[Childhood croup].
Hoarseness, whooping cough and stridor are elements of a syndrome of upper airway obstruction. In childhood, acute laryngotracheobronchitis is by far the commonest cause of this syndrome. Yet, the differential diagnosis includes a number of rare and severe entities. In many cases, the traditional distinction between viral and spasmodic types is not possible. The value of humidifying therapy has not been established. In severe cases, nebulized adrenaline is of benefit but should be reserved for hospital. The effect lasts only two hours and at times a rebound effect is observed. It is now realized that some patients treated with adrenaline can safely be discharged after a two to three hours observation. There is a large body of evidence that all children arriving at the emergency department with croup should receive steroids without delay. This policy results in a much better outcome, with important reduction in hospitalizations, intensive care unit admissions and incubations. Oral dexamethasone is the drug of choice: it is as effective, easier to administer and cheaper than nebulised budesonide. In most studies, dexamethasone has been used at a dose of 0.6 mg/kg but there is some evidence that 0.15 mg/kg may be just as effective.
