将 10 0例毛细支气管炎随机分成两组 ,对照组 5 0例采用常规疗法 ,治疗组 5 0例在采用常规疗法的基础上 ,加用干扰素 0 .5万U/kg和肝素钙 10 0U/kg微量气泵吸入 ,每日 2次 ,疗程 3～ 7天。结果治疗组治愈率 92 % ,对照组 6 4% ,两组疗效差异有高度显著性 ( χ2 =8.5 ,P <0 .0 1)。认为干扰素和肝素钙微量气泵吸入佐治毛细支气管炎疗效较好 ,无副作用 ,值得推广应用 100 cases of bronchiolitis were randomly divided into two groups, the control group of 50 patients with conventional therapy, the treatment group of 50 patients on the basis of conventional therapy, plus interferon 0.55 U / kg and heparin 10 0U / kg micro pump suction, 2 times a day, treatment of 3 to 7 days. Results The cure rate was 92% in the treatment group and 64% in the control group, with significant differences between the two groups (χ2 = 8.5, P <0.01). Interferon and heparin calcium micropump inhalation of treatment of bronchiolitis is better, no side effects, it is worth promoting
