Comparative Study
Hyperbaric oxygen does not prevent neurologic sequelae after carbon monoxide poisoning.
Delayed neurologic sequelae occur in up to 40% of severe carbon monoxide (CO) poisonings. Conflicting clinical data support the efficacy of hyperbaric oxygen (HBO) therapy in the acute treatment of CO poisoning. ⋯ These results suggest that HBO is not effective in preventing neurologic sequelae in mice and that there is no benefit of HBO over NBO following severe CO neurotoxicity.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized clinical trial of oral versus intramuscular delivery of steroids in acute exudative pharyngitis.
Previous study has shown that the use of intramuscular (IM) steroid leads to improved symptoms in patients with group A beta-hemolytic streptococcus (GABHS). ⋯ The results of this clinical trial suggest that oral steroid and IM steroid provide similar levels of pain relief in acute exudative pharyngitis.

The assessment of pre-procedure fasting and control of sedation depth are prominent elements of widely disseminated procedural sedation guidelines and of the Joint Commission on Accreditation of Healthcare Organizations' standards. Both exist primarily to minimize the risk of pulmonary aspiration of gastric contents. This paper critically examines the literature on pre-procedure fasting and controlling sedation depth in association with pulmonary aspiration, and interprets this evidence in the context of modern emergency medicine practice. ⋯ It is noted that aspiration during ED PSA has not been reported in the medical literature and that aspiration during general anesthesia and labor and delivery is uncommon. The literature provides no compelling evidence to support specific fasting periods for either liquids or solids prior to PSA, and existing guidelines for elective patients are of necessity arbitrary and based upon consensus opinion. The article discusses the implications in the areas of training and preparedness, monitoring, and research for the emergency physician practicing PSA.

Comparative Study Clinical Trial
Tissue harmonic imaging improves organ visualization in trauma ultrasound when compared with standard ultrasound mode.
The focused abdominal sonography for trauma (FAST) examination is complicated by brightly lit trauma bays, limited time, and body habitus. Recently, new ultrasound (US) technology has become available that improves organ visualization in abdominal scans. ⋯ Tissue harmonics produced FAST images higher in detail, resolution, and total image quality than standard-mode US images.

Medical education has adopted the use of digital photography and other computer technology, which has changed the face of the classroom. Today's presentations couple a computer and digital projection system to create powerful teaching tools. Integration of quality medical images enhances presentations in a way never before possible and at a much lower cost. ⋯ Services are available on the Internet that offer images for sale, but the cost to obtain images is high. Many institutions of higher learning provide images on the Internet for free, but the quality, number of available images, server capacity, and issues of consent limit the availability of these images. The authors describe their experience in collecting more than 20,000 clinical photographs, and provide examples of their use in emergency medicine education.
