Description of intervention(s) / exposure
A comparison of 2 different anaesthetic agents (propofol and sevoflurane) and their affect on cardioprotection in non insulin diabetic patients undergoing coronary artery bypass graft surgery requiring cardiopulmonary bypass. 2 groups of 20 patients each will be randomised to receive either propofol or sevoflurane to maintain general anaesthesia whilst on cardiopulmonary bypass. Anaesthesia leading up to bypass will be the same in each group. At 15 minutes post separation from bypass, both groups will receive sevoflurane anaesthesia alone. Otherwise, management will be as per normal for coronary artery bypass patients.
