目的:探讨吸烟对气道麻醉效果的影响。方法:将吸烟指数≤400 年支和> 400 年支分为轻度(29 例) 、重度(22 例)吸烟两组,与非吸烟组(20 例) 进行纤维支气管镜检查( 简称纤支镜) 常规麻醉( 雾化吸入利多卡因200mg,纤支镜插入后注入50 ～100mg) 效果比较。结果:轻、重度吸烟两组与非吸烟组常规麻醉的效果比较差异有显著性(χ2 分别为4 .83 和6.44,均P< 0.05) 。结论:吸烟者气道亦存在慢性非特异性炎症和气道高反应性,吸烟者纤支镜检查时麻醉用药( 利多卡因)用量需增加
Objective: To investigate the effect of smoking on airway anesthesia. Methods: The smoking index ≤400 years and> 400 years were divided into mild (29 cases), severe (22 cases) smoking and non-smoking group (20 cases) for bronchoscopy ) Conventional anesthesia (atomization inhaled lidocaine 200mg, bronchoscopy inserted after injection of 50 ~ 100mg) effect comparison. Results: There was significant difference between the two groups in light and severe smoking and the non-smoking group (χ2 = 4.83 and 6.44, respectively, P <0.05). Conclusion: There is also chronic nonspecific inflammation and airway hyperresponsiveness in the smoker’s airway. The dosage of anesthetic drug (lidocaine) should be increased in smokers with bronchoscopy
