The aim of the study was to evaluate the results of plethysmography in comparison to spirometry. A retrospective study of pulmonary function tests was performed in 50 asthmatic children, 6 to 15 years old, free of acute symptoms. Mild airway obstruction was found in 8 spirometries, while the other 42 were found within normal limits. In the plethysmography, obstruction was found in 27 cases, 23 without abnormalities in resistance or specific conductance. Eleven cases suggested pulmonary air trapping and/or hyperinflation. Airway obstruction was evident in 54% of plethysmographies. The difference between both studies was significant, also as well as the airway obstruction and intensity of the clinical disease. We therefore conclude that the plethysmography shows more alteration in their parameters than spirometry for the detection or suggestion of airway obstruction in asthmatic children during asymptomatic periods.
本研究的目的是评估体积描记法与肺量计检查结果的对比情况。对50名6至15岁无急性症状的哮喘儿童进行了肺功能测试的回顾性研究。在肺量计检查中发现8例轻度气道阻塞，其余42例在正常范围内。在体积描记法检查中，发现27例有阻塞，其中23例阻力或比导率无异常。11例提示有肺内气体潴留和/或肺过度充气。54%的体积描记法检查显示气道阻塞。两项研究之间的差异具有显著性，气道阻塞与临床疾病的严重程度之间也存在显著差异。因此，我们得出结论，对于无症状期哮喘儿童气道阻塞的检测或提示，体积描记法显示其参数变化比肺量计检查更多。
