A meconium aspirator is a simple plastic adapter that allows for rapid suctioning of the trachea when attached to an endotracheal tube and a source of continuous negative pressure, as was historically done for suspected neonatal meconium aspiration. Adaptation of this technique for the emergent vacuum extraction of an obstructing tracheal foreign body in an adult has not been previously described. ⋯ We report the case of a 33-year-old woman with cardiorespiratory arrest after choking on food. Complete tracheal obstruction precluding oxygenation and ventilation due to aspirated chicken was diagnosed by emergency physicians and managed immediately with vacuum extraction using the technique described in this report. No additional airway interventions were necessary and the patient made a full neurologic recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Vacuum extraction using a meconium aspirator and modified endotracheal tube is a novel and potentially life-saving approach to the emergency management of airway obstruction after choking, especially if the foreign material is below the vocal cords and not amenable to manual extraction with a Magill forceps.

Appendicitis is a common pediatric surgical emergency, and the diagnosis may be delayed or missed because of nonspecific findings in children. Not all patients with abdominal pain need to be imaged for appendicitis, and laboratory evaluation may improve diagnostic accuracy in this population. ⋯ No laboratory test studied has adequate characteristics to be used alone. CRP adds minimal sensitivity beyond WBC and ANC when symptoms are >1 day but with poor specificity, making it of limited utility.

Case Reports
Point-of-Care Ultrasound Assists Diagnosis of Spontaneously Passed Common Bile Duct Stone.
Choledocholithiasis complicates approximately 10% of gallstone disease. Spontaneous stone migration out of the common bile duct (CBD) may occur in as many as 20% of choledocholithiasis cases. A decrease in CBD caliber occurs in the setting of spontaneous stone passage, but to our knowledge, this finding has not been appreciated using point-of-care ultrasound (POCUS) in the emergency medicine setting. ⋯ A 49-year-old woman presented to our Emergency Department (ED) with a complaint of epigastric pain radiating to the left shoulder. On examination she was found to have epigastric tenderness to palpation, but no guarding or rebound. POCUS demonstrated a dilated common bile duct, and her liver function tests were abnormally high. She was admitted to Medicine with concern for choledocholithiasis and plan for endoscopic retrograde cholangiopancreatography (ERCP), but her pain had resolved shortly after ED arrival. A repeat ultrasound examination demonstrated a normal-caliber common bile duct approximately 3 h after the initial scan. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Choledocholithiasis often requires admission and invasive testing. Using POCUS in conjunction with liver function tests and patient assessments may obviate a need for ERCP.

Case Reports
Mass Casualty Management After a Boiling Liquid Expanding Vapor Explosion in an Urban Area.
The catastrophic fail of a container holding a pressure-liquified gas can generate a boiling liquid expanding vapor explosion (BLEVE) with a subsequent blast wave, flying fragments, and fire or toxic gas release. ⋯ This report describes the management of a mass casualty disaster related to a BLEVE in an urban area due to a highway accident involving a tanker carrying liquified petroleum gas and a truck transporting chemical solvents. The event resulted in 158 casualties that were triaged, stabilized, and transported into the "hub" and "spoke" hospitals of the regional trauma network within 3 h and 22 min from the event by the Emergency Medical Services. The logistic complications related to the partial collapse of the highway bridge on an underlying urban road and the relative solutions adopted, as well as the application and advantages of the use of the Simple Triage and Rapid Treatment (START) algorithm in the field and the criteria adopted for the distribution of patients within the trauma network, are discussed, along with the potential pitfalls observed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: BLEVE events are rare but can be complex in both logistical management and clinical presentation of the lesions related to the event. The START algorithm is a valuable tool for rapid triage in mass casualty incidents.
