Management of bronchiolitis in children aged 1 to 23 months no longer requires testing for specific viruses or a trial dose of a bronchodilator, according to new guidelines issued by the American Academy of Pediatrics (AAP) and published online October 27 in Pediatrics.

Bronchiolitis is the most common cause of hospitalization among infants younger than 1 year. The new guideline emphasizes that only supportive care, including oxygen and hydration, is strongly recommended for young children with bronchiolitis.
