|Text||Bacterial tracheitis (Membranous laryngotracheobronchitis). This disease is a rare but more severe form of croup. It is a superinfection of a preceding viral upper respiratory infection. It is typically seen in children younger than 3 years, but it can be seen in patients ages 3 months to 13 years. Usually caused by S. aureus, S. pneumonia, H. influenza, and M. catarrhalis.
Patients with bacterial tracheobronchitis have more respiratory distress than do patients with croup. Children appear septic and present similarly to those with epiglottitis.
Radiographs of the lateral neck and chest usually reveal subglottic narrowing of the trachea. Irregular densities can be seen within the trachea and its borders may appear ragged and indistinct.
Management is similar to that of epiglottitis with more than 85% of these patients requiring intubation. Ideally they should go to the OR for intubation and bronchoscopy.
Empiric antibiotics require vancomycin 10mg/kg IV every 6 hrs and a third generation cephalosporin, such as, ceftriaxone 50 mg/kg IV per dose.
With prompt treatment of this disease, patients recover well. Complications of delayed diagnosis include respiratory failure due to obstruction, and septic shock.
