The study was designed to evaluate whether results of a single overnight recording session are sufficient for the study of sleep profiles and detection of apneas in infants, or whether it would be beneficial to extend the recording period. Nineteen infants were recorded during successive nights. Eight of the 19 infants were studied after an idiopathic apparent life-threatening event, whereas the other 11 were healthy. There were 13 boys and six girls, with a median age of 11 weeks (range 5-36 weeks). All infants were recorded polygraphically during 2 nights, and 11 were recorded during 3 successive nights. No significant difference was observed between any of the following variables, regardless of the number of nights for which the recording was performed: total recording time, total sleep time, delay in sleep onset, time awake, percent of rapid eye movement or nonrapid eye movement sleep, mean respiratory rates, density and duration of central, obstructive or mixed apneas. The frequency of obstructed breathing events for each infant did not differ significantly from 1 night to the next. The present study indicates that under adequate study conditions, recordings of a single night can reliably describe the frequency of central and obstructive apneas in infants.
本研究旨在评估单次夜间记录时段的结果对于婴儿睡眠状况研究及呼吸暂停检测是否足够，或者延长记录时间是否有益。对19名婴儿进行了连续多晚的记录。19名婴儿中有8名是在发生特发性明显危及生命事件后进行研究的，另外11名是健康婴儿。其中有13名男孩和6名女孩，中位年龄为11周（范围5 - 36周）。所有婴儿均进行了两晚的多导睡眠记录，11名婴儿进行了连续三晚的记录。无论记录的夜晚数量如何，在以下任何变量之间均未观察到显著差异：总记录时间、总睡眠时间、入睡延迟、清醒时间、快速眼动或非快速眼动睡眠百分比、平均呼吸频率、中枢性、阻塞性或混合性呼吸暂停的密度和持续时间。每个婴儿的呼吸阻塞事件频率在不同夜晚之间无显著差异。本研究表明，在适当的研究条件下，单次夜间记录能够可靠地描述婴儿中枢性和阻塞性呼吸暂停的频率。
