Basics

Description

  • A tracheal infection potentially causing acute airway obstruction. Also known as bacterial croup and laryngotracheobronchitis. Exudative tracheitis can refer to a less severe form of disease
  • Usually secondary bacterial infection of trachea, complicating antecedent viral infection, or less commonly, instrumentation
  • Fatal in 0–20%
  • Tracheal membrane formation, purulent discharge, subglottic edema, erosions, with normal epiglottis
  • Classically presents with prodrome similar to croup followed by rapid deterioration and loss of airway patency
  • Mean age 5 yr; rarely occurs in adults
  • More common in children than epiglottitis, presumably due to success of Haemophilus influenzae immunization
  • More frequent August–December

ALERT
Patients may present with a fairly benign course, followed by rapid deterioration, with respiratory distress, toxic appearance, and acute airway obstruction.

Etiology

  • Staphylococcus aureus (with occ. methicillin-resistant S. aureus [MRSA])
  • Moraxella catarrhalis
  • Streptococcus pneumoniae
  • Group A streptococcal species
  • Pseudomonas aeruginosa
  • H. influenzae type B
  • Escherichia coli
  • Anaerobes
