Abstract

Patients with coronary artery disease have a high risk of adverse cardiac outcome during and after surgery. Thoracic epidural anesthesia (TEA) aims at a more specific reversible blockade of cardiac sympathetic efferents and provides effective intra- and postoperative analgesia. In the TEA group heart rate (HR) was low (12,6%, p <0,05) compared with the group of traditional anesthesia during the construction of the anastomoses for any of the three surgical setting. Stroke index was higher (17,4%) in TEA group that specifies to more optimum work of heart at which the greatest duration of diastole is kept for improvement of a coronary blood flow. Myocardial oxygen consumption decreases due to decreased heart rate and low peripheral vascular resistance (11,8%) and pulmonary vascular resistance (26,3%) in comparison with control group. Conclusion: TEA provides better hemodynamic control and analgesia compared with traditional anesthesia.
