本文对健康不吸烟者30例和哮喘缓解期病人32例进行了最大呼吸气流速—容量测定。测验结果表明,缓解期病人与健康组对照有明显差异,但吸入支气管扩张剂氨茶硷以后,与健康对照组无显著差异。这说明哮喘缓解期病人的小气道功能处于病态,吸入支气管扩张剂后,周围气道阻塞得以改善。因而推测平滑肌痉挛为哮喘病人气道阻塞的最重要因素。因此,小气道功能检查有助于诊断病情,判定疗效。
In this paper, the maximum respiratory flow-volume was measured in 30 healthy non-smokers and 32 patients in asthma remission. The test results show that the remission of patients and healthy control group were significantly different, but the inhalation of bronchodilator ammonia theophylline, and the healthy control group no significant difference. This shows that patients with remission of asthma small airway function in the pathological, inhaled bronchodilator, peripheral airway obstruction can be improved. Therefore, it is speculated that smooth muscle spasm is the most important factor of airway obstruction in asthma patients. Therefore, small airway function tests help diagnose the disease, determine the efficacy.
