Medical history and physical exam by a doctor. Laboratory studies, such as blood counts and a throat culture. X-rays of the child's throat to determine the amount of airway obstruction. Without treatment, complete airway obstruction and death within hours. Keep the child calm and still until you reach the hospital.
Panic increases the child's breathing difficulty.
After hospitalization, use a cool-mist humidifier at night in the child's room for 2 to 3 weeks. Your doctor may prescribe antibiotics to control infection. Continue for a minimum of 10 days. See Medications section for information regarding medicines your doctor may prescribe. Activities may then be resumed gradually.
