Randomized Controlled Trial Clinical Trial
Magnesium sulfate versus placebo for paroxysmal atrial fibrillation: a randomized clinical trial.
The objective was to investigate the efficacy of magnesium sulfate (MgSO4) in decreasing the ventricular rate in emergency department (ED) patients presenting with new-onset, rapid atrial fibrillation (AF). ⋯ This study was unable to demonstrate a difference between IV MgSO4 10 mmol and saline placebo for reducing heart rate or conversion to sinus rhythm at 2 hours posttreatment in ED patients with AF of less than 48 hours duration.

Aneurysmal subarachnoid hemorrhage (SAH) is a devastating disorder that still requires much clinical study. However, the decision to participate in a randomized clinical trial, particularly a neuroemergency trial, is a complex one. The purposes of this survey were to determine who would participate in a randomized clinical trial that intended to examine transfusion practices after SAH, to identify who could serve as potential proxy decision-makers, and to find which patient characteristics were associated with the decision to participate. ⋯ Greater than half of respondents stated they would participate in a proposed emergency treatment trial for SAH. Our survey suggests that the decision to participate is highly individualized, because no demographic, pathologic, historical, or access-related predictors of choice were found. Educational materials designed for this type of trial would need to be broad-based. Family members should be considered as proxy decision-makers where permitted by federal and local regulations.

Multicenter Study
Predictors of hospital admission for chronic obstructive pulmonary disease exacerbations in Canadian emergency departments.
The objective was to examine predictors of hospital admission among adults presenting to Canadian emergency departments (EDs) for acute exacerbations of chronic obstructive pulmonary disease (COPD). Current acute treatment approaches and outcomes 2 weeks after the ED visit are also described. ⋯ Exacerbations of COPD in Canadian EDs result in prolonged ED stays and approximately 50% hospitalization despite aggressive acute treatment approaches. Historical, severity, and treatment-related factors were strongly associated with hospital admission. Validation of these results should be completed prior to widespread use.
