title: [The time variations in pulmonary functional parameters in children with bronchial asthma].
abstract: 28 children with bronchial asthma, between 6 and 18 years old, were followed by a varied period of time - 3 months - 5 years. 7-8 functional tests were carried out. The cases were studied in different clinical phases: asymptomatic, manifest, crisis of bronchial asthma. The functional pulmonary investigation included: spirographic examination [vital capacity (VC), maximum expiratory volume per second (MEVS) the VC/MEVS ratio], plethysmographic examination (VGT, Raw), measurement of the maximum instantaneous expiratory flows on the flux-volume curve (MEF50). The average value, standard residual deviation and the variation coefficient were calculated for each parameter studied in different clinical moments. The results are presented on 3 groups: per total, symptomatic and asymptomatic. The analysis of the data found showed that the variation of the parameters measured during repeated functional examinations in children with bronchial asthma ranges within broad limits (2.9%-11.5%); the broadest variation was recorded for Raw followed by MEF50 and the slightest variation was that of the VC/MEVS ratio. This indicated the lower value of the information furnished by this ratio in children, in appreciating the presence or severeness degree of the obstructive syndrome.
