Resolution of sonographic B-lines as a measure of pulmonary decongestion in acute heart failure.
Objective noninvasive measures of dyspnea in patients with acute heart failure are lacking. In this review, we describe lung ultrasound as a tool to estimate the degree of pulmonary congestion in patients presenting with acute heart failure and to monitor therapeutic efficacy. ⋯ These scores provide prognostic information for short-term clinical outcomes. Lung ultrasound has the potential to measure changes in pulmonary edema during acute heart failure management and improve risk stratification.

Emergency physicians must be masters of the airway. The patient with tracheostomy can present with complications, and because of anatomy, airway and resuscitation measures can present several unique challenges. Understanding tracheostomy basics, features, and complications will assist in the emergency medicine management of these patients. ⋯ Tracheostomy patients can present unique challenges for emergency physicians. Knowledge of the basics and features of tracheostomy tubes can assist physicians in managing life-threatening complications including tube obstruction, decannulation, bleeding, stenosis, and fistula.

Spontaneous visceral artery dissection (VAD) is a rare disease that mainly occurs in the superior mesenteric artery and celiac artery. However, VAD has been detected more frequently in the past several years because of the increasing use of computed tomography (CT) for the evaluation of abdominal symptoms. A prompt diagnosis and referral to a specialist should be made, because VAD occasionally causes critical bowel ischemia. However, there is no well-established management approach. We performed a retrospective analysis to evaluate the characteristics and prognoses of patients diagnosed with VAD. ⋯ Patients with VAD often present with sudden onset abdominal pain. Most patients were managed successfully with conservative treatment. No fatal cases were observed; however, some cases were missed, even with an enhanced CT scan. It is necessary to include VAD among the differential diagnoses of acute abdominal pain. Patients with VAD should be referred to a specialist, because this disease occasionally causes critical bowel ischemia, necessitating surgical intervention.
