| 摘 要： | 目的：探讨支气管哮喘患者舒张试验中气道阻力（Raw)的变化及诊断价值。方法：对哮喘患者进行支气管舒张试验，测定1s用力呼吸气容和（FEV1）和Raw，观察二者前后变化情况。结果：①哮喘患者舒张试验阳性率68％（20／31）；②支气管舒张试验阳性和阴性组试验后FEV1增加的百分率比较差异有显著性（P＜0．05）；③在舒张试验阳性和阴性两组中的哮喘患者其舒张试验后Raw均显著降低。结论：哮喘舒张试验后Raw的降低较FEV1的增高率更具有诊断价值。

| Abstract: | OBJECTIVE: To discuss the variation of resistance of airway (Raw) and the diagnostic value of the bronchus diastole test for asthma patient. METHODS: The forced expiratory volume of the first second (FEV1) and Raw were measured. RESULTS: 1. The positive rate of FEV1 increase after the test was 68% (20/31). 2. There was a significant difference in percentage of FEV1 increase after the test between positive group and negative group. 3. After the bronchus diastole test, the Raw decreased significantly in both groups. CONCLUSION: The decrease of Raw after bronchus diastole test is more valuable for the asthma diagnosis than that of FEV1. |
