摘　　要：目的 :肺功能检查广泛应用于临床医学和流行病学调查 ,但其对单侧主支气管阻塞(MBO)的评价则尚未见报道。方法 :对 6 0例 (男 31、女 2 9、年龄 4 3.6± 15.8岁 )MBO病者测定其肺通气功能改变。结果 :MBO左与右侧之比为 3:1。主要病因为支气管肺癌 (占 56 .7% )和支气管内膜结核 (占 35.0 % )。完全性阻塞者有 14例 ,呈限制性改变 ,不完全性阻塞者 4 6例 ,呈阻塞性改变。典型的固定型MBO不完全性阻塞的流速 -容量曲线呈双蝶型 ,吸气后期及呼气后期流速均明显受限 ,见于 17.4 %患者。MBO病者经治疗后肺通气功能指标有改善。结论 :MBO时肺功能检查有相应改变 ,典型者其流速 -容量曲线呈双蝶型 ,对诊断有较大参考意义。Objective: Few Pulmonary function testing (PFT) study was related to Lateral main bronchus obstruction (LMBO). This study is designed to understand the lung function change in LMBO. Method: 60 patients with LMBO [male 31, female 29, aged 17～69 (43.6±15.8) years) ]were studied with flow_volume test and bronchoscope. Result: The predominant obstruction was in the left main bronchus (the ratio of left to right being 3∶1). The main cause was bronchial cancer(56.7%), followed by bronchial tuberculosis (35.0%). Complete obstruction of LMBO was found in 14 cases with the feathure of restrictive ventilation. Obstructive ventilation was found in the other 36 patients with incomplete LMBO. Typical flow_volume curve of fixed incomplete LMBO, whichshowed in 17.3% patients, was obviously flow restrictive in middle to late period in both inspiratory and expiratory phase,showing butterfly_like change. Lung functions were improved in 6 cases with LMBO caused by bronchial tuberculosis after local electric knife treatment guided with bronchoscope. Conclusion:The results indicated that special attention should be paid to LMBO when flow_volume test is applied.
