变态反应性鼻炎变应原鼻内激发试验前后鼻阻力观察

Observation of Nasal Resistance before and after Nasal Challenge Testing on Allergic Rhinitis Patients

观察125例变态反应性鼻炎变应原鼻内激发试验前后鼻阻力变化。结果示变应原鼻内激发试验阳性者其鼻总阻力明显高于正常对照组和阴性组;鼻阻力激发后变化超过0.1kPa/(s.L)或原基线30％可作为激发试验阳性的客观参考指标。

Allergen nasal challenge tests in 125 allergic rhinitis cases were observed. The results showed that nasal resistance of positive allergen nasal challenge group was significantly higher than normal control group and negative group. The nasal resistance after allergen nasal challenge test exceeded 0. lkPa/(s-L)or went beyond the guideline 30%higher that it might be an objective reference index of positive allergen nasal challenge test by rhinomanometry.
