[Coronary artery bypass grafting by warm blood cardioplegia and normothermic cardiopulmonary bypass]

Abstract

Warm blood cardioplegia and normothermic cardiopulmonary bypass (CPB) have been used in coronary artery bypass grafting (CABG). The method of myocardial protection was intermittent combined antegrade and retrograde warm blood cardioplegia with terminal warm blood cardioplegia. We performed elective CABG in 30 patients above the age of 70 years (elderly group). These patients were compared with 30 patients below 70 years who underwent elective CABG (young group). No significant differences were observed about the preoperative data between two groups. No significant differences were obtained in the postoperative cardiac function, cerebral or renal complication between two groups. Warm blood cardioplegia and normothermic CPB were not associated with adverse effects on postoperative recovery in elderly as well as young patients. We may conclude that warm blood cardioplegia with normothermic CPB is a safe procedure for CABG in elderly as well as young patients.
