阻塞性睡眠呼吸暂停低通气综合征不同年龄PSG睡眠结构特点

目的 分析阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者不同年龄PSG睡眠结构的特点,以上指导对OSAHS的诊断与治疗.方法 对因睡眠打鼾就诊、整夜多导睡眠图检查诊为OSAHS的患者603例,按年龄将其分为四组儿童组(8～14岁)、青年组(15～40岁)、中年组(41～59岁)、老年组(＞60岁)进行PSG的特点比较分析.结果 在打鼾就诊人群中OSAHS患病率为89.60%,年龄、肥胖、颈围、体重指数(BIM)均为高危因素.老年组绝大多数以1、2期睡眠为主,其分别占睡眠时间(45.6±2.8)%、(31.3±8.5)%,且觉醒的次数多达(123.3±32.5)次,总的睡眠时间/记录时间(63.9±23.6)%、快速动眼睡眠时间/总睡眠时间(1.6±0.5)%、非快速动眼睡眠时间/总睡眠时间(55.8±21.4)%,显示明显减少(P＜0.05).儿童的3、4期睡眠明显高于老年组分别占[(30.4±14.6)%、(48.6±17.5)%],觉醒次数(65.8±34.5)次,明显减少(P＜0.05).结论 不同的年龄组OSAHS患者的睡眠结构有着显著不同的特点,可以根据这些不同的特点指导临床诊断和治疗.

Polysomnography''s characteristics of patients with obstructive sleep apnea-hypopnea syndrome in different ages

Objective To study the polysomnography's characteristics of patients with obstructive sleep apnea-hypopnea syndrome(OSAHS),and know more about polysomnography(PSG) in different ages.Methods 603 patients snoring during sleep were examined by all-night PSG and nocturnal oxygen saturation monitor.We analyzed the PSG's characteristics of the patients divided into 4 groups according to the different ages of apnea-hypopnea index(AHI).Results The morbidity rate was 89.60% in the snorers.There was significant difference among PSG in different ages.Age,obesity,neck circumference and body index number(BMI) were liability factor of OSASH.Compare to others groups,the aged group presented more significant changes in sleep structures,less sleep efficiency and more stage 1 and stage 2,less stage 3 and stage 4,more wakefulness and less sleep.Conclusion It shows significant difference among PSG in different ages,which can irect the diagnosis and treatment of OSAHS.
