目的:研究治疗婴幼儿毛细支气管炎的有效疗法。方法:采用重组人干扰素α2b注射液雾化吸入联合静脉应用喜炎平注射液治疗60例小儿毛细支气管炎,同时与60例对照组患儿进行疗效对比。结果:治疗组患儿的治愈率为93.3%,对照组患儿的治愈率为66.6%(χ2=13.3,P<0.05);治疗组临床主要症状好转以及住院时间较对照组明显缩短(P<0.05)。结论:干扰素雾化吸入联合喜炎平注射液治疗小儿毛细支气管炎疗效确切,值得推广。 Objective: To study the effective treatment of infantile bronchiolitis. Methods: Sixty children with bronchiolitis were treated with inhalation of recombinant human interferon α2b injection combined with Xiyanping injection, and the therapeutic effect was compared with that of 60 children with control group. Results: The cure rate was 93.3% in the treatment group and 66.6% in the control group (χ2 = 13.3, P <0.05). The main clinical symptoms and hospital stay in the treatment group were significantly shorter than those in the control group (P < 0.05). Conclusion: Interferon atomization inhalation combined with Xiyanping injection for the treatment of pediatric bronchiolitis is effective and worthy of promotion.
