OSAHS与单纯鼾症儿童睡眠效率及睡眠结构分析

The Study of Sleep Efficiency and Characteristics in Pediatric Obstructive Sleep Apnea Hypopnea Syndrome and Primary Snoring Children

目的探讨儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)与单纯鼾症(PS)儿童夜间睡眠效率和睡眠结构的分析。方法对32例OSAHS儿童和27例PS儿童进行全夜多导睡眠图(PSG)监测,观察夜间睡眠效率和睡眠结构各项指标,并进行比较。结果OSAHS组患儿的睡眠效率显著低于PS组(P<0.01);与PS组及正常值比较,OSAHS组的睡眠结构存在以下差异睡眠Ⅰ期显著高于PS组和正常值(P<0.01),睡眠Ⅱ期、慢波睡眠、快动眼睡眠显著低于PS组和正常值(P<0.01)。PS组的睡眠结构分析基本均在正常范围,但睡眠效率有所下降。结论OSAHS可引起儿童睡眠结构紊乱和睡眠效率下降。

Objective To investigate sleep efficiency and characteristics in pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) and primary snoring (PS) children. Methods 32 children with OSAHS, and 27 PS children were monitored by nocturnal polysomnography (PSG). The parameters of sleep efficiency(SE) and sleep composition, including apnea/hyponea index(AHI),stageⅠ sleep(S1)%, stageⅡ sleep(S2)%, slow wave sleep(SWS)% and rapid eye movement(REM)%, were recorded and compared between the two groups. Results In OSAHS group,the SE was significantly lower than that in PS group (P<0.01). Compared with PS and normal range, OSAHS group had increased S1%(P<0.01), and decreased S2%, SWS%, and REM%(P<0.01). In PS group,the change of sleep composition was in normal range, but SE decreased. Conclusion OSAHS could decrease sleep efficiency and result in the change of sleep composition in children.
