Laryngotracheobronchitis (LTB) is characterized by edema and inflammation of the mucous membranes lining the larynx, trachea, and bronchi. This can cause narrowing of the airway and lead to respiratory distress. Airway smooth muscle contraction can occur as a secondary response to the inflammation, but edema is the primary anatomic alteration. Excessive alveolar fluid would be indicative of acute respiratory distress syndrome (ARDS), which is not typically associated with LTB. Epiglottitis is a separate condition that involves inflammation of the epiglottis and is not typically seen with LTB.
