We have investigated the relationship of clinical variables to successful cardioversion of atrial fibrillation (AF) to sinus rhythm using an oral loading dose of propafenone. Fifty consecutive patients with recent onset (< 72 hours) atrial fibrillation of various aetiologies were included in the study cohort. All patients were given the study medication while in the emergency department and then monitored for 8 hours. ⋯ We investigated the effect of clinical factors such as age, sex, presence of hypertension (HT), chronic obstructive lung disease (COPD), diabetes mellitus (DM), mitral stenosis (MS), congestive heart failure (CHF), coronary artery disease (CAD) and the duration of atrial fibrillation on conversion to sinus rhythm. Of these factors, univariate and multivariate analysis showed that only the duration of atrial fibrillation was a significant predictor of conversion (p = 0.002). Our results suggest that most patients with new-onset AF can be converted successfully to sinus rhythm with a low incidence of adverse reactions using oral propafenone in the emergency department.

The purpose of this study was to evaluate prehospital sedation protocols used by several French mobile intensive care units for difficult intubations in poisoned patients. This prospective, descriptive study was performed within the toxicological intensive care unit in a university hospital. Consecutive poisoned patients intubated during their airway management by prehospital medical teams were included. ⋯ The use of etomidate alone as an intubation sedative agent was associated with significantly poorer intubating conditions (47.2% difficult) than other sedative agents or neuromuscular blockade). Neuromuscular blockade with sedation in our series was associated with the lowest incidence of difficult intubations in poisoned patients. Sedation alone for intubation appears to be inadequate to achieve good intubating conditions in a significant proportion of patients.
