Atrial fibrillation (AF) is the most common arrhythmia seen in patients presenting to the emergency department (ED). Pharmacological conversion of atrial fibrillation to normal sinus rhythm (NSR) may be a feasible management strategy in selected patients. Recent guidelines have recommended intravenous amiodarone, a class III antiarrhythmic agent, for the conversion of AF to NSR. ⋯ High dose IV or combined IV and oral administration may be effective as early as 8 hours in patients with recent-onset AF of <48 hour duration in patients without contraindications to these high dose regimens. There are no data to support the use of IV amiodarone for acute conversion in patients with an ejection fraction of <40% or clinical heart failure, so its use in these scenarios should be limited to symptomatic patients who are refractory to electrical conversion. More well-designed studies are required to determine the role of IV amiodarone for the acute conversion of AF in the ED.

This study evaluated the incidence of subarachnoid hemorrhage (SAH) and the use of computed tomography (CT) and lumbar puncture (LP) in a cohort of emergency department (ED) patients with acute headache. ⋯ Diagnostic testing was associated with substantially prolonged lengths of stay. CT and LP had low diagnostic yields, which suggests the need for a clinical decision rule to rule out SAH in ED patients with acute headache.

Cardiac marker sensitivity depends on chest pain duration at the time of sampling. Our objective was to estimate the sensitivity, specificity, and likelihood ratios of early CK-MB and myoglobin assays in patients presenting to the emergency department (ED) with nondiagnostic ECGs, stratified by the duration of ongoing chest pain at the time of ED assessment. ⋯ Regardless of chest pain duration, single assays and early serial markers (0+1 hr) do not rule out AMI; therefore, serial assays over longer observation periods are required. Likelihood ratios derived in this study will help physicians who use Bayesian analysis to determine post-test AMI likelihood in patients with chest pain.

The underuse of analgesics, or "oligoanalgesia," is common in emergency departments (EDs). To improve care we must understand our patients' pain experiences as well as our clinical practice patterns. To this end, we examined pain etiology, pain management practices and patient satisfaction in 2 urban EDs. ⋯ In the 2 EDs studied, we found high levels of pain severity for our patients, as well as low levels of analgesic use. When used, analgesic administration was often delayed. Despite these findings, patient satisfaction remained high. Despite recent efforts to improve pain management practice; oligoanalgesia remains a problem for our specialty.

Research has demonstrated that experienced emergency physicians can identify a subgroup of patients with shoulder dislocation for whom pre-reduction radiographs do not alter patient management. Based on that research, a treatment guideline for the selective elimination of pre-reduction radiographs in clinically evident cases of anterior shoulder dislocation was developed and implemented. The primary objective of this study was to prospectively determine whether the treatment guideline safely eliminates unnecessary radiographs. ⋯ Experienced emergency physicians are frequently certain of the diagnosis of anterior shoulder dislocation on clinical grounds alone and can comfortably and safely use this guideline for the selective elimination of pre-reduction radiographs. Compliance with the guideline substantially decreases pre-reduction radiographs. Validation of the guideline in other settings is warranted.
