Abstract
To identify predictors of neurological complications in the hospital period after coronary artery bypass grafting (CABG), 92 patients with coronary heart disease aged 70 years and over were analyzed. Intraoperative monitoring of cerebral oxygenation (rSO2, %) was carried out. At the stage of induction anesthesia, the average level of rSO2 for left and right hemispheres was 64-65% without significant changes during the operation. A decrease in rSO2 during cardiopulmonary bypass (CPB) was associated with increased risk of neurological complications. The risk of neurological complications increase 7-fold and 9-fold with a decrease in rSO2 by 20% or more during CPB relative to baseline for left and right hemispheres, respectively. A history of two or more myocardial infarctions increases 3-fold the risk of neurological complications after CABG.
