不同年龄阻塞性睡眠呼吸暂停低通气综合征患者的睡眠监测

Polysomnography of obstructive sleep apnea-hypopnea syndrome in different age persons

目的:分析不同年龄阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome,OSAHS)患者的多导睡眠监测特点。方法:比较青年组72例、中年组219例、老年组28例的多导睡眠监测(polysomnography,PSG)资料。结果:青年组呼吸暂停低通气指数(apnea hypopnea index,AHI)平均(53.5±31.4)次/h最高,中年组次之(44.1±25.9)次/h,老年组最低(25.9±18.2)次/h,3组之间均存在差异有统计学意义(P>0.05)。睡眠结构3组类似。最低血氧饱和度(SaO2)以青年组降低最为明显,中年组、老年组次之。3组之间在呼吸紊乱导致的微觉醒指数(arousal index,ArI)及一夜睡眠中总的微觉醒指数均差异有统计学意义(P<0.05),而腿动性微觉醒指数和自发性微觉醒指数差异无统计学意义(P>0.05)。结论:OSAHS患者以青年组呼吸紊乱及缺氧程度最严重,中年组次之,老年组病情最轻,但睡眠结构紊乱的程度基本接近。

Objective： To analyze the characteristics of polysomnography in different age persons with obstructive sleep apnea-hypopnea syndrome. Methods： 32-guide polysomnography was monitored in 72 young, 219 middleaged and 28 elderly patients with obstructive sleep apnea-hypopnea syndrome, and the results were analyzed by pelysmith. Results： Although the apnea hypopnea index （AHI） of the young was highest, of middle-aged patients was second, and of elderly patients was lowest, the sleep constructs of all three groups were similar. Apnea hypopnea inducing arousal index （ArI） and total ArI of the three groups were significantly different（ P 〈 0.05）. Conclusions： Excluding the similar sleep structure disorder, sleep disorder and low blood oxygen are most serious in young patients.
