[Anesthesia for aorto-coronary bypass]
Abstract:
The authors have analysed a series of 357 patients undergoing aortocoronary bypass. The onset of complications was studied in relation to the past history, the anaesthetic protocol, the period of extra-corporeal circulation and the type of myocardial protection. Complications consisted of acute hypertensive episodes, arrhythmias, peroperative myocardial ischemia and myocardial infarction. The degree of beta-blocker therapy and above all its continuation up to the time of operation would seem to be an important factor in effective myocardial protection.
