A 12-year-old with sudden respiratory distress and inspiratory stridor is MOST suspicious for which condition?

• A. Croup
• B. Viral pharyngitis
• C. Anaphylaxis
• D. Bacterial epiglottitis

Answer: (D)

Sudden upper airway obstruction in a child often presents with inspiratory stridor, signaling that the airway above the vocal cords is acutely compromised. Among these conditions, bacterial epiglottitis is the most concerning cause when the presentation is abrupt with significant respiratory distress. The swollen epiglottis narrows the airway quickly, leading to prominent stridor and a toxic appearance. While epiglottitis has become less common due to vaccination, it remains a medical emergency that can deteriorate rapidly, so recognizing this pattern is crucial. Croup, by contrast, usually follows a viral URI and features a barking cough, hoarseness, and stridor that tends to develop more gradually and is often milder, especially during the day. Viral pharyngitis causes throat pain and fever without the characteristic airway obstruction signs like inspiratory stridor. Anaphylaxis can cause airway swelling and stridor too, but it typically comes with a clear allergen exposure history and systemic signs such as hives, vomiting, or hypotension, rather than a sudden, isolated airway emergency in an otherwise healthy child. So the sudden respiratory distress with inspiratory stridor in this age is most consistent with epiglottitis, a condition that demands immediate attention to secure the airway and prevent obstruction.
