Myocardial damage prevented by volatile anesthetics: a multicenter randomized controlled study.

Objective: The purpose of this study was to evaluate the effects of volatile anesthesia versus total intravenous anesthesia on cardiac troponin release in off-pump coronary artery bypass grafting (OPCAB).

Design: The authors performed a multicenter randomized controlled study to compare cardiac troponin release in patients receiving either volatile anesthetics or total intravenous anesthesia for cardiac surgery on the beating heart, which is an excellent model of human myocardial ischemia.

Setting: Three university hospitals.

Off-pump coronary artery bypass grafting reduces postoperative neurologic complications.

Objective: Complications occurring after coronary artery bypass graft (CABG) surgery, particularly neurologic damage, have been mainly correlated with the use of cardiopulmonary bypass (CPB). The aim of this work was to compare postoperative outcomes of patients undergoing CABG surgery, with or without the use of CPB, focusing on neurologic events.

Design: Observational study.

Cardiac biomarker release after CABG with different surgical techniques.

Objective: To investigate the release of cardiac biomarkers (troponin I and CK-MB) in patients undergoing coronary artery bypass graft (CABG) with or without cardiopulmonary bypass (CPB).

Design: Prospective study.

Setting: University tertiary hospital.
