Angioedema attacks, characterized by the transient swelling of the skin and mucosae, are a frequent cause of visits to the emergency department. Swellings of the oral cavity, tongue, or larynx can result in life-threatening airway obstruction, while abdominal attacks can cause severe pain and often lead to unnecessary surgery. The underlying pathophysiologic process resulting in increased vascular permeability and plasma extravasation is mediated by vasoactive molecules, most commonly histamine and bradykinin. ⋯ The low awareness among physicians of the existence of rare forms of angioedema with different aetiologies and pathogenesis, considerably adds to the problem. Also poorly appreciated by emergency personnel may be the recently introduced bradykinin-targeted treatments. The main objective of this consensus statement is to provide guidance for the management of acute angioedema in the emergency department, from presentation to discharge or hospital admission, with a focus on identifying patients in whom new treatments may prevent invasive intervention.

Comparative Study Observational Study
Comparison of video laryngoscopy to direct laryngoscopy for intubation of patients with difficult airway characteristics in the emergency department.
The objective of the study is to compare the efficacy of video laryngoscopy (VL) to direct laryngoscopy (DL) on the first pass intubation success of patients with difficult airway characteristics (DACs) in the emergency department (ED). Over a 6-year period, between July 1 2007 and June 30 2013, all intubations performed in an academic ED were recorded in a continuous quality improvement (CQI) database by the operators. The CQI form included information such as patient demographics, operator level of training, device(s) used, number of attempts and outcome of each attempt. ⋯ After adjusting for potential confounders, VL was associated with higher odds of first pass success for patients with no DACs (aOR 2.0, 95 % CI 1.2-3.3), one DAC (aOR 3.2, 95 % CI 1.9-5.6), two DACs (aOR 2.3, 95 % CI 1.1-4.9), and three or more DACs (aOR 2.9, 95 % CI 1.5-5.5). In patients with DACs, VL was associated with a higher first pass success than DL. VL is recommended as the primary intubating device for patients with predicted difficult airways in the ED.
