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.
