| 摘 要： | 近年来40Hz听觉稳态诱发电位(ASSR)由于与中潜伏期听觉诱发电位(MLAEP)有共同的发生源,抗干扰能力强,与意识水平的关系也较为密切,所以在麻醉深度监测上逐渐受到人们的重视。本文基于ASSR的特点提出了几种有效、稳定的提取方法,并通过临床采集到的实际记录信号对各种方法的处理结果进行了比较分析,得出较为适合临床麻醉监测的提取方法。

| Abstract: | In recent years, 40Hz auditory steady state response (ASSR) has been paid more attention when the depth of anaesthesia monitored because its same source with the middle latency auditory evoked potential (MLAEP), strong anti-jamming ability and close relationship with consciousness level. This article brings forward some effective and steady methods for extracting ASSR according to its characteristics. The results of these methods are analyzed and compared based on the actual records from clinical practice. And thus an extraction method fit for monitoring the depth of anaesthesia is determined. |
