肺功能检测在小儿呼吸系统疾病诊治中的应用

The Application of Pulmonary Function Test in Diagnosis of Respiratory System Diseases in Children

目的调查肺功能检查在小儿呼吸系统诊治中的应用情况.方法收集整理2010年2月至2011年2月诊治的小儿呼吸系统疾病患儿1 260例及呼吸内科成人呼吸系统疾病患者1 360例的临床资料,统计他们接受肺功能测定的情况并将两者进行比较.结果呼吸系统疾病患儿进行肺功能测定的有143例,其中凝似哮喘患儿有64例,确珍哮喘有17人,成人有673例测定过肺功能、其中凝似哮喘365例,确诊哮喘者103例、小儿呼吸系统疾病肺功能检查测率为11.3%,哮喘病确珍率26.5%,成人呼吸系统疾病肺功能检测率为49.5%,哮喘确诊率28.2%,小儿肺功能检测率明显低于成人肺功能检测率.结论肺功能是呼吸系统疾病诊断中的重要组成部份,可客观地反映哮喘患者气道的炎症病理变化及改变程度.

Objective To investigate the applying situation of pulmonary function test in the diagnosis of respiratory system disease in children.Methods We collected the clinical data of 1260 pediatric outpatients and 1 360 adult outpatients in our hospital from February 2010 to February 2011,and investigated and compared the ratio of pulmonary function test.Results 143 pediatric outpatients received pulmonary function test,including 64 with suspected asthma and 17 with confirmed asthma;673 adult outpatients received pulmonary function test,including 365 with suspected asthma and 103 with confirmed asthma.The ratio of pulmonary function test in the pediatric outpatients was 11.3% and the ratio of final diagnosis asthma was 26.5%,while the ratio of pulmonary function test in adult outpatients was 49.5%,and the ratio of final diagnosis asthma was 28.2%.The ratio of pulmonary function test in pediatric outpatients was lower than that in adult outpatients.Conclusions Pulmonary function is an important component in diagnosis of respiratory system disease,and can objectively reflect the inflammatory degree of airway of patients with asthma.
