[Prevention of complications following aorto-coronary bypass surgery. Proposed solutions].

: In the light of per- and post-operative complications seen in the past, the most suitable anaesthetic protocol for aorto-coronary bypass surgery would appear to be neuroleptanalgesia. This anaesthetic technique appears to decrease the incidence of per- and postoperative hypertensive crises. In addition, the use of cardioplegia also made it possible to decrease the incidence of postoperative complications in a recent group of 39 patients.
