Abstract:

Bronchiolitis mainly occurs in infants under 2 years old. The infection is mainly caused by respiratory syncytial virus. Bronchiolitis  is self-limited in clinic. The treatment is mainly symptomatic and supportive treatment，including monitoring the change of disease，oxygen supply and maintaining the stability of water and electrolyte environment. Other measures should be taken to treat children with severe infection when routine oxygen inhalation，sputum aspiration and atomization are not effective. Including giving epinephrine，glucocorticoid，hypertonic saline atomization inhalation and active anti-infection treatment. More and more attention has been paid to the application of noninvasive ventilation in children with severe bronchiolitis，and early use of continuous positive airway pressure ventilation can reduce the rate of invasive tracheal intubation，effectively improve respiratory distress，reduce respiratory work and shorten hospitalization time. For children with risk factors，the changes of children’s condition should be closely monitored，and the aggravation and deterioration of the disease should be dealt with in time.
