title: Effects of sevoflurane vs. propofol on mitochondrial functional activity after ischemia-reperfusion injury and the influence on clinical parameters in patients undergoing CABG surgery with cardiopulmonary bypass.
abstract: The aim of the study was to evaluate the effects of sevoflurane and propofol on the activity of mitochondrial function related to ischemia-reperfusion injury, myocardial damage biomarkers release and clinical parameters in the postoperative period. Seventy-two patients scheduled for elective coronary artery bypass graft surgery with cardiopulmonary bypass were randomized into two groups: 36 patients received sevoflurane during anesthesia (Group S) and 36 patients received propofol (Group P). To investigate the functional activity of mitochondria, we used skinned fibers prepared from biopsies of right atrial tissue before cardioplegia and after the aorta cross-clamp removal (within 10-15 minutes after reperfusion). Patients' clinical data (length of stay in ICU, hemodynamic parameters, duration of mechanical ventilation (MV) and the amount of lactate and troponin I in the blood serum) were evaluated postoperatively. The results showed that, before cardioplegia and after reperfusion, there was no significant difference in the mitochondrial routine and State 3 respiration rates between the groups. The effect of cytochrome c was higher in Group P. Troponin I concentration at the 12(th) hour after the surgery was 2.2 ± 0.8 ng/mL in Group S and 3.5 ± 1.1 ng/mL in Group P (p<0.001). There were no significant differences in the duration of mechanical ventilation, hemodynamic parameters and length of stay in the ICU between the groups. We conclude that sevoflurane slightly protects the mitochondrial outer membrane from ischemia-reperfusion injury and the loss of cytochrome c, yet has the similar effect on clinical parameters in the postoperative period when compared to propofol.
