目的 探讨必瑞通缓解鼻塞症状的效果。方法 应用美国Eccovision鼻声纳测量仪对慢性鼻炎 42例、鼻中隔偏曲 2 2例、肥厚性鼻炎和鼻息肉 12例患者进行测试。结果 必瑞通治疗慢性鼻炎前后的鼻气道阻力 (NAR)分别为 0 0 5 1和 0 0 42cmH2 O/(L·s) ,鼻阻力缓解率为 17 7% ;鼻腔最小截面积 (MCA)分别为 0 44cm2 和 0 5 1cm2 ;治疗鼻中隔偏曲前后的NAR分别为 0 0 6和 0 0 5 1cmH2 O/(L·s) ,缓解率为 15 % ;MCA分别为 0 40cm2 和 0 44cm2 ,但只对前段鼻中隔偏曲有效 ;患者的主观鼻塞症状有缓解 ;对于肥厚性鼻炎无效 ;结论 必瑞通是一种安全、简便、有效的鼻塞缓解装置 ,可广泛应用于临床。
Objective To investigate the effect of Brite on relieving the symptoms of nasal obstruction. Methods 42 cases of chronic rhinitis, 22 cases of nasal septum deviation, 12 cases of hypertrophic rhinitis and nasal polyps were tested by the American Eccovision nasal sonograph. Results Nasal airway resistance (NAR) before and after treatment of chronic rhinitis with Betarit were 0 0 5 1 and 0 0 42cmH 2 O / (L · s), respectively. The response rate of nasal resistance was 17 7%. The minimum nasal area (MCA) Respectively, 0 44 cm 2 and 0 51 cm 2. The NAR before and after the treatment of nasal septum deviation were 0 0 6 and 0 0 5 1 cmH 2 O / (L · s), respectively, with a remission rate of 15%. MCA was 0 40 cm 2 and 0 44 cm 2 respectively Only partial anterior nasal septum deviation effective; patients with subjective nasal congestion symptoms alleviate; for hypertrophic rhinitis is not effective; Conclusion Bi Rui Tong is a safe, simple and effective device for nasal congestion can be widely used in clinical.
