BACKGROUND
It is unknown whether adenotonsillectomy influences changes of position during sleep in children with obstructive sleep apnea syndrome (OSAS). The aim of this study was to evaluate the effect of adenotonsillectomy on changes of position during sleep as determined by polysomnography in children with OSAS.
METHODS
Forty-four polysomnograms from 22 children with OSAS were analyzed. We compared the frequency of positional changes during sleep and the distribution of sleep positions before and after adenotonsillectomy.
RESULTS
Adenotonsillectomy significantly improved all respiratory parameters studied. The arousal index and sleep efficiency were improved among the sleep parameters. There was a significant decrease in the total number of positional changes during sleep (p < 0.001) and positional change index (p < 0.001). The proportion of sleep time spent in the supine position was significantly increased (p = 0.001), and the proportions spent in lateral (p = 0.003) and up (p = 0.018) positions were significantly decreased.
CONCLUSION
Significant changes were found in the frequency of positional changes during sleep and the distribution of sleep positions in children with OSAS after adenotonsillectomy.
背景
目前尚不清楚腺样体扁桃体切除术是否会影响阻塞性睡眠呼吸暂停综合征（OSAS）患儿睡眠时的体位变化。本研究旨在评估腺样体扁桃体切除术对 OSAS 患儿睡眠时体位变化的多导睡眠图（PSG）检测结果的影响。
方法
对 22 例 OSAS 患儿的 44 次 PSG 进行分析。我们比较了腺样体扁桃体切除术前、后睡眠时的体位变化频率和睡眠体位分布。
结果
腺样体扁桃体切除术显著改善了所有研究的呼吸参数。睡眠参数中的觉醒指数和睡眠效率得到改善。睡眠时体位变化的总次数（p<0.001）和体位变化指数（p<0.001）显著减少。仰卧位睡眠时间的比例显著增加（p=0.001），而侧卧位（p=0.003）和上位（p=0.018）的睡眠时间比例显著减少。
结论
腺样体扁桃体切除术后，OSAS 患儿睡眠时体位变化的频率和睡眠体位分布发生了显著变化。
