Nebulised 3% Hypertonic Saline in Infants With Acute Bronchiolitis

Bronchiolitis is the most prevalent disease in infants, especially children younger than two years old. Clinical manifestations vary from mild to severe, even life-threatening respiratory failure. Airway oedema and mucus plugging are the principal pathological features in infants with acute bronchiolitis. Nebulising 3% hypertonic saline solution may reduce these pathological changes, but the evidence remains equivocal.
