Angioedema is a complication that has been reported in up to 1.0% of individuals taking angiotensin-converting enzyme inhibitors (ACE-Is). Importantly, the onset of angioedema can occur anywhere from hours to several years after initiation of therapy with ACE-Is. Although most cases of ACE-I-induced angioedema (ACE-I-AE) are self-limiting, a major clinical concern is development of airway compromise, which can potentially require emergent airway management. The underlying pathophysiology of ACE-I-AE is incompletely understood, but is considered to be due in large part to excess bradykinin. Numerous medications have been proposed for the treatment of ACE-I-AE. This article is an update to the 2011 Clinical Practice Committee (CPC) statement from the American Academy of Emergency Medicine. ⋯ The primary focus for the treatment of ACE-I-AE is airway management. In the absence of high-quality evidence, no specific medication therapy is recommended for its treatment. If, however, the treating physician feels the patient's presentation is more typical of an acute allergic reaction or anaphylaxis, it may be appropriate to treat for those conditions. Any patient with suspected ACE-I-AE should immediately discontinue that medication.

Pit vipers, also known as crotalids, are a group of snakes including rattlesnakes, copperheads, and cottonmouths (water moccasins). Crotalids have a broad geographic distribution across the United States, and bites from these snakes can carry significant morbidity. Their envenomations are characterized by local tissue effects, hematologic effects, and systemic effects. Envenomations are generally treated with 1 of 2 antivenoms available in the United States. ⋯ Patients should be initially evaluated, stabilized, and assessed for local effects, hematologic effects, and systemic toxicity suggestive of envenomation. Antivenom should be given if toxic effects are present. Surgical intervention including debridement and fasciotomy should be avoided. Prophylactic antibiotics are not necessary.

Patients presenting to the emergency department with a possible barbeque brush bristle ingestion pose many challenges. A detailed history and oral examination is needed and the typical first line investigation involves flexible laryngoscopy for direct visualization of the bristle. ⋯ Why Should an Emergency Physician Be Aware of This? Emergency physicians should have a high index of suspicion for bristle ingestion in patients with acute onset of pain or a foreign body sensation after ingesting grilled meats. Patients may require imaging to identify bristles if physical examination and laryngoscopy is negative.

Rapidly assessing an undifferentiated patient and developing a gestalt for "sick vs. not sick" is a core component of emergency medicine (EM). Developing this skill requires clinical experience and pattern recognition, which can be difficult to attain during a typical EM clerkship. ⋯ A teaching shift in triage can increase medical students' self-assessed rapid assessment skills for patients in the ED. Benefits to the teaching attending included the opportunity to perform direct observation, give real-time feedback, and identify real-time teaching moments.

Several studies reported that the National Early Warning Score (NEWS) has shown superiority over other screening tools in discriminating emergency department (ED) patients who are likely to progress to septic shock. ⋯ The discrimination power of the model for screening septic shock using NEWS, age, gender, and the six vital signs collected at ED triage outperformed the baseline NEWS model.
