Randomized Controlled Trial Clinical Trial
A randomized, controlled double-blind trial of usual-dose versus high-dose albuterol via continuous nebulization in patients with acute bronchospasm.
Continuous nebulization is becoming more popular in the management of acute bronchospasm in the emergency department (ED). Controversy still exists as to the optimal dose of albuterol for such exacerbations. The present study hypothesis was that there is no difference between continuous nebulization of albuterol at 7.5 mg/hr (usual dose) and 15 mg/hr (high dose) in peak flow improvement up to three hours. ⋯ In treating acute, moderately-severe bronchospastic ED patients with peak flow less than 75% of predicted with albuterol by continuous nebulization, 15 mg/hr appears to offer no advantage over 7.5 mg/hr in peak flow improvement or length of stay in the ED.

A relatively new application of emergency ultrasound is its use in the diagnosis of pneumothorax. In patients with major trauma, early detection and treatment of pneumothorax are vital. Chest radiography in these patients is limited to anteroposterior (AP) supine films, in which radiographic features of pneumothorax may be quite subtle. ⋯ Sonographic features of pneumothorax have been identified in a number of studies. The technique involves identification of the pleural line and observation for features such as "lung sliding" and comet-tail artifacts, which are absent in pneumothorax. Based on a review of the literature, the author describes these features and discusses the utility of emergency ultrasound in detecting pneumothorax.

This report summarizes recommendations on research directions developed from the conference "Alcohol Problems among Emergency Department Patients: Research on Identification and Intervention." The conference was developed in order to evaluate the existing state of the art research on emergency department interventions for alcohol problems, and offer further recommendations for research.

Previous work has suggested that low-energy biphasic waveform defibrillation (BWD) is followed by less post-resuscitation left ventricular (LV) dysfunction when compared with higher-energy monophasic waveform defibrillation (MWD). To the best of the authors' knowledge, the effect of cardiopulmonary resuscitation (CPR) duration and total ischemia time on LV function after countershock, controlling for waveform type, has not been evaluated. ⋯ Adjustment for CPR time, a determinant of total myocardial ischemia time, is necessary when defibrillation waveforms are compared for their effect on postresuscitation cardiac function and short-term outcome.

To determine the impact of emergency medicine (EM) faculty presence and an airway management protocol on success rates of tracheal intubation in the emergency department (ED). ⋯ First-attempt intubation success rates and decreased mean time to successful intubation improved following EM faculty presence and the introduction of an airway management protocol.
