Abstract:
Objective To study the brain distribution of propofol and its effect on memory under intravenous combined anesthesia. Methods 20 patients undergoing elective abdominal abdomen and limb operations were randomly divided into propofol 8mg?kg -1 ?h -1 group (n=10) and 10mg?kg -1 ?h -1 group (n=10). The perioperative EEG non-linear topographic map of approximate entropy was recorded. The perioperative patients' memory was estimated by process dissociation procedure (PDP) after operation. Results Comparing with pre-operative examination results, the intra-operation explicit and implicit memory markedly declined in both propofol 8mg?kg -1 ?h -1 group and 10mg?kg -1 ?h -1 group. There was statistically significant difference between the pre-operative and intra-operative explicit and implicit memory (P
