shock. The primary study objective was to determine whether intravenous (IV) L-carnitine affects survival in severe verapamil toxicity. Secondary objectives were to determine the effects on hemodynamic parameters. The authors hypothesized that IV L-carnitine would increase both survival and hemodynamic parameters in severe verapamil toxicity. ⋯ When compared with saline, IV L-carnitine increases survival and MAP in a murine model of severe verapamil toxicity.
