摘　　要：目的 分析139例因打鼾就诊患者的阻塞性睡眠呼吸暂停低通气综合征（OSAHS）发生率及多导睡眠图特点,探讨鼾症患者的病情严重程度.方法 对因打鼾就诊的139例患者进行问卷调查,行多导睡眠图（PSG）监测,根据呼吸暂停低通气指数（AHI）进行分组,各指标进行组问比较,AHI、体重指数（BMI）分别和PSG监测指标作相关性分析.结果 139例患者中确诊OSAHS 121例,且重度患者比例达48%,OSAHS组BMI及颈围明显大于单纯鼾症组;OSAHS患者各组间的氧减指数（ODI）及脉氧饱和度低于90%的时间占总检测时间的百分比（TS90%）比较差异有统计学意义;相关分析提示,BMI与AHI正相关;两者与最低脉氧饱和度（LSaO2）负相关,与ODI和TS90%正相关,ODI和TS90%比LsaO2与AHI有更好的相关性.结论 因打鼾就诊患者的OSAHS发生率高,肥胖是OSAHS重要的危险因素,随着肥胖程度的增加,AHI指数越高,夜间缺氧程度越严重,且ODI和TS90%能更好地判断缺氧程度.Objective To analyze the incidence of obstructive sleep apnea hypopnea syndrome（OSAHS） and clinical characteristics of polysomnograms（PSG） in 139 patients with sleeping-snore,to explore the severity of disease in patients suffering from snoring.Methods 139 cases of patients with snoring in our hospital were enrolled in this study.A questionnaire paper and PSG were tested.The patients were divided into 4 groups according to the apnea hypopnea index（AHI）,the parameters were compared among groups,the correlations between AHI, body mass index（BMI） and parameters of PSG were analyzed.Results 121 eases were diagnosed as OSAHS,and 48% of them were severe.The BMI and neck circumference in patients of OSAHS were significantly higher than those of in normal snorers.With the progress of the disease,the significant difference was found in the oxygen desaturation index（ODI） and the percentage of the total recorded time spent below 90% oxygen sathration（TS90%） among the three OSAHS groups. BMI was positively correlated with AHI,both BMI and AHI were negatively correlated with lowest arterial oxyhemoglobin saturation（LSaOz）,positively correlated with ODI and TS90%,ODI and TS90% have better correlationship with AHI comparing to LSaOz.Conclusion OSAHS has a high morbidity rate in outpatients with snoring,and obesity could be an important risk factor in OSAHS.With the increase of BMI and AHI,the degree ofanoxia is more serious,and ODI and TS90% are better parameters.
