    Abstract:
    Monitoring of cerebral evoked potentials during total anesthesia provides objective data on the depth of anesthesia. Somatosensory and auditory evoked potentials (SSEP and AEP, respectively) were recorded in 48 patients (ASA physical status 1-2) before and during surgery. AEPs were assessed using a two-stimulus oddball paradigm under passive ignore conditions. Decreased amplitudes and increased latencies of mid-latency SSEP were regarded as decreased conduction of pain pulse via specific and nonspecific pathways. The amplitude of late-latency AEP indicated the level of consciousness during total anesthesia. The removal of evoked potentials was followed by development of painful reaction. Registration of cerebral evoked potentials helps evaluate the depth of anesthesia and intraoperative memory in patients subjected to total anesthesia.
