摘　　要：目的:探讨单阻断法气道阻力测定在婴幼儿喘息性疾病中的临床应用价值。方法:对毛细支气管炎、婴幼儿哮喘各55例及对照组35例在吸入特布他林前后进行气道阻力测定。结果:用药前毛细支气管炎组、哮喘组气道阻力值与对照组比较,差异有高度统计学意义(P<0.01);用药后毛细支气管炎组、哮喘组气道阻力值与对照组比较,差异无统计学意义(P>0.05);毛细支气管炎组、哮喘组用药前后气道阻力值比较,差异有高度统计学意义(P<0.01)。结论:单阻断法气道阻力测定可反映婴幼儿喘息性疾病气道阻塞的状况,给临床诊断治疗提供有力的客观依据。Objective：To investigate the clinical value of airway resistance measurement using interrupter technique in infants with asthmic diseases.Methods：Airway resistance was measured before and after terbutaline inhalation in 55 infants with bronchiolitis or asthma and 35 healthy infants.Results：The value of airway resistance was higher in infants with either bronchiolitis or asthma than control subjects before inhalation,but did not differ significantly after inhalation from control subjects.The value of airway resistance on the infants of bronchiolitis and asthma differ significantly before and after inhalation.Conclusion：Measurements of airway resistance using the interrupter technique can reflect the conditions of airway obstruction and are valuable for clinical diagnosis in asthmic infants.
