[Intraoperative management of emergency coronary artery bypass grafting].
Intraoperative hemodynamics during emergency coronary artery bypass grafting (CABG) for acute evolving myocardial infarction (26 cases) were measured and compared with those during elective CABG (39 cases). Before cardiopulmonary bypass period, it was strongly suggested that the cardiac function of emergency cases was worse than that of elective cases because of the following 5 factors; (1) hypotension, (2) tachycardia, (3) low stroke volume index, (4) pulmonary congestion and (5) metabolic acidosis. Proper usage of inotropic supports, vasodilators, anesthetic agents, and control of acidosis and hypoxemia seemed to be more important in emergency CABG. These prudent intraoperative hemodynamic managements have played important roles in the progress of the operative outcome of emergency CABG.
