Strategies for diagnosing ectopic pregnancy that defer endovaginal ultrasound in women with suggestive symptoms and serum beta-human chorionic gonadotropin (beta-hCG) levels less than 1500 mIU/mL ignore the increased risk of ectopic pregnancy in these patients. ⋯ In women with pain or bleeding and serum beta-hCG levels less than 1500 mIU/mL, the risk of ectopic pregnancy is substantially increased, while the likelihood of normal intrauterine pregnancy is low.

Comparative Study
Predictors of success in emergency medicine ultrasound education.
To compare emergency medicine resident performance on an ultrasound-oriented, American Board of Emergency Medicine-styled written examination with the following variables in resident education: number of ultrasound scans performed, presence of a formal, structured ultrasound rotation, presence of a mandatory ultrasound rotation, number of hours of didactic ultrasound education, and percentage of ultrasound education taught by emergency physicians. ⋯ Improved resident performance on an ultrasound written examination was associated with increasing resident year, number of scans performed, and the presence of an ultrasound rotation at the residency program. Increasing the number of didactic hours spent on ultrasound each year beyond 15 hours showed no improvement in resident performance.

It is unclear whether ketamine induces subclinical respiratory depression when administered in dissociative doses intravenously (IV). The authors report a pilot study of capnography in emergency department (ED) pediatric patients receiving ketamine alone for procedural sedation, and describe serial measures of ventilatory response [end-tidal carbon dioxide (EtCO(2)), respiratory rate, pulse oximetry]. ⋯ No hypoventilation was observed in 20 ED pediatric patients receiving ketamine 1.5 mg/kg administered IV over 1 minute. The authors found no evidence of respiratory depressant properties for this dissociative agent.

Emergency department (ED) overcrowding is a common problem. Despite a widespread belief that low hospital bed availability contributes to ED overcrowding, there are few data demonstrating this effect. ⋯ Increased hospital occupancy is strongly associated with ED length of stay for admitted patients. Increasing hospital bed availability might reduce ED overcrowding.

Review
Tissue adhesives for traumatic lacerations: a systematic review of randomized controlled trials.
To summarize the best available evidence for the effect of tissue adhesives (TAs) in managing traumatic lacerations in children and adults. ⋯ TAs are an acceptable alternative to SWC for simple traumatic lacerations. No difference in cosmesis was found between TAs and SWC, or between different TAs. Tissue adhesives offer the benefits of decreased procedure time and less pain, compared with SWC. A small increased rate of dehiscence with TAs must be considered when choosing the closure method (NNH = 25).
