Abstract:

Bronchiolitis is a common lower respiratory tract infection in infants and young children, mostly caused by respiratory syncytial virus. At present, the treatment mainly includes oxygen therapy, control of wheezing, maintenance of internal environment stability and so on. Most cases of bronchiolitis still lack specific antimicrobial agents. To explore a new treatment method for bronchiolitis is helpful to improve the symptoms, shorten hospitalization days，and improve the prognosis of children with moderate to severe bronchiolitis, especially those younger than 6 months with high risk factors.

Key words: bronchiolitis, respiratory syncytial virus infection, treatment

摘要：

毛细支气管炎是婴幼儿较常见的下呼吸道感染，多由呼吸道合胞病毒引起。目前的治疗主要为包括氧疗、控制喘息、维持内环境稳定等的综合治疗。多数毛细支气管炎尚缺乏特异性的病原治疗药物。探讨毛细支气管炎治疗新方法有助于改善患儿症状、缩短住院日，改善中重度毛细支气管炎患儿、尤其是＜6月龄且有高危因素的患儿预后。
