Résumé
Objective To investigate the effects of sevoflurane combined anesthesia on the early cognitive function of the elderly patients.Methods 120 patients underwent laparoscopic surgery in our hospital from August 2014 to August 2016 were selected and randomly divided into two groups:sevoflurane group 60 cases, sevoflurane anesthesia during operation and propofol anesthesia 60 cases, propofol anesthesia during operation.MMSE was used to detect the cognitive function at one day before operation, one day, three days and seven days after surgery respectively.The blood samples were taken from the patients of the two groups at the time of one day before operation, one hour after operation and one day after operation, the levels of serum TNF-αand IL-6 were measured by enzyme-linked immunosorbent assay ( ELISA ) . The recovery time and adverse reactions were observed after operation.Results The average recovery time was (18.94 ±3.32) min in the propofol group and (10.62 ±2.31) min in the sevoflurane group, the sevoflurane group was better than the propofol group, the difference was statistically significant (P<0.05).The scores of MMSE were significantly lower in the sevoflurane group one day after operation than those in the one day before operation, the difference was statistically significant (P<0.05).The scores returned to the preoperative level three days and seven days after operation.In the propofol group, the MMSE score was significantly lower at one day after operation than that before operation, the difference was statistically significant (P<0.05), but increased three days after operation but did not reach the preoperative level, and sevoflurane group, the difference was statistically significant.After treatment, the levels of TNF-and IL-6 in serum of two groups increased, the level of TNF-αand IL-6 in the propofol group one hour after operation and one day after operation were significantly higher than those in the sevoflurane group, the difference between the two groups was statistically significant ( P <0.05 ).Conclusion The sevoflurane compound anesthesia in patients after surgery, the recovery of cognitive ability faster, fewer side effects in patients.
