吸烟者与非吸烟者的肺功能对比观察

摘要

Objective To study the application of multiple row spiral CT pulmonary function technology to compare lung function between smokers and non-smokers. Methods The study selected 100 smokers as the experi-ment group and 100 non-smokers as the control group. Their lung function was detected by multiple row helical CT, including aortic arch, bronchus divides inspiratory and expiratory phase of PL-(900 - 950), and MLD. Results Compared with the control group, the value FVC, FEV1 , and FEV1 / FVC was significantly lower in the experiment group than in the control group (P < 0. 05). The value of PL-(900 - 950) and MLD showed no difference between the two groups under the inspiratory phase (P > 0. 05), but it showed certain difference under the expiratory phase (P < 0. 05). Conclusion The lung function of non-smokers is better than smokers, and it can provide the basis for clinical diagnosis and treatment under the expiratory phase by CT.%目的：探讨运用多排螺旋 CT 肺功能技术对吸烟者与非吸烟者的肺功能状态。方法选取100例吸烟者,作为研究组,并选取100例一般资料无显著差异的非吸烟者作为对照组。对两组的肺功能指标进行检测,并通过多排螺旋 CT,检测两组主动脉弓、支气管分叉处吸气相和呼气相的 PL-(900-950)、MLD 的扫描值。结果与对照组对比,研究组用力呼气量占预计值百分比(FVC)、第一秒呼气容积占预计值百分比(FEV1)、第一秒呼气容积占用力呼气量百分比(FEV1/ FVC)等肺功能指标明显低于对照组,差异有统计学意义(P <0．05)。在吸气相下,两组主动脉弓、支气管分叉处 PL-(900-950)、MLD 的扫描值相似,差异没有统计学意义(P >0．05)。在呼气相下,两组主动脉弓、支气管分叉处 PL-(900-950)、MLD 的扫描值具有明显差异,具有统计学意义(P <0．05)。结论非吸烟者的肺功能明显优于吸烟者,在呼气相下借助 CT 诊断,可为临床诊断治疗提供依据。
