【摘要】 目的 探讨简易的夜间脉搏血氧饱和度(SpO.2)监测在初筛甚至确诊儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)中的可行性。方法 分析37名疑诊OSAHS儿童的多导睡眠仪(PSG)监测结果,得出每小时SpO.2下降≥4%次数,即氧减饱和度指数(CDI.4)。将CDI.4与呼吸暂停低通气指数(AHI)进行相关性统计学分析。结果 非OSAHS组(阻塞性呼吸暂停指数(OAI)<1次/h)6例,和OSAHS组(OAI≥1次/h,或AHI≥5次/h,伴最低SpO.2(LSpO.2 )<92%)31例。CDI.4与AHI正相关,相关系数为:0.876;CDI.4与AHI直线回归方程为:Y (AHI) =0.101*X(CDI.4)+1.496,R2=0.810,P<0.01;CDI.4≥2次/h作为诊断标准时与金标准的一致性较好。结论 CDI.4与AHI有良好相关性,CDI.4与AHI的直线回归方程成立,CDI.4可反映呼吸紊乱的频度,CDI.4≥2次/h诊断OSAHS时有较高的敏感性和特异性;SpO.2监测在初筛甚至确诊儿童OSAHS中有临床实用价值。

【Abstract】 Objective To investigate the feasibility and reliability of screening even simple diagnosing pediatric Obstructive Sleep Apnea Hypopnea syndrome (OSAHS) only by Pulse Oxygen Saturation (SpO.2) monitoring. Methods Analyzed the polysomnographic outcomes of 37 suspected OSAHS children, counted the number of desaturations exceeding 4% per hour (namely Oxygen Desaturation Index, CDI.4), and the statistical correlation between CDI.4 and Apnea Hypopnea Index(AHI) was performed. Results The investigated children
