If an infant or small child swallowed a rigid foreign body, he or she would MOST likely experience respiratory distress because:

• A. It causes airway edema
• B. It enters the bronchus
• C. It causes laryngospasm
• D. The esophageal foreign body can compress the relatively pliable trachea

Answer: (D)

In children, the trachea is relatively pliable and lies just in front of the esophagus. When a rigid object becomes stuck in the esophagus, it can press forward on the trachea, narrowing the airway and triggering respiratory distress. This external compression is especially likely in infants and small kids because their airways are small and more compliant, so even a bulky esophageal object can cause noticeable breathing difficulty. Edema of the airway would require irritation or injury inside the airway itself, which isn’t the typical result of a swallowed rigid object. If the object had entered the bronchus, you’d expect signs of aspiration and focal respiratory findings rather than diffuse distress. Laryngospasm would stem from a problem at the larynx or upper airway, not from an esophageal impaction. Thus, the mechanism of external tracheal compression by an esophageal foreign body best explains the respiratory distress.
