Objective: In this study, the effects of fentanyl and remifentanyl on the surgical stress response in patients undergoing cholecystectomy operation were compared.

Study design: 35 patients with ASA I-II physical status undergoing cholecystectomy were included in this study. The same general anaesthesia was given to patients which were double blind randomly divided into two groups. Group F (n=18) had Imcglkg fentanyl and until 20 seconds before the end of surgery lmcg/kg/h fentanyl was infused. Group R (n=17) had lmcg/kg remifentanil and until the end of surgery 0. 25mcg/kglmin remifentanyl was infused. MABP, HR values and blood cortisol, insuline, glucose, ACTH and GH levels were measured in four periods: 1. before the induction of anaesthesia, 2. before the surgical incision, 3. 10 minutes after the incision and 4. 20 minutes after extubation.

Results: During 2. and 3. period MABP, HR values were lower in Group R compared with Group F (p<0.05) and blood cortisol level was lower during 2. and 3. period in comparison with the first period. (p<0.001) There was no difference in the other stress parameters between the 2 groups

Conclusion: During cholecystectomy, remifentanyl provided more stable hemodynamics compared with fentanyl. There was no difference in stress response between the 2 groups and neither remifentanyl nor fentanyl was able to abolish stress response.

Keywords: cholecystectomy, remifentanyl, fentanyl, surgical stress response.
