对28例过敏原皮试及非特异气道激发试验(NSBPT)均阳性者吸入过敏原进行特异性气道激发试验(SBPT),10例阳性(占37.5%)。过敏原皮试阳性反应程度与SBPT阳性中密切相关。SBPT阳性者在激发后10～20分钟通气功能参数下降达高峰,30分钟开始恢复,60分钟时仅2例FEV_(1.0)完全恢复。认为:SBPT检测哮喘病人的气道高反应性不如NSBPT敏感。SBPT最低吸入量应根据病人过敏原皮试阳性反应程度确定,并应正确掌握SBPT的适应症。
Specific airway provocation test (SBPT) was performed on 28 allergens skin test and non-specific airway provocation test (NSBPT) positive, and 10 cases were positive (37.5%). Allergen skin test positive reaction is closely related with SBPT positive. The ventilatory function parameters peaked 10 min to 20 min after SBPT stimulation and recovered at 30 min. Only 2 patients (FEV_ (1.0) recovered completely at 60 min). That: SBPT asthmatic patients with airway hyperresponsiveness is not as sensitive as NSBPT. SBPT minimum inhalation should be based on the degree of allergen skin test positive reaction to determine, and should correctly grasp the indications of SBPT.
