Joint dislocations are common presenting complaints in emergency departments (EDs). Dislocations of major joints, such as the shoulder, elbow, and hip, are often difficult to gently reduce because of the challenge in obtaining sufficient relaxation of large muscle groups. ⋯ Narcotics and benzodiazepines failed to facilitate reduction at every encounter, whereas etomidate made the procedure easy the two times it was used in the ED. This article reviews the administration of etomidate for conscious sedation and discusses potential complications.

We conducted an anonymous moonlighting and academic practice survey of all emergency medicine residents enrolled in accredited programs during 1997. Expanding on previous work, this survey included specific details and practice trends of moonlighting emergency medicine residents and for comparison also included academic work requirements. The typical emergency residency program requires residents to work 204 hours monthly. ⋯ Half of all residents surveyed, whether involved in moonlighting practice or not, would violate a ban on the practice. Residents universally felt that moonlighting enhanced residency performance and was a positive educational experience. Use of these data may aid in the development of formal guidelines regarding emergency medicine moonlighting practice.

We studied the effect of low molecular weight dextran (mean molecular weight 40,000, Dextran 40; LMD) on the accumulation of extravascular lung water (EVLW), and also on hemodynamics and blood gases, in the oleic acid (OA)-injured lung in pentobarbital anesthetized rats. Starting just before the OA injection (0.01 mL/kg via femoral vein), 10% LMD in lactated Ringer's solution was infused throughout the experiment (5 mL/kg/h) instead of lactated Ringer's solution. ⋯ LMD protected against the increase in EVLW (4.14 +/- 0.10) and the hypoxemia (112 +/- 19 mmHg), but it did not reduce the albumin leakage into the alveolar space (0.052 +/- 0.009). These data suggest that LMD may limit the fluid accumulation that is secondary to OA-induced lung injury.
