What is another name for croup?

Croup is commonly referred to as laryngotracheobronchitis due to its specific pathophysiology and the areas of the respiratory tract it affects. This condition is characterized by inflammation of the larynx (voice box), trachea (windpipe), and bronchi (the major air passages from the trachea). The inflammation leads to the classic symptoms of croup, including a barking cough, stridor, and hoarseness, which are a result of the narrowing of the airway caused by this inflammation.

This terminology helps differentiate croup from other respiratory conditions. The name "laryngotracheobronchitis" accurately describes the involvement of multiple components of the respiratory system, whereas other options provided do not capture this specific infection. Understanding this term is crucial for recognizing the clinical presentation and management of croup in pediatric patients.
