[Possible causes and prevention ways of short-term postoperative mental disorders after regional and general anesthesia].

: The authors have studied the incidence and possible causes of short-term postoperative mental disorders (STPMD) (in different types of intraoperative protection) that are determined as a nonspecific central nervous system (CNS) lesion characterized by concomitant disorders of consciousness, recognition, memory, emotions, and psychomotor functions, as well as sleep-wakening cycles. Intraanesthetic awakening has been established to play a leading role in the development of STPMD. Under general anesthesia, the incidence of the latter is not higher than that under regional anesthesia, although the causes of STP-MD are likely to be different in either case. And, finally, CNS function monitoring is seemingly considered to be a compulsory component of intraoperative control of a patient's condition during general anesthesia. In addition, it may prevent intraanesthetic awakening episodes and the development of postoperative cognitive disorders in many respects.
