OBJECTIVE: To present current concepts on diagnosis and treatment of upper airway obstruction, mainly related to differential diagnosis between acute viral laryngotracheobronchitis and epiglottitis.METHODS: Bibliographic review covering the last ten years, using both Medline system and direct research. The most relevant articles published about the subject were selected.RESULTS: Viral laryngotracheobronchitis is an acute self-limited disease of the upper airway in a child, clinically characterized by barking cough, stridor, hoarse voice, and upper respiratory symptoms. The disease is diagnosed by clinical signs and symptoms. Rarely, if no immediate airway management is needed, radiography of the neck may help to exclude other entities that cause laryngeal obstruction. In contrast to viral laryngotracheobronchitis, epiglottitis is characterized by inflammation of the supraglottic tissues and is caused mainly by Haemophilus influenzae type b. A previously healthy child suddenly develops a sore throat and fever. Within hours after the onset of symptoms the patient looks toxic, swallowing is painful and breathing is difficult. Drooling and cervical hyperextension are frequently present. Lateral neck radiograph is rarely required to the diagnosis and may delay appropriate management of the airway. Moderate viral laryngotracheobronchitis with stridor at rest and retractions should be treated with steroids (systemic or nebulized) and nebulized epinephrine. Severe viral laryngotracheobronchitis should be treated aggressively while arregements are made for endotracheal intubation. The diagnosis of epiglottitis requires immediate endotracheal intubation in the appropriate unit (emergency department, intensive care unit or surgical unit) and antimicrobial therapy. Alternatively at some medical centers children with severe upper airway obstruction have been treated with a mixture of helium and oxygen (70 to 80% concentration of helium) instead of room air or pure oxygen to avoid intubation.CONCLUSIONS: There are different levels of care for patients with upper airway obstruction, depending on their clinical presentation. The clinical manifestations of viral laryngotracheobronchitis may be confused with the presentation of epiglottitis. Despite this observation we believe that differential diagnosis between viral laryngotracheobronchitis and epiglottitis rests on clinical grounds.
