"Direct current auditory evoked potentials (DC-AEPs)\nare a sensitive indicator of depth of anesthesia in ani-mals. However, they have never been investigated in\nhumans. To assess the potential usefulness of DC-AEPs\nas an indicator of anesthesia in humans, we performed\nan explorative study in which DC-AEPs were recorded\nduring propofol and methohexital anesthesia in hu-mans.\nDC-AEPs were recorded via 22 scalp electrodes\nin 19 volunteers randomly assigned to receive either\npropofol or methohexital. DC-AEPs were evoked by\nbinaurally presented 2-s, 60-dB, 800-Hz tones; meas-urements\nwere taken during awake baseline, anesthesia,\nand emergence. Statistical analysis included analy-sis\nof variance and discriminant analysis of data\nacquired during these three conditions. About 500 ms\nafter stimulus presentation, DC-AEPs could be ob-served.\nThese potentials were present only during base-line\nand emergence¬ónot during anesthesia. Statistically\nsignificant differences were found between\nbaseline and anesthesia and between anesthesia and\nemergence. In conclusion, similar effects, as reported in\nanimal studies of anesthetics on the DC-AEPs, could be\nobserved in anesthetized humans. These results dem-onstrate\nthat DC-AEPs are potentially useful in the assessment\nof cortical function during anesthesia and\nmight qualify the method for monitoring anesthesia in\nhumans."^^ .
