The purpose of this study was to ascertain whether the middle components of the auditory evoked response could be obtained consistently from normal young children during sleep. The wave pattern of the response was unstable and was not reproducible in sleeping children. Comparing the detectability of each peak in waking children with that of each peak in sleeping children, there was little difference in the detectabilty of the Po peak between the two test conditions, and the Na peak was only about 10% lower in sleeping subjects than in waking ones. However, a considerable decrease in the detectability of the Pa peak was found during sleep. Later peaks, such as the Nb and Pb peaks, which are usually elicited in waking adults, could scarcely be found in children, either in the sleeping or in the wakeful state. In this study, no clear difference of detectability in each peak could be demonstrated between the two filter conditions. From these results, it is concluded that the middle components of the electroencephalic response in sleep differ from those in the waking state, especially in children. Moreover, it seems that the decrease in the appearance of the response during sleep may be related to the depth of sleep. Po-Na may be the most suitable index for electric response audiometry in young children.
本研究的目的是确定在睡眠期间能否从正常幼儿身上持续获取听觉诱发电位的中间成分。该反应的波形不稳定，在睡眠中的儿童身上无法重复。比较清醒儿童与睡眠儿童中每个波峰的可检测性，两种测试条件下Po波峰的可检测性几乎没有差异，睡眠受试者的Na波峰仅比清醒受试者低约10%。然而，发现睡眠期间Pa波峰的可检测性显著降低。在儿童中，无论是睡眠状态还是清醒状态，通常在清醒成年人中引出的较晚波峰，如Nb和Pb波峰，几乎都无法检测到。在本研究中，两种滤波条件下每个波峰的可检测性没有明显差异。从这些结果可以得出结论，睡眠中脑电图反应的中间成分与清醒状态不同，尤其是在儿童中。此外，睡眠期间反应出现次数的减少似乎可能与睡眠深度有关。Po-Na可能是幼儿电反应测听的最合适指标。
