阻塞性睡眠呼吸暂停低通气综合征儿童与成人多导睡眠监测对照分析

目的：比较儿童与成人阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者在多导睡眠监测（PSG）各项指标上的差异。方法：对儿童和成人OSAHS患者行PSG检查，观察呼吸暂停指数（AI）、低通气指数（HI）、呼吸暂停低通气指数（AHI）、最低血氧饱和度（LSaO2），最长呼吸暂停时间等项指标，并分析两组的睡眠结构，包括非快动眼睡眠（NREM）各期及快动眼睡眠（REM）期占睡眠时间百分比以及微觉醒指数，并分组进行比较。结果：儿童组AI、HI、AHI、最长呼吸暂停时间等项指标均小于成人组，差异有统计学意义，但LSaO2与成人组相比差异无统计学意义。儿童组睡眠结构与正常儿童相近，睡眠结构及微觉醒指数与成人组比较差异有统计学意义。结论：儿童与成人OSAHS患者在PSG各项指标上差异明显，成人PSG诊断标准不适用于儿童患者。儿童PSG诊断标准有待进一步研究来确定。

Polysomnography parameters of obstructive sleep apnea hypopnea syndrome: a comparison between children and adults

To explore the differences of polysomnography parameters of obstructive sleep apnea hypopnea syndrome (OSAHS) between children and adults. Methods: The sleep of 37 pediatric OSAHS and 35 adult OSAHS patients was monitored. Several parameters, including the apnea index(AI), hypopnea index(HI), apnea hypopnea index(AHI), the lowest oxygen saturation(LSaO2) and the longest apnea time were counted, and the percent of stages of NREM and REM, including the microarousal index was calculated. Results: Many parameters, such as AI, HI, AHI, LSaO2 and the longest apnea time were significantly different between the two groups. The sleep structure of pediatric OSAHS was similar with that of normal children, but different from that of the adult group. Conclusion: The difference of PSG parameters is significant between pediatric OSAHS and adult OSAHS. The standard of adult PSG does not fit for child PSG.
