Abstract 34 patients scheduled for coronary artery bypass graft (CABG) surgery were studied during postoperative period. Right ventricular performance was specially performed with use of cardiac output computer REF-1 Edwards Lab., before Anaesthesia (T1) and at 6 investigation times after surgery during and after mechanical ventilation. The sixth first postoperative hours were marked by a decrease of cardiac index (2.56±0.4 to 2.41±0.4 l·mn-1·m2) and right Ventricular Ejection Fraction (RVEF) (0.48±0.07 to 0.37±0.09). The second period was the weaning period with a further drop of RVEF (0.43±0.1 to 0.36±0.07) without change in cardiac index (2.80±0.5 l·mn-1·m2, suggesting a ventricular postoperative and weaning depression, as previously described for the left ventricle. In addition, postoperative tachycardia (Heart rate=59±9 at T1 to 95±14 at T7) may contribute to myocardial ischemia.
