title: [Effect of propofol and isoflurane on surgical stress response and postoperative cognitive function in elderly patients].
abstract: OBJECTIVE
  To investigate the effect of propofol and isoflurane on surgical stress response and postoperative cognitive function in elderly patients.
  
  
  METHODS
  Sixty elderly patients scheduled for elective upper abdominal surgery with general anesthesia were randomized equally into propofol group and isoflurane group. The surgical stress response, postoperative Mini-mental State Examination (MMSE) and the rate of postoperative cognitive dysfunction (POCD) were compared between the two groups.
  
  
  RESULTS
  The surgical stress response in propofol group was relatively stable. Compared with isoflurane group, the patients in propofol group showed significantly faster recovery of the MMSE scores with also lower rate of POCD.
  
  
  CONCLUSIONS
  Compared with isoflurane, propofol intravenous anesthesia is associated with rapid recovery of the cognitive function, stable surgical stress response and reduced adverse effects in elderly patients.
