Background: Acute asthma exacerbations are a common presentation to pediatric emergency departments (EDs). Standard treatment with inhaled beta agonists and corticosteroids are often sufficient in mild asthma but can fall short in the treatment of moderate to severe exacerbations. Magnesium sulfate (MgSO4) has long been touted as an adjunct treatment due to its bronchodilatory properties (both in its intravenous (IV) and nebulized form). Despite its routine use, the evidence for its benefit is inconsistent, particularly in the adult population where the most recent large RCT demonstrated modest benefits (Goodacre 2013).

Background: The most feared complication in the clinical course of children with diabetic ketoacidosis (DKA) is the development of cerebral edema. Cerebral edema is rare (<1%) but is the leading cause of death in pediatric DKA. Many of the details about the risk factors as well as the mechanisms leading to DKA related cerebral edema are not well understood. Before we review the recent, groundbreaking study by Kupperman et al (1), examining the relationship between intravenous fluid content and rate of fluid administration in the development of DKA related cerebral edema, it’s important that we review the associated risk factors as well as the proposed mechanisms. It is important to know that the available data we are about to review comes from retrospective studies as well as case reports and case series and not from randomized control trials.

Background: There has been lots of research published in past years on how to minimize pain and anxiety in children brought to the ED.  Unfortunately, as we all know there is often a lag time from research publication to clinical application.  It has been my experience that health care professionals tend to provide inconsistent and inadequate pain control for children.  In this episode of REBEL Cast we are going to interview Sebrina Perkins, a pediatric emergency medicine physician working for the Greater San Antonio Emergency Physicians (GSEP) group, on pediatric pain management pearls.

Background: Bronchiolitis is an acute inflammatory injury of the distal smaller airways, most commonly caused by viral infections.  There have been a host of medications studied in the treatment of bronchiolitis, including steroids, albuterol, epinephrine, and  inhaled hypertonic saline, with none proving to be effective in treatment.  Oxygen therapy via high-flow nasal cannula (HFNC) as opposed to standard nasal prongs provides some positive airway pressure which decreases work of breathing, improves oxygenation, and rates of intubation.  The trial we are going to review today (The PARIS Trial) evaluated early high-flow oxygen therapy vs standard oxygen therapy in infants with bronchiolitis and hypoxemia in both the emergency department and general pediatric ward settings.

Button Batteries: Small, disc shaped battery cells which are designed for use in small electronic devices. Common sources are kids toys, watches, calculators and hearing aids. Most batteries use lithium as a power source

Button Battery Ingestion Danger:

  • Contact with mucosal surfaces (oropharynx, esophagus, nasal passage) results in transmission of current
  • Current transmission causes chemical burns and necrosis via alkaline injury (sodium hydroxide)
  • Tissue damage can progress rapidly and result in devastating injuries
  • Nasal passage and esophagus are most susceptible to injury (narrow places for battery to become lodged)
  • Injury Patterns
    • Viscous perforation
    • Fistula formation
    • Erosion into blood vessels and resultant bleeding and possible catastrophic bleeding with erosion into aorta
