Cardiac troponins and volatile anaesthetics in coronary artery bypass graft surgery: A systematic review, meta-analysis and trial sequential analysis.

Reports from animal studies indicate that volatile anaesthetics protect the myocardium against the effects of acute ischaemia-reperfusion injury by reducing infarct size. This cardioprotective effect in the clinical setting of coronary artery bypass graft (CABG) surgery, where the heart is subjected to global ischaemia-reperfusion injury, remains controversial.
