吸烟对鼻气道阻力影响的初步探讨
Influence of smoking on nasal airway resistance
【摘要】 目的 :探讨吸烟对鼻气道阻力 ( NAR)的影响。方法 :采用前鼻测压法 ,对 40例正常不吸烟者 (对照组 )、41例轻度吸烟者 (轻度吸烟组 )、42例重度吸烟者 (重度吸咽组 )的单侧及总鼻腔NAR进行测定、比较。结果 :重度吸烟组鼻粘膜减充血前单侧及总鼻腔 ( NAR)与对照组比较有显著性差异 ( P <0 .0 5) ,鼻粘膜减充血后则无显著性差异 ( P >0 .0 5) ;轻度吸烟组鼻粘膜减充血前后均无显著性差异 ( P >0 .0 5)。结论 :长期、重度吸烟可导致 NAR的增高 ;这种增高与鼻粘膜的血管因素有关。
【Abstract】 Objective:To discuss the influence of smoking on nasal airway resistance (NAR).Method:The unilateral and total NAR of 40 normal controls,41 slight smokers and 42 heavy smokers were evaluated by anterior rhinomanometry before and after nasal decongestion.Result:Before nasal decongestion,the unilateral and total NAR of heavy smokers increased significantly (P< 0.05 ) compared with that of normal controls.After decongestion,there was no significant difference (P> 0.05 ).Whenever before or after decongestion,there was no significant differnce between slight smokers and normal controls (P> 0.1 ).Conclusion:Long time and heavy smoking can enhance the NAR,which may be due to the chang of blood vessels in nasal mucosa.
