Özet
We aimed to determine the effects of remifentanil or fentanyl infusion with midazolam on response to endotracheal intubation, surgical stimulus and intraoperative hemodynamics in coronary artery bypass surgery. Anesthesia was induced with thiopental sodium 0.5-3 mg kg-1 and 2 ?g kg-1 remifentanil (Group R, n=31), or 15 ?g kg-1 fentanyl (Group F, n=29) in 60 cases included into the study. Anesthesia was maintained with 1 ?g kg-1 min-1 remifentanil in group R or 0.15 ?g kg-1 min-1 fentanyl in group F in addition to the midazolam infusion 0.15 mg kg-1 h-1. Mean arterial pressure (MAP), heart rate (HR) were recorded at 1, 3 and 5 min after intubation and surgical stimulus and 5 min intervals during surgery. Also time to intubation and complications were recorded. Heart rate was lower in group R after anesthesia induction. During opioid infusion both MAP and HR decreased more in group R than F. After skin incision, sternotomy and internal mamarian artery dissection MAP and HR were higher in group F than R. Hypertensive response to sternotomy, skin incision, internal mamarian artery dissection was less in group R than group F. Frequency of hypertension and requirement of nitroglycerin were lower in group R than group F during CPB. We concluded that thiopental sodium with remifentanil or fentanyl in anesthesia induction did not prevent the hypertensive response to intubation. However maintenance with remifentanil and midazolam infusion was more effective in preventing surgical stimuli.
