Treatment: Treatment for mild croup includes cool mist, maintaining hydration, and reassurance for the child and family. In moderate to severe cases, nebulized racemic epinephrine can be administered to reduce airway swelling, and corticosteroids such as dexamethasone are given to decrease inflammation. Supplemental oxygen should be provided if hypoxemia is present, and in very rare cases, intubation may be necessary if the airway becomes critically obstructed.
