[Modern approach to the therapy of viral croup].

Viral croup as the most frequent of laryngeal obstructions in childhood appears in the form of spasmodic croup and acute laryngotracheitis. The evaluation of the severity of laryngeal obstruction can be made by using score systems. In more severe forms of viral croup the inhalation of 0.25 ml/kg 2.25% epinehrine and a single dose dexamethasone 0.6 mg/kg i.m. is recommended.
