探讨肺功能检测在小儿哮喘和咳嗽变异性哮喘中的价值

Exploration on the Value of Lung Function Testing in Children with Asthma and Cough Variant Asthma

目的分析在小儿哮喘和咳嗽变异性哮喘中行肺功能检测的实际价值。方法对该院在2018年1月—2019年7月收治的90例小儿哮喘和咳嗽变异性哮喘患儿,将其看作为研究组,同时在选择同期70名健康小儿,将其看作为对比组。所有研究对象均进行肺功能检测和常规检查,分析两组研究对象最终肺功能检测结果,对比肺功能检测与常规检查的差异性。结果研究组处于急性发作期患儿肺功各项指标与对比组小儿肺功各项指标对比,差异有统计学意义(t=55.034、17.626、14.819、39.692、12.404、28.322,P<0.05);研究组处于慢性持续期患儿肺功各项指标与对比组小儿肺功各项指标对比,差异有统计学意义(t=15.209、6.217、2.786、3.904、8.356、11.429,P<0.05);研究组处于临床缓解期患儿肺功各项指标与对比组小儿肺功各项指标对比,差异无统计学意义(t=0.321、0.095、0.065、0.159、0.901、0.431,P>0.05);肺功能检测哮喘误诊率3.64%和咳嗽变异性哮喘误诊率5.71%低于常规检查哮喘误诊率16.36%和咳嗽变异性哮喘误诊率28.57%,差异有统计学意义(P<0.05);肺功能检测哮喘确诊率96.36%和咳嗽变异性哮喘确诊率94.29%高于常规检查哮喘确诊率83.64%和咳嗽变异性哮喘确诊率71.43%,差异有统计学意义(χ^(2)=4.949、6.437,P<0.05)。结论在小儿哮喘和咳嗽变异性哮喘中行肺功能检测对于临床疾病诊断有着极大作用,有着较高的临床诊断率。

Objective To analyze the actual value of lung function testing in children with asthma and cough variant asthma.Methods 90 children with asthma and cough variant asthma admitted in the hospital from January 2018 to July 2019 were regarded as the study group,and 70 healthy children during the same period were selected as the comparison group.All subjects underwent pulmonary function tests and routine examinations.The final pulmonary function test results of the two groups of subjects were analyzed,and the differences between pulmonary function tests and routine examinations were compared.Results The lung function indexes of the children in the study group were compared with those in the comparison group,the difference was statistically significant(t=55.034,17.626,14.819,39.692,12.404,28.322,P<0.05).Comparison of lung function indexes of children in the study group in the chronic persistent period with those of the comparison group,the difference was statistically significant(t=15.209,6.217,2.786,3.904,8.356,11.429,P<0.05).Comparison of lung function indexes of children in the study group in clinical remission with those of the comparison group,the difference was not statistically significant(t=0.321,0.095,0.065,0.159,0.901,0.431,P>0.05);the misdiagnosis rate of asthma by pulmonary function test was 3.64% and the misdiagnosis rate of cough variant asthma was 5.71%,which was lower than the routine check-up asthma misdiagnosis rate of 16.36% and cough variant asthma misdiagnosis rate of 28.57%.The difference was statistically significant(P<0.05).At the same time,the lung function test has a 96.36% diagnosis rate of asthma and a 94.29% diagnosis rate of cough variant asthma,which was higher than the routine examination of 83.64% and 71.43% of the diagnosis rate of cough variant asthma.The difference was statistically significant(χ^(2)=4.949,6.437,P<0.05).Conclusion Pulmonary function testing in children with asthma and cough variant asthma has a great effect on the diagnosis of clinical diseases,and has a high clinical diagnosis rate.
