Abstract:
Objective To study the cerebral distribution of inhalational anesthetics and their effect on memory under inhalational combined with intravenous anesthesia. Methods 45 patients, undergoing elective abdominal and limb operations, were randomly divided into: isoflurane group (n=15), sevoflurane group (n=15), and desoflurane group (n=15). The narcosis was maintained by inhalational anesthetics combined with intravenous anesthetics. EEG non-linear topographic map of approximate entropy was recorded. The perioperative memory of the patients was estimated by process dissociation procedure (PDP) after patients awoke. Results Comparing with pre-operative examination results, there was distinct declination of intra-operation explicit and implicit memory in all three groups, and the difference was statistically siqnificant (P
