Randomized Controlled Trial Comparative Study Clinical Trial
Humidification in viral croup: a controlled trial.
Sixteen children (mean age 1.9 years) admitted to hospital with viral croup were assigned randomly to either a high humidity atmosphere or room air. No other treatment was given. ⋯ No therapeutic benefit was demonstrated from the provision of a high humidity atmosphere. The widespread use of humidification in the management of croup requires reappraisal.
