ObjectivesNeuropsychological disorders are some of the most common complications of coronary artery bypass graft (CABG) surgery. The early diagnosis of postoperative brain damage is difficult and mainly based on the observation of specific brain injury markers. The aim of this study was to analyze the effects of volatile anesthesia (VA) on plasma total and ionized arteriovenous magnesium concentrations in the brain circulation (a-vtMg and a-viMg), plasma matrix metalloproteinase-9 (MMP-9), and glial fibrillary acidic protein (GFAP) in adult patients undergoing CABG surgery.DesignAn observational study.SettingThe Department of Cardiac Surgery in a Medical University Hospital.Patients And MethodsStudied parameters were measured during surgery and in the early postoperative period. Patients were assigned to 3 groups: group O, patients who did not receive VA; group ISO, patients who received isoflurane; and group SEV, patients who received sevoflurane.ResultsNinety-two patients were examined. CABG surgery increased MMP-9 and GFAP. The highest MMP-9, GFAP, and the most dramatic disorders in a-vtMg and a-viMg were noted in group O.ConclusionsCardiac surgery increased plasma MMP-9 and GFAP concentrations. Changes in MMP-9, GFAP, and arteriovenous tMg and iMg were significantly higher in group O. Volatile anesthetics, such as ISO or SEV, reduced plasma MMP-9, GFAP concentrations, and disturbances in a-vtMg and a-viMg.Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.
