This issue, depending on the child’s clinical symptoms and signs, needs to be treated differently. If hospitalization is necessary, it generally manifests as poor spirits and signs of laryngeal obstruction. Or, if in the outpatient hospital treatment through oral and nebulized therapies are ineffective, hospital admission may be considered, especially with careful observation for progression of laryngeal obstruction. Some children may also have persistent high fever that does not subside, possibly leading to convulsions and dehydration. After admission, close monitoring of vital signs and management of complications can be provided.
