Cerebral oxygenation during cardiopulmonary bypass.
Cerebral fractional oxygen extraction (FOE) was monitored in 30 children, using near infrared spectroscopy during cardiopulmonary bypass, to investigate the effect of hypothermia and circulatory arrest. One group of children (n = 15) underwent profound hypothermia with total circulatory arrest (n = 8) or continuous flow (n = 7). Another group (n = 15), of whom only one had circulatory arrest, u...
متن کاملCerebral hyperthermia during cardiopulmonary bypass in adults.
Accepted for publication June 7, 1995 In this report, we document that cerebral hyperthermia occurs regularly during rewarming from hypothermic cardiopulmonary bypass (CPB). These high brain temperatures are not adequately reflected by nasopharyngeal (NP) temperature and may contribute to neurologic morbidity. Stroke and neurocognitive injury remain significant components of perioperative morbi...
متن کاملCerebral oxygenation during cardiopulmonary bypass in children.
OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...
متن کاملCerebral blood flow during cardiopulmonary bypass.
In a study of the cerebral consequences of cardiopulmonary bypass (CPB), we have assessed cerebral blood flow (CBF) by intra-arterial Xenon 133 clearance, utilising a Novocerebrograph 10a, before, during and immediately following CPB. All patients (n = 51), under the care of a single surgical team underwent elective coronary revascularisation using a standardised anaesthetic and surgical protoc...
متن کاملCerebral Artery During Nonpulsatile Hypothermic Cardiopulmonary Bypass
Background and Purpose We evaluated the utility of blood flow velocity measurements by transcranial Doppler ultrasonography as a tool to indirectly measure cerebral perfusion during cardiopulmonary bypass. Methods We simultaneously measured blood flow velocity in the middle cerebral artery and physiological variables in 18 patients undergoing cardiac surgery under hypothermic cardiopulmonary by...
