The second part of review is devoted to definition of the concept of general anesthesia, its effect on implicit memory and consciousness. Some authors believe that consciousness can be preserved during anesthesia as evidenced by implicit memory and “isolated forearm” method. Neurophysiological mechanisms of general anesthesia, features of electroencephalographic patterns depending on anesthetic agent are considered in detail. Analysis of electrophysiological picture suggests that state of general anesthesia corresponds to a controlled drug-induced coma rather physiological sleep. These data allow us to explore new approaches to anesthetic care and develop new types of psychoemotional comfort monitoring as a component of anesthesia.
