Studies have shown that vein size is an important predictor of successful ultrasound-guided vascular access. The objective of this study is to evaluate maneuvers designed to increase basilic vein size, which could be used to facilitate ultrasound-guided peripheral intravenous access (USGPIV) in the Emergency Department (ED) setting. ⋯ The largest increase in basilic vein size was due to blood pressure cuff inflation. BP cuff inflation resulted in a statistically significant increase in vein size compared to tourniquet application, but this difference may not be clinically significant.

Abdominal computed tomography scan (CT) is the preferred radiographic study for the diagnosis of appendicitis in the United States, while radiologist-operated ultrasound (US) is often used in Israel. This comparative international study evaluates the performance of CT vs. US in the evaluation of acute appendicitis. ⋯ Radiologist-operated US had inferior sensitivity and positive predictive value when compared with CT, though was significantly faster to perform, and avoided radiation and contrast in a majority of patients. A "first-pass" approach using US first and then CT if US is not diagnostic may be desirable in some institutions.

Dyspnea and chest pain are common presenting complaints to the ED, and coupled together can present a challenging diagnostic dilemma in patients in extremis. A thoughtful evaluation is required, giving due diligence to the immediate life threats as well as multiple etiologies which can cause serious morbidity. A perforated peptic ulcer is one such possibility and requires rapid diagnosis and prompt intervention to avoid the associated high risk of morbidity and mortality. ⋯ Perforated ulcers can have highly varied presentations and are occasionally difficult to diagnose in a complicated patient. Knowledge of the risk factors and a thorough history and physical can point to the diagnosis, but timely and appropriate imaging is often required because delays in diagnosis and treatment lead to poor outcomes. Early administration of antibiotics and immediate surgical repair are necessary to limit morbidity and mortality.

In the care of patients with traumatic injuries, focus is placed on hypothermia secondary to its deleterious impact on the coagulation cascade. However, there is scant information on the mortality effect of hyperthermia. ⋯ Care of the victim with traumatic injuries emphasizes avoidance of hypothermia; however, hyperthermia is also detrimental. The presence of hypothermia or hyperthermia should be considered in the initial treatment of the patient with traumatic injuries.

The goal of this study was to identify publications in the medical literature that support the efficacy or value of Emergency Medicine (EM) as a medical specialty and of clinical care delivered by trained emergency physicians. In this study we use the term "value" to refer both to the "efficacy of clinical care" in terms of achieving desired patient outcomes, as well as "efficiency" in terms of effective and/or cost-effective utilization of healthcare resources in delivering emergency care. A comprehensive listing of publications describing the efficacy or value of EM has not been previously published. It is anticipated that the accumulated reference list generated by this study will serve to help promote awareness of the value of EM as a medical specialty, and acceptance and development of the specialty of EM in countries where EM is new or not yet fully established. ⋯ There is extensive medical literature that supports the efficacy and value for both EM as a medical specialty and for emergency patient care delivered by trained EM physicians.
