[Problems encountered by the anesthetist-intensive care specialist during aorto-coronary bypass surgery]

The authors studied a series of 288 patients undergoing surgery for aorto-coronary bypass. The anaesthetic protocol and operative protocol are described and particular emphasis is placed upon the aortic clamp time. Mortality and peri-operative complications are then analysed. The treatment of such complications is based essentially upon vasodilators and where necessary intra-aortic counter-pressure balloon device to provide circulatory assistance.
