BACKGROUND: Remifentanil recently comes to be used for intraoperative analgesia instead of epidural anesthesia in gynecological surgery. It seems to offer the same stability in vital signs, but stress response during remifentanil anesthesia has not been evaluated. Therefore, we compared remifentanil anesthesia with epidural anesthesia regarding stress hormones. METHODS: Fifty-one patients scheduled for surgery were randomized into two groups (epidural group: E and remifentanil group: R). Anesthesia was maintained with propofol and epidural ropivacaine in E, and with propofol and remifentanil in R. Plasma concentrations of adrenaline, noradrenaline, dopamine (DOA), cortisol, adorenocorticotropic hormone (ACTH), and blood glucose were measured at five points during the perioperative period. RESULTS: Adrenaline, noradrenaline and blood glucose were not significantly different between the groups at any point. DOA was significantly higher in R than E at skin closure. Cortisol was significantly higher in R than E at three points during operation. ACTH was significantly higher in E than R at skin closure. CONCLUSIONS: The inhibition of stress hormone secretion during operation was less in R than E. Regarding stress response, total intravenous anesthesia with remifentanil seems to be a proper method, but to have less potency than general anesthesia using epidural block.
