Unfortunately, not much. Bronchiolitis is a viral infection that causes inflammation of the lower airways.
In older children and adults, the virus is nothing more than the common cold, but infants can develop wheezing and difficulty breathing. In the past, many pediatricians would try an inhaled medication in a nebulizer (such as Albuterol or Xopenex) to try and open up the airways. However, new recommendations from the American Academy of Pediatrics no longer recommend nebulizer treatments in bronchiolitis because they have not been shown to have any benefit. Your best bet should be good old nasal saline and a bulb syringe to suction your baby’s nose.
