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 emboli detected by transcranial Doppler during cardiopulmonary bypass are not correlated with postoperative cognitive deficits.
BACKGROUND AND PURPOSE High-intensity transient signals (HITS) are the transcranial Doppler representation of both air and solid cerebral emboli. We studied the frequency of HITS associated with different surgical maneuvers during cardiopulmonary bypass for coronary artery bypass graft surgery and their association with postoperative cognitive dysfunction (POCD). METHODS We combined 356 patie...
متن کاملCerebral emboli during cardiopulmonary bypass: effect of perfusionist interventions and aortic cannulas.
Neuropsychological impairment is a very common complication of cardiopulmonary bypass (CPB). The principal cause of postoperative cognitive impairment is thought to be cerebral microemboli during CPB. We recently investigated the effects of perfusionist interventions and aortic cannulation techniques on cerebral emboli production during coronary bypass (CABG) surgery. Patients undergoing isolat...
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...
