Take Home Points Single dose oral dexamethasone is an excellent choice for asthma exacerbations. It takes away the compliance issue for patients who have trouble getting medications or filling medications once they leave the ED. Antibiotics aren’t always indicated in COPD exacerbations, but are used much more frequently than in asthma exacerbations because the structural changes in the patient’s lung lead to increased bacterial colonization. In general, if the patient has increased cough or sputum production, they probably would benefit from a course of antibiotics In general, azithro alone is no longer a good choice as solo covereage for community acquired pneumonia.  Adding either amoxicillin or cefdinir to you amoxicillin should get you good coverage of both strep pneumo and atypicals.

A 32 year old woman arrives in your emergency department after being in a motor vehicle collision where she was the seat-belted driver. She undergoes chest CT imaging despite a negative chest x-ray because of her ongoing anterior chest wall diffuse tenderness. You discover a small 10% pneumothorax (PTX), but no other associated thoracic injuries. Should you place a tube thoracostomy (chest tube)? Should this patient be admitted to the hospital? A 2019 Annals of Emergency Medicine paper by the NEXUS Chest research group tackles these questions.1

Background Information: In 2017, more than two-thirds of the 70,000 drug overdose deaths in the United States involved an opioid.1 Many emergency departments are affected as opioid overdoses increased 30% from July 2016 through September 2017 in 52 areas in 45 states.2 With the half-life of naloxone being between 60-90 minutes the appropriate disposition and observation time of these patients following naloxone reversal continues to be debated in the literature.3,4, A study on heroin overdose patients treated and released by pre-hospital providers showed no deaths in the one-year period studied.5 While this only applies to isolated heroin use, other studies have shown no increased incidence of death within 48 hours of patients treated with naloxone for non-fentanyl opioid overdoses.6,7 Many of these studies, however, suffer from poor follow up which is unsurprising given the difficulty in tracking patients with opiate use disorders. It is important to note that the increased presence of synthetic and long-acting opioids further complicates this topic. A systematic review of a clinical prediction rule known as the St. Paul’s Early Discharge Rule, concluded that ambulatory patients with normal vital signs, and a Glasgow Coma Scale (GCS) of 15 only needed 1 hour of observation prior to discharge.8,9 The authors of this study sought to validate this single center derived rule and its six criteria.

The Problem Emergency Medicine (EM) residents are expected to be familiar with and competent in performing a wide number of procedures, including rare ones such as performing an escharotomy in a patient with severe burns. Unfortunately, there is a paucity of readily available simulation models to facilitate practice of this rare yet potentially life-saving skill.
