Review
An Evidence-Based Narrative Review of the Emergency Department Management of Acute Hyperkalemia.
The normal range for potassium is within narrow limits. Hyperkalemia is an electrolyte disorder that frequently affects patients in the emergency department (ED), and can result in significant morbidity and mortality if not identified and treated rapidly. ⋯ Hyperkalemia is a frequent electrolyte disorder in the ED. Because of the risk of fatal dysrhythmia due to cardiac membrane instability, hyperkalemia is a medical emergency. There is a lack of scientific evidence on the optimal management of hyperkalemia and more research is needed to establish optimal strategies to manage acute hyperkalemia in the emergency department.

Pertussis is a serious public health concern and accurate diagnosis is imperative. Comprehensive, multiplex respiratory pathogen polymerase chain reaction (PCR) panels (RPPs) have recently become popular, but their utility in excluding pertussis infection has not been fully explored. ⋯ Negative testing for B. pertussis and positive testing for other respiratory pathogens on RPP was common in samples that previously tested positive on dedicated B. pertussis PCR testing, both of which could lead to missed diagnoses of pertussis infection. Clinicians should consider using dedicated pertussis PCR testing if pertussis infection is suspected.

Observational Study
Diagnostic Accuracy of Point-Of-Care Ultrasound for Intussusception Performed by Pediatric Emergency Medicine Physicians.
Intussusception (INT) is a common cause of bowel obstruction in young children. Delay in diagnosis can lead to significant morbidity and mortality. There have been several studies evaluating early point-of-care ultrasound (POCUS) in the diagnosis of INT by nonradiologists. ⋯ POCUS performed by novice sonographers to diagnose INT has high diagnostic concordance with RPUS. Emergency department-performed POCUS is a rapid and accurate method for diagnosing INT.

There are more than 100,000 cases of esophageal foreign body in the United States each year. Most cases resolve spontaneously; however, complete esophageal obstruction is a medical emergency. Patients with developmental disabilities are at high risk, because a large percentage of this population is effected by dysphagia, pica, tooth loss, or impulsive swallowing. In some cases, the diagnosis of esophageal foreign body can be made clinically, with the typical presentation including coughing, inability to tolerate secretions, drooling, vomiting, and dysphagia. In other instances, imaging is needed to confirm the diagnosis. ⋯ A nonverbal adult patient with history of mental retardation and dysphagia presented to the emergency department (ED) after a choking episode with persistent coughing. An x-ray study of the chest showed mild opacity at the left lung base and she was discharged with antibiotics. She returned to the ED that day with worsening symptoms suggestive of aspiration pneumonia. A computed tomography scan of the chest revealed numerous cylindrical objects in the esophagus, later identified as crayons. At least 28 crayons were removed via 3 endoscopies. During this time, the patient developed aspiration pneumonia, respiratory distress, and septic shock. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Delayed recognition of foreign body puts patients at risk for esophageal perforation, aspiration, airway compromise, infection, sepsis, and death. In nonverbal patients presenting with upper respiratory symptoms, it is especially important to consider esophageal foreign body in the differential diagnosis, because this group is high risk for missed diagnosis and complications secondary to the foreign body.
