Review Case Reports
Nasogastric aspiration and lavage in emergency department patients with hematochezia or melena without hematemesis.
The utility of nasogastric aspiration and lavage in the emergency management of patients with melena or hematochezia without hematemesis is controversial. This evidence-based emergency medicine review evaluates the following question: does nasogastric aspiration and lavage in patients with melena or hematochezia and no hematemesis differentiate an upper from lower source of gastrointestinal (GI) bleeding? ⋯ Nasogastric aspiration, with or without lavage, has a low sensitivity and poor negative likelihood ratio, which limits its utility in ruling out an upper GI source of bleeding in patients with melena or hematochezia without hematemesis.

Review Meta Analysis
Does the early administration of beta-blockers improve the in-hospital mortality rate of patients admitted with acute coronary syndrome?
Beta-blockade is currently recommended in the early management of patients with acute coronary syndromes (ACS). This was a systematic review of the medical literature to determine if early beta-blockade improves the outcome of patients with ACS. ⋯ This systematic review failed to demonstrate a convincing in-hospital mortality benefit for using beta-blockers early in the course of patients with an acute or suspected MI.

Review Comparative Study
Sensitivity of bedside ultrasound and supine anteroposterior chest radiographs for the identification of pneumothorax after blunt trauma.
Supine anteroposterior (AP) chest radiographs in patients with blunt trauma have poor sensitivity for the identification of pneumothorax. Ultrasound (US) has been proposed as an alternative screening test for pneumothorax in this population. The authors conducted an evidence-based review of the medical literature to compare sensitivity of bedside US and AP chest radiographs in identifying pneumothorax after blunt trauma. ⋯ This evidence-based review suggests that bedside thoracic US is a more sensitive screening test than supine AP chest radiography for the detection of pneumothorax in adult patients with blunt chest trauma.

The purpose of this article is to highlight medical education research studies published in 2008 that were methodologically superior and whose outcomes were pertinent to teaching and education in emergency medicine. ⋯ This review highlights quality medical education research studies published in 2008, with outcomes of relevance to teaching and education in emergency medicine. It focuses on research methodology, notes current trends in the use of technology for learning in emergency medicine, and suggests future avenues for continued rigorous study in education.

As the specialty of emergency medicine (EM) continues to evolve in countries around the world, and as interest in international emergency medicine (IEM) continues to grow within the United States, the IEM Literature Review Group recognizes a need for a high-quality, consolidated, and easily accessible evidence base of literature. In response to that need, the group created an annual publication that strives to provide readers with access to the highest quality and most relevant IEM research. ⋯ Articles were selected for the review according to explicit, predetermined criteria that include both methodologic quality and perceived impact of the research. It is our hope that this annual review will act as a forum for disseminating best practices while also stimulating further research in the field of IEM.
