Cerebral Oxygenation During Cardiopulmonary Bypass
Despite the low mortality of coronary bypass surgery (CABG) there is still a high incidence of neuropsychological defects at 1 and 6 months after surgery(l,2). The introduction of alpha stat C02 regulation for hypothermic cardiopulmonary bypass (CPB) preserves auto regulation of cerebral blood flow if mean arterial blood is maintained above 50 mm Hg(3), and it was thought that cerebral perfusion was likely to be adequate for the reduced cerebral oxygen requirements during hypothermia.
