摘　　要：目的探讨右肺中叶综合征患儿治疗前后的肺功能变化及其临床意义。方法将30例儿童右肺中叶综合征住院患儿分成两组,≤4岁组患儿20例选用2600型肺功能仪,>4岁组患儿10例选用MIR型肺功能仪,分别在治疗前和治疗后做肺功能测定,比较其治疗前后的肺功能参数的变化。2600型肺功能仪测定的主要参数取75%潮气量与最高呼气流速之比(25/PF)和潮气量与最高潮气呼气流速之比(%V-PF)2个参数来反映0～4岁组患儿的肺功能变化,MIR型肺功能仪测定的主要参数取最大肺活量(FVC)、1秒率(FEV1)和最高呼气流速(PEF)共3个参数来反映>4岁组患儿的肺功能变化。结果≤4岁组治疗前肺功能参数的测定值分别为25/PF=0.42±0.08,%V-PF=0.28±0.03;治疗后的肺功能参数的测定值为25/PF=0.58±0.12,%V-PF=0.39±0.06。两者治疗前后比较差异有显著性,t=4.21,3.82;均P<0.05。>4岁组治疗前肺功能参数的测定值分别为FVC=1.75±0.32,FEV1=1.36±0.52,PEF=2.56±0.78;治疗后的肺功能参数的测定值分别为FVC=2.37±0.78,FEV1=2.08±0.65,PEF=3.68±0.80。治疗前后比较,分别t=3.05,2.98,3.12;均P<0.05。结论右肺中叶综合征患儿治疗前后的肺功能变化是明显的,治疗后肺功能可恢复正常。Objective To study the changes of pulmonary function in children with right lung middle lobe syndrome before and after treatment.Methods Thirty children with right lung middle lobe syndrome were classified into two age groups：≤4 years old and 〉4 years old.Pulmonary function was tested by the 2600-type and the MIR-type pulmonary function spirometry in the ≤4 years and the 〉4 years age groups,respectively before and after treatment.Terminal flows/peak expiratory flow（25/PF）and the percentage of tidal volume to peak tidal expiratory flow（% V-PF）were measured in the 〈4 years age group.Forced vital capacity（FVC）,forced expiratory volume in one second（FEV1）and peak expiratory flow（PEF）were measured in the 〉4 years age group.Results The values of 25/PF and %V-PF in the ≤4 years age group were 0.42±0.08 and 0.28±0.03,respectively before treatment.The values were improved after treatment（0.58±0.12 and 0.39±0.06 respectively）（P〈0.05）.The values of FVC,FEV1 and PEF were 1.75±0.32,1.36±0.52 and 2.56±0.78,respectively in the 〉4 years age group before treatment.The values were also improved after treatment（2.37±0.78,2.08±0.65 and 3.68±0.80 respectively）（P〈0.05）.Conclusions There are significant differences in the pulmonary function before and after treatment in children with right lung middle lobe syndrome.The pulmonary function can return to normal after treatment.
