本研究的目的是评估学龄前儿童标准肺活量评估期间用力呼气操作的可行性和可重复性。在我们实验室的 570 名幼儿中，我们回顾性地选择了 355 名首次进行肺活量测试的患者（14% 3-4 岁、48% 4-5 岁和 38% 5-6 岁）。此类测试的适应症是有哮喘病史（70%），其次是慢性咳嗽（20%）和其他杂项病症（10%）。88、175 和 92 名儿童分别进行了 1 项、2 项和 3 项可接受的测试。对于进行两次或三次尝试的儿童，1 秒用力呼气量 (FEV1) 和用力肺活量 (FVC) 没有显着差异。用力呼气时间 (FET)，即用力呼气操作所需的总时间，为 1.7 +/- 0.1 秒（平均值 +/- SEM），并且所有测试儿童中 21.3% 的时间不超过 1 秒。因此，FEV1 似乎不太适合这个年龄段。因此，在进行 3 次尝试的儿童组 (n = 92) 中测量了 0.50 秒和 0.75 秒用力呼气量 (FEV0.5、FEV0.75)，并且尝试之间没有统计学差异。在 267 名进行两项或三项测试的儿童中，再现 FEV1 和 FVC 小于或等于 0.1 L 的 ATS 标准似乎在这个年轻人群体中更可取，事实上，超过 70% 的测试儿童表现出他们的两项最大努力（FVC 和 FEV1）变化不超过 0.1 L。FEV1 和 FVC 的三项测试的个体变异系数（CV = SDI 平均值 x 100%）为 6.71 +/-分别为 0.53% 和 6.35 +/- 0.41%（平均值 +/- SEM）。这些结果表明，用力呼气测试对于幼儿来说并不总是可行，但我们选择的人群中 55% (196/355) 进行了可靠的操作（至少两次 FVC 和 FEV1 在 0.1 L 内可重复），前提是他们受到经过严格培训的儿科医务人员的监督。 (C) 2001 Wiley-Liss, Inc.
The aim of this study was to evaluate the feasibility and reproducibility of forced expiratory maneuvers during standard spirometric evaluation in preschool children. Among 570 young children, attending our laboratory, we retrospectively selected 355 patients (14% 3-4-year-olds, 48% 4-5-year-olds, and 38% 5-6-year-olds) who carried out spirometric tests for the first time. The indications for such tests were history of asthma (70%), followed by chronic cough (20%) and other miscellaneous conditions (10%).Eighty-eight, 175, and 92 children performed one, two, and three acceptable tests respectively. Forced expired volume in 1 sec (FEV1) and forced vital capacity (FVC) did not differ significantly between attempts in children performing either two or three attempts. Forced expiratory time (FET), i.e., the total time required for the forced expiratory maneuver, was 1.7 +/- 0.1 sec (mean +/- SEM), and was no greater than 1 sec in 21.3% of all tested children. Consequently, FEV1 does not appear to be well-suited to this age group. Forced expiratory volume in 0.50 and 0.75 sec (FEV0.5, FEV0.75) were thus measured in the group of children performing three attempts (n = 92), and there was no statistical difference between attempts. In 267 children performing two or three tests, the ATS criteria of reproducing FEV1 and FVC within less than or equal to 0.1 L seemed to be preferable in this young population, indeed, more than 70% of the tested children presented their two best efforts (FVC and FEV1) not varying by more than 0.1 L. individual coefficients of variation (CV = SDI mean x 100%) over three tests for FEV1 and FVC were 6.71 +/- 0.53% and 6.35 +/- 0.41% (mean +/- SEM), respectively.These results show that forced expiratory tests are not always feasible in young children, but that 55% (196/355) of our selected population performed reliable maneuvers (at least two FVC and FEV1 reproducible within 0.1 L), provided that they were supervised by a carefully trained pediatric medical staff.
