ABSTRACT:
The apparatus has: electrodes (E.sub.1 to E.sub.6) which are to be attached to a predetermined region of a living body; a skin potential measuring unit (1) which detects the skin potential from the electrodes; a judging unit (3) which detects and stores the skin potential before administration of an anesthetic agent, which detects and stores that after administration of the anesthetic agent, which sets a threshold to be an arbitrary level, on the basis of a change from the stored skin potential before administration of the anesthetic agent to the stored skin potential after administration of the anesthetic agent, and which compares the time-varying skin potential with the threshold, thereby judging the depth of anesthesia; and an alarm unit (6) which raises an alarm in accordance with instructions from the judging unit.
