To assess obstructive sleep apnea syndrome (OSAS) severity among pediatric patients. Design. A retrospective review of charts and polysomnography (PSG) results.
Apnea-hypopnea index (AHI) and the cumulative duration of sleep while O(2)SAT was <91% were determined in 389 patients with OSAS. Patients with AHI ranging <5, 5 to 15, 16 to 30, and >30, had mean lowest observed O(2)SAT values of 88% +/- 8%, 85% +/- 9%, 78% +/- 12%, and 69% +/- 13%, respectively. The patients spent a mean of 3.5% +/- 9.2 % of their sleep time with O(2)SAT < 91%. AHI values showed a poor linear correlation with the lowest measured O(2)SAT values. Body mass index percentiles showed no significant linear correlation with AHI values or with the lowest measured values of O(2)SAT.
Values of AHI cannot accurately predict severity of oxyhemoglobin desaturation in pediatric OSAS and vice versa. No significant correlation between body mass index percentiles and severity of OSAS was established.
评估儿科患者阻塞性睡眠呼吸暂停综合征（OSAS）的严重程度。设计：对病历和多导睡眠图（PSG）结果进行回顾性分析。
测定了389例OSAS患者的呼吸暂停低通气指数（AHI）以及血氧饱和度（O₂SAT）<91%时的累计睡眠时间。AHI范围<5、5至15、16至30和>30的患者，其观察到的最低O₂SAT值的均值分别为88%±8%、85%±9%、78%±12%和69%±13%。患者睡眠期间O₂SAT<91%的时间均值为3.5%±9.2%。AHI值与测量到的最低O₂SAT值呈弱线性相关。体重指数百分位数与AHI值或测量到的最低O₂SAT值均无显著线性相关。
AHI值不能准确预测小儿OSAS中氧合血红蛋白去饱和的严重程度，反之亦然。体重指数百分位数与OSAS严重程度之间未建立显著相关性。
