laryngotracheobronchitis

Croup (or laryngotracheobronchitis) is caused by a virus and leads to swelling inside the throat.

Croup also can be laryngeal diphtheria, bacterial tracheitis, laryngotracheobronchitis, and laryngotracheobronchopneumonitis.

Commonly used in croup (laryngotracheobronchitis) and when stridor is present after removal of an endotracheal tube (extubation).

Antyllus wrote that tracheotomy was not effective however in cases of severe laryngotracheobronchitis because the pathology was distal to the operative site.

Croup (Laryngotracheobronchitis) Definition Acute upper airway illness causing subglottic obstruction.

• Croup (Laryngotracheobronchitis)

Others use the term more broadly, to include acute laryngotracheitis, spasmodic croup, laryngeal diphtheria, bacterial tracheitis, laryngotracheobronchitis, and laryngotracheobronchopneumonitis.

Corynebacterium diphtheriae causes laryngeal diphtheria; bacterial tracheitis, laryngotracheobronchitis, and laryngotracheobronchopneumonitis come from a virus infection, followed by a bacteria infection.

Laryngeal diphtheria is due to Corynebacterium diphtheriae while bacterial tracheitis, laryngotracheobronchitis, and laryngotracheobronchopneumonitis are usually due to a primary viral infection with secondary bacterial growth.
