Using a modification of the forced oscillation technique we have measured respiratory resistance before and after nebulised salbutamol therapy in 32 wheezing children aged 7 months to 3 years 7 monts. 12 of the children were also studied in a total body plethysmograph. No child under 18 months of aged showed a greater than 5% fall in resistance or any fall in thoracic gas volume. In contrast, 18 of 20 children over 20 months of age showed a fall in resistance greater than 20%.
我们采用改良的强迫振荡技术,测量了32名年龄在7个月至3岁7个月的喘息儿童在雾化沙丁胺醇治疗前后的呼吸阻力。其中12名儿童还使用全身体积描记器进行了研究。18个月以下的儿童中,没有一名儿童的阻力下降超过5%,或胸腔气体容积下降。相比之下,20名20个月以上的儿童中有18名的阻力下降超过20%。
