The presentation of PE is often subtle and may mimic other diseases. Many pulmonary emboli invariably preclude diagnosis by their occult nature or by leading to rapid death from cardiopulmonary arrest. In patients who do manifest symptoms from PE, accurate diagnosis is essential. Often it is difficult to distinguish the vague symptoms of PE from other(More)
INTRODUCTION Despite a relatively high frequency of appendix nonvisualization when using ultrasound to diagnose appendicitis, many studies either fail to report these results or inconsistently analyze outcomes. OBJECTIVES The objective of this study is to determine the most transparent and accurate way of reporting and analyzing ultrasound results for the(More)
OBJECTIVES The objective was to compare the image quality, diagnostic accuracy, radiation exposure, and contrast volume of "triple rule-out" (TRO) computed tomography (CT) to other diagnostic modalities commonly used to evaluate patients with nontraumatic chest pain (dedicated coronary, pulmonary embolism [PE], and aortic dissection CT; invasive coronary(More)
BACKGROUND Quality-improvement efforts at our institution have identified chest tube dislodgement as a preventable complication of tube thoracostomy. Because proper fixation techniques are not well described in the literature and are seldom formally taught, techniques vary among residents. OBJECTIVE Our aim was to develop and test a framework for teaching(More)
INTRODUCTION The transition from medical student to intern is inherently stressful, with potentially negative consequences for both interns and patients. METHODS We describe Internship Boot Camp, an innovative course specifically designed to prepare fourth-year medical students for the transition from medical school to internship. An intensive 1-week(More)
Developing technical expertise in medical procedures is an integral component of emergency medicine (EM) practice and training. This article is the work of an expert panel composed of members from the Society for Academic Emergency Medicine (SAEM) Interest Group, the SAEM Technology in Medical Education Committee, and opinions derived from the May 2008(More)
Health care simulation includes a variety of educational techniques used to complement actual patient experiences with realistic yet artificial exercises. This field is rapidly growing and is widely used in emergency medicine (EM) graduate medical education (GME) programs. We describe the state of simulation in EM resident education, including its role in(More)
BACKGROUND Computed tomography (CT) is the primary source of nontherapeutic medical radiation exposure. Radiation exposure is associated with an increased risk of cancer mortality. Although the risk of cancer mortality is negligible in comparison with that of trauma mortality in high-risk patients, the balance of risk versus benefit in patients with less(More)
STUDY OBJECTIVES We determine the effect of pressure immobilization on mortality and intracompartmental pressure after artificial intramuscular Crotalus atrox envenomation in a porcine model. METHODS We prospectively studied 20 pigs using a randomized, controlled design. After anesthesia, C atrox venom (20 mg/kg) was injected with a 22-gauge needle 10 mm(More)
INTRODUCTION The Central Line Workshop (CLW) was introduced at our institution to better train residents in safe placement of the central venous catheter (CVC). This study sought to determine if immediate performance improvements from the CLW are sustained 3 months after the training for residents with various levels of experience. METHODS Twenty-six(More)
