We have evaluated the influence of nonrapid eye movement (NREM), REM sleep, and arousal on abdominal muscle contractions during snoring and/or obstructive apnea in 10 prepubertal children. All children were known habitual snorers and eight had a sleep apnea index above 10. During stage 3-4 non-REM sleep, non-apneic breathing with snoring was always associated with the presence of expiratory abdominal muscle electromyogram (EMG) discharges. During non-REM sleep apneas, abdominal muscle EMG discharges increased from the beginning to the end of each apnea. Termination of non-REM sleep apnea was marked by an "EEG arousal" in 12% of the apneic events and by a "movement arousal" in the other 88%. The highest abdominal muscle EMG discharge was always observed during the arousal response. During "phasic" REM sleep, abdominal muscle EMG discharges were absent during both nonapneic breathing (with or without snoring) and obstructive apneas. All REM sleep apneas ended with a "movement arousal," during which abdominal muscle EMG discharges were observed. Thus, abdominal muscle EMG discharges associated with "arousal" were seen independent of the immediately preceding sleep state.
我们评估了非快速眼动（NREM）、快速眼动睡眠和觉醒对10名青春期前儿童打鼾和/或阻塞性呼吸暂停期间腹部肌肉收缩的影响。所有儿童均为习惯性打鼾者，其中8名儿童的睡眠呼吸暂停指数高于10。在3-4期非快速眼动睡眠期间，伴有打鼾的非呼吸暂停呼吸总是与呼气时腹部肌肉肌电图（EMG）放电有关。在非快速眼动睡眠呼吸暂停期间，腹部肌肉EMG放电从每次呼吸暂停开始到结束都会增加。12%的呼吸暂停事件中，非快速眼动睡眠呼吸暂停的终止以“脑电图觉醒”为标志，另外88%以“运动觉醒”为标志。在觉醒反应期间始终观察到最高的腹部肌肉EMG放电。在“快速眼动”睡眠阶段，无论是非呼吸暂停呼吸（伴或不伴打鼾）还是阻塞性呼吸暂停期间，腹部肌肉EMG放电均不存在。所有快速眼动睡眠呼吸暂停均以“运动觉醒”结束，在此期间观察到腹部肌肉EMG放电。因此，与“觉醒”相关的腹部肌肉EMG放电与紧接在前的睡眠状态无关。
