To analyze the impact of repeated forced spirometry maneuvers on oscillometry parameters of healthy children.
This is a cross-sectional study with healthy children (6-12 y old) from schools in Florianopolis-SC/Brazil. Good health condition was confirmed through questionnaires, health history, and normal spirometry. Spirometry maneuvers and impulse oscillometry were conducted according to the American Thoracic Society guidelines. The school children were grouped according to the number of spirometry maneuvers performed: 1) 3 maneuvers; 2) 4 maneuvers and 3) 5 to 8 maneuvers. The following oscillometry values were considered: at rest (T); after the first spirometry maneuver (T); and after the last maneuver (T), according to the groups' allocation. The mixed model ANOVA was applied to verify the interaction of oscillometry parameters in all 3 moments and groups. The Friedman test was used for analysis of Fres (p < 0.05).
In 149 school children (mean age: 9.13 y old ± 1.98), there was a significant increase in Z5, R5, R20, and X5 values at rest and after the first spirometry maneuver, and values at rest and after the last maneuver in all groups. The effects on analyzed variables were significant in Z5 (F: 12.35; gl: 2; p < 0.001), R5 (F: 11.14; df: 2, p < 0.001), R20 (F: 7.53; df: 2, p < 0.001), and X5 (F: 4.30; df: 2, p = 0.014).
There were changes in respiratory mechanics after spirometry, like the increase in baseline Z5, R5, R20, and X5 after the first forced spirometry maneuver, and in comparison to the last maneuver obtained.
分析重复用力肺活量测定操作对健康儿童振荡法参数的影响。
这是一项针对巴西圣卡塔琳娜州弗洛里亚诺波利斯市学校中6至12岁健康儿童的横断面研究。通过问卷、健康史和正常肺活量测定确认健康状况良好。根据美国胸科学会指南进行肺活量测定操作和脉冲振荡法。学龄儿童根据进行的肺活量测定操作次数分组：1）3次操作；2）4次操作；3）5至(8)次操作。根据分组情况，考虑以下振荡法值：静息时（(T)）；第一次肺活量测定操作后（(T)）；最后一次操作后（(T)）。应用混合模型方差分析来验证所有三个时刻和组中振荡法参数的相互作用。使用Friedman检验分析Fres（(p\lt0.05)）。
在149名学龄儿童（平均年龄：(9.13)岁±(1.98)）中，静息时以及第一次肺活量测定操作后，所有组中Z5、R5、R20和X5值均显著增加，静息时和最后一次操作后的值也显著增加。对分析变量的影响在Z5（(F)：(12.35)；自由度：(2)；(p\lt0.001)）、R5（(F)：(ll.14)；自由度：(2)，(p\lt0.001)）、R20（(F)：(7.53)；自由度：(2)，(p\lt0.001)）和X5（(F)：(4.30)；自由度：(2)，(p = 0.014)）中具有显著性。
肺活量测定后呼吸力学发生了变化，如第一次用力肺活量测定操作后基线Z5、R5、R20和X5增加，与最后一次操作获得的结果相比。
