AbstractThe study included 44 patients who were divided into 3 groups according to the type of anesthesia. In group 1 patients (n = 15), initial anesthesia was accomplished by inhaled sevoflurane and intravenous fentanyl (2.5-3.5 microg/kg); basal anesthesia was performed with sevoflurane. In Group 2, midazolam, 0.1-0.15 mg/kg, fentanyl, 5.2 +/- 0.01 vg/kg, and ketamine, 0.85 +/- 0.13 mg/kg were given for induction. Basic anesthesia was carried out, by administering fentanyl in a dose of 4.71 +/- 0.4 microg/kg/hour, halothane, 0.5-1.5 ob %. In Group 3, midazolam, 1.2 +/- 0.01 mg/kg) and fentanyl, 7.8 +/- 0.6 microg/kg) were used to induce anesthesia. Basic anesthesia was effected with fentanyl, 5.31 +/- 0.5 microg/kg/hour, ketamine, and diprivan. Anesthetic management using halogen-containing inhalational anesthetics at coronary bypass surgery in patients at high anesthetic risk was ascertained to cause a significant reduction in the degree of manifestations of oxidative stress and facilitated a better intraoperative period. Sevorane was found to have the most significant effect on oxidative stress.
