ABSTRACT

During the last 25 years, there has been a significant reduction in the mortality and morbidity of the procedures necessitating the use of extracorporeal circulation. As most of the cardiac surgery procedures are now performed with a very low mortality, attention is now focussed on reducing complications and improving quality of life after cardiac surgery. The incidence of psychological disturbances has been reported, in different series, between 10 and 60%. The factors responsible for such a high incidence of psychological changes after extracorporeal circulation are still controversial. Most cardiac surgeons believe the cause to be cerebral hypoperfusion and thereby react by increasing the flow during ECC. On the other hand, neurophysiological experimental data do not confirm this hypothesis. Astrup showed that even at normothermia, cerebral blood flow has to be reduced to less than 20% of the normal value (around 10 ml/100 mg/min.) before cell death related to perfusion can be anticipated [1]. In practice, however, cerebral blood flow during conventional perfusion never falls to such low levels. More... »
