Research suggests that hypertonic saline may improve mucous flow in infants with acute
bronchiolitis. Data suggest a trend favoring reduced length of hospital stay and improved
pulmonary scores with increasing concentration of nebulized solution to 3% and 5% saline as
compared to 0.9% saline mixed with epinephrine. To our knowledge, 7% hypertonic saline has
not been previously investigated. OUr hypothesis was that 7% hypertonic saline would improve
bronchiolitis severity scores and admission rate.
