Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study objectivesIs the newer technique of intra-aortic warm blood cardioplegia superior to the established technique of intermittent aortic cross-clamping for myocardial protection during coronary surgery?
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSurgery: Coronary artery bypass grafting (CABG)
Intervention40 patients undergoing elective CABG will randomly be allocated into two groups of 20 patients each, to receive either intermittent cross clamp with fibrillation (XCF) or intermittent warm blood cardioplegia (WBC). Blood will be taken from in-situ intra-arterial or intravenous cannulae, at the following 12 time points: Following induction of anaesthesia; Following institution of cardiopulmonary bypass, but prior to the application of an aortic cross clamp with resultant myocardial ischaemia; 30,60,90,120 minutes and 4,6,8,12,24,28 hours following final release of the aortic cross clamp. The blood will be centrifuged for serum, which will be stored frozen at -70C until batch analysis. The analysis will be performed blind.
