To compare the new American Academy of Sleep Medicine (AASM) criteria for scoring sleep with the previous Rechtschaffen and Kales (R&K) criteria in a cohort of children with primary snoring, obstructive sleep apnea syndrome (OSAS) and normal controls.
Polysomnography was performed in 26 consecutive children with primary snoring (13 males, mean age 6.2 years, SD 3.2), in 39 with OSAS (24 males, mean age 6.1 years, SD 3.0), and in 10 age-matched normal controls.
Compared to the other groups, OSAS children showed a lower percentage of slow-wave sleep, using both R&K and AASM criteria; they also showed a higher percentage of stage shifts, and N1, using the AASM criteria. Children with primary snoring showed a higher percentage of N1, compared to controls.
These results indicate that the use of the new AASM criteria seem to disclose more differences in sleep parameters than the R&K rules in children with OSAS.
The AASM criteria seem to disclose a high degree of sleep fragmentation in children with OSAS, mostly related to the repeated occurrence of N1.
比较新的美国睡眠医学学会（AASM）睡眠评分标准与之前的雷赫曼和卡勒斯（R&K）标准在原发性打鼾、阻塞性睡眠呼吸暂停综合征（OSAS）和正常对照组患儿中的应用。
对 26 例原发性打鼾（男 13 例，平均年龄 6.2 岁，标准差 3.2）、39 例 OSAS（男 24 例，平均年龄 6.1 岁，标准差 3.0）和 10 例年龄匹配的正常对照组患儿进行了多导睡眠图检查。
与其他组相比，OSAS 患儿的慢波睡眠百分比较低，使用 R&K 和 AASM 标准均如此；使用 AASM 标准时，他们的 stage shifts 和 N1 百分比也更高。与对照组相比，原发性打鼾患儿的 N1 百分比更高。
这些结果表明，与 R&K 规则相比，新的 AASM 标准似乎在 OSAS 患儿的睡眠参数上显示出更多差异。
AASM 标准似乎揭示了 OSAS 儿童睡眠碎片化程度较高，主要与 N1 的反复发生有关。
