目的探讨小儿呼吸系统疾病诊治中肺功能检测的应用效果。方法将2014年1月~2015年1月我院诊治的30名患有哮喘的儿童标记为A组,另外寻找30名正常儿童标记为B组,检测A组患儿哮喘的临床缓解期、急性发作期和慢性持续期肺功能,与B组儿童肺功能进行对比。结果临床缓解期A组与B组对比不明显,而在急性发作期和慢性持续期,A组的第一秒末的呼吸容积、肺活量、最大呼吸气的峰流速明显低于B组,而残气量和残气量/肺总量明显高于B组。结论肺功能检测能间接反映哮喘病人气管炎症情况,是诊断呼吸系统疾病的重要研究手段。
Objective To investigate the effect of pulmonary function test in the diagnosis and treatment of pediatric respiratory diseases. Methods Thirty children with asthma diagnosed and treated in our hospital from January 2014 to January 2015 were enrolled as group A and 30 normal children were also enrolled as group B. The clinical remission, The onset and chronic lung function were compared with those in group B. Results There was no significant difference between group A and group B in clinical remission, but the volume of respiratory volume, vital capacity and the maximum peak velocity of respiratory gas in group A at the first second were significantly lower than those in group B at acute exacerbation and chronic phase, Volume and residual volume / total lung volume was significantly higher than the B group. Conclusion Pulmonary function tests can indirectly reflect the bronchial inflammation in asthmatic patients and is an important research tool in the diagnosis of respiratory diseases.
