Randomized Controlled Trial Multicenter Study Clinical Trial
Safety and efficacy of flumazenil in reversing conscious sedation in the emergency department. Emergency Medicine Conscious Sedation Study Group.
To evaluate the safety and efficacy of flumazenil vs placebo in reversing fentanyl and midazolam-induced conscious sedation in ED patients undergoing a short, painful procedure. ⋯ Flumazenil is safe and efficacious in reversing midazolam-induced sedation in ED patients given a combination of fentanyl and midazolam to facilitate the performance of a short, painful procedure. The patients given flumazenil returned to baseline alertness earlier and at a faster rate than did the patients given placebo. However, flumazenil did not alter the actual interval from procedure completion until ED release.

Rotating shiftwork schedules: can we enhance physician adaptation to night shifts?
To evaluate the effectiveness of a broad, literature-based night shiftwork intervention for enhancement of emergency physicians' (EPs') adaptation to night rotations. ⋯ Although the experimental intervention was successfully implemented, it failed to significantly improve attending physicians' sleep, performance, or mood on night shifts. A decrease in speed of intubation, vigilance reaction times, and subjective alertness was evident each time the physicians rotated through the night shift. These findings plus the limited sleep across all conditions and shifts suggest that circadian-mediated disruptions of waking neurobehavioral functions and sleep deprivation are problems in EPs.

There is a rapidly growing interest in emergency medicine (EM) and emergency out-of-hospital care throughout the world. In most countries, the specialty of EM is either nonexistent or in an early stage of development. Many countries have recognized the need for, and value of, establishing a quality emergency health care system and are striving to create the specialty. ⋯ Since the United States has an advanced emergency health care system and the longest history of recognizing EM as a distinct medical specialty, lessons learned in the United States may benefit other countries. In order to provide appropriate advice to countries in the early phase of emergency health care development, careful assessment of national resources, governmental structure, population demographics, culture, and health care needs is necessary. This paper lists specific recommendations for EM organizations and physicians seeking to assist the development of the specialty of EM internationally.

Comparative Study
Underrecognition of cervical Neisseria gonorrhoeae and Chlamydia trachomatis infections in the emergency department.
1) To quantify the frequency of underrecognized Neisseria gonorrhoeae and Chlamydia trachomatis cervical infections in women tested in the ED, 2) to describe and compare the characteristics of those treated and not treated during the initial visit, and 3) to quantify the delay interval until treatment was provided. ⋯ In this population, both N. gonorrhoeae and C. trachomatis cervical infections are frequently underrecognized in the ED, with isolated C. trachomatis infections associated with significantly higher proportions of underrecognition. Many affected women remain untreated for extended intervals, creating public and individual health risks. Improved point of contact detection, follow-up, and treatment policies are needed to limit these risks.

To determine whether the absence of a gestational sac on transvaginal ultrasonography in patients with a quantitative beta-human chorionic gonadotropin (beta-hCG) > 3,000 mIU/mL and/or menstrual days > 38 excludes the diagnosis of a normal intrauterine pregnancy (IUP). ⋯ In patients with either a beta-hCG > 3,000 mIU/mL or menstrual days > 38 and no gestational sac by transvaginal ultrasonography, the likelihood of a normal IUP is low.
