目的分析哮喘和咳嗽变异性哮喘儿童肺通气功能检测的临床价值。方法 80例哮喘或咳嗽变异性哮喘患儿作为实验组,40例正常儿童作为对照组。比较两组儿童的肺通气功能指标,分析肺通气功能检测前后的实验组患儿的确诊率及误诊率,评估其临床应用价值。结果实验组患儿病情稳定期肺功能指标与对照组比较差异无统计学意义(P>0.05);实验组患儿病情进展期及急性发作时肺功能各指标与对照组比较差异具有统计学意义(P<0.05)。肺通气功能检测方法确诊率高于常规听诊与问诊检测法,差异具有统计学意义(P<0.05)。结论临床上通过监测哮喘与咳嗽变异性哮喘患儿不同病情进展时期的肺通气功能指标变化,具有较高的临床确诊率,值得广泛推广使用。
Objective To analyze the clinical value of detecting pulmonary ventilation in children with asthma and cough variant asthma. Methods Eighty children with asthma or cough variant asthma were selected as experimental group and 40 normal children as control group. The indexes of pulmonary ventilation were compared between the two groups. The diagnostic rate and misdiagnosis rate of the experimental group before and after the pulmonary ventilation test were analyzed, and its clinical value was evaluated. Results There was no significant difference in the indexes of pulmonary function between the experimental group and the control group (P> 0.05). There was significant difference between the experimental group and the control group in the progression of the disease and acute attack (P <0.05). The diagnostic rate of pulmonary function test was higher than that of routine auscultation and interrogation test, the difference was statistically significant (P <0.05). Conclusion Clinical monitoring of asthma and cough variant asthma in children with different stages of disease progression of pulmonary ventilation index changes, with a high clinical diagnosis rate, it is widely used.
