【摘要】 目的:探讨睡眠呼吸暂停综合征(sleep apnea syndrom e,SAS)患者的临床特点与年龄及肥胖的相关性。方法:采用多导睡眠监测仪(PSG)对116例SAS患者进行睡眠监测,按体重指数(BM I)分为肥胖组(57例)与非肥胖组(59例),按年龄分为老年组(26例)与中青年组(90例),分析对应组间SAS患者的临床特点。结果:呼吸暂停低通气指数(AH I)、最长呼吸暂停持续时间(LAT)、平均呼吸暂停持续时间(MAT)肥胖组较非肥胖组高,最低血氧饱和度(LSaO2)、平均血氧饱和度(MSaO2)肥胖组较非肥胖组低,差异均有显著性(P<0.005~P<0.001)。颈围、BM I老年组较中青年组低,差异均有显著性(P<0.01~P<0.005);AH I、LAT老年组较中青年组低,LSaO2、MSaO2老年组较中青年组高,差异均有显著性(P<0.05~P<0.005)。结论:肥胖组SAS患者严重程度较非肥胖组SAS患者重,老年组SAS患者严重程度较中青年组SAS患者轻。更多还原

【Abstract】 Objective:To investigate the correlation between sleep apnea syndrome（SAS） and the age and body weight.Methods:One hundred and sixteen patients with SAS were diagnosed by polysomnography（PSG） and classified into the aged group and middle-aged group,the obesity group and non-obesity group.Results:The apnea hypopnea index（AHI）,longest apnea time（LAT） and mean apnea time（MAT） of the obesity group were significantly higher than those of the non-obesity group,and the index of lowest arterial O₂ saturation（LSaO₂） and mean arterial O₂ saturation（MSaO₂） were lower than those of the non-obesity group（P<0.005 to P<0.001）.Both the body mass index（BMI） and neck circumference were lower in the aged group than in the middle-aged group（P<0.01 to P<0.005）;AHI,LAT and MAT were lower in the aged group comparatively.LSaO₂ and MSaO₂ were significantly higher in the aged group than those in the middle-aged group（P<0.05 to P<0.005）.Conclusions:The severity of SAS is positively correlated with body weight and negatively correlated with age.更多还原
