We describe, in comparison with a control group, frequent attenders to an emergency department in terms of their general health service use and their clinical, psychological, and social profiles. ⋯ Frequent attenders to the ED are also heavy users of general practice services, other primary care services, and other hospital services. General Medical Services-eligible patients (84% of frequent attenders) frequently attend the ED, even though they have free access to primary care. Frequent attenders are a psychosocially vulnerable group, and service providers and policy makers need to take account of this vulnerable patient profile as they endeavor to meet their service needs.

The publication of comprehensive evidence-based guidelines for the management of non-ST-segment elevation acute coronary syndrome by the American College of Cardiology and the American Heart Association in September 2000 marked a sentinel event in the evolution of managing this challenging patient population. Many of the recommendations included in the guidelines have relevance to the emergency department care of patients with non-ST-segment elevation acute coronary syndrome and were summarized in Annals of Emergency Medicine in September 2001. ⋯ Several of the modified and new recommendations again potentially affect ED management. These are presented and discussed here.

Crotalidae Polyvalent Immune Fab (CroFab; FabAV) antivenom prevents a decrease in perfusion pressures in intramuscular crotaline envenomation compared with normal saline solution. ⋯ FabAV limits the decrease in perfusion pressures in the anterior leg compartment after intramuscular crotaline venom injection in swine compared with saline solution. In addition, FabAV might prevent the development of coagulopathy and increase survival time in this model.

The rapid 4-step technique for cricothyrotomy was originally described as making use of a single traction hook on the cricoid ring. However, it is possible that such hook placement could lead to damage of the cricoid ring. As an alternative, a double-hook device was developed to augment the rapid 4-step technique by dispersing forces applied to the cricoid ring. The objectives of this study were to compare the requisite forces for intubation and the structural tolerances of the cricoid ring between the single- and double-hook techniques. ⋯ When applying the rapid 4-step technique for cricothyrotomy, the force required to intubate with either the single- or double-hook technique is small. The cricoid ring, however, tolerates significantly more force without breakage when the double-hook technique is used.

The objective of this study was to determine the frequency of complications associated with the use of multiple-dose activated charcoal. ⋯ Clinically significant complications associated with the use of multiple-dose activated charcoal occur infrequently.
