Effect of cardiopulmonary bypass on cortical cerebral oxygenation during coronary artery bypass grafting.
OBJECTIVE To investigate the changes in cerebral oxygenation during coronary artery bypass grafting (CABG) with normothermic cardiopulmonary bypass (CPB) using near infrared spectroscopy. METHODS Measurement of cerebral cortical oxygenation changes included concentration of deoxygenated haemoglobin [HHb], oxygenated haemoglobin [O(2)Hb], changes in the redox status of the cytochrome c oxidase...
متن کاملCerebral 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 کاملAtrial fibrillation after coronary artery bypass grafting without cardiopulmonary bypass.
OBJECTIVE Atrial fibrillation is the most common complication after heart surgery. It rarely has a fatal outcome but causes patient instability, prolongs hospital stay, or even is the reason for perioperative infarction. Although conventional coronary artery bypass grafting (CABG) with cardiopulmonary bypass has excellent short-term and long-term results, the number of coronary operations on a ...
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 کاملConsequences of coronary artery bypass grafting in smokers and addicts
Introduction: The most common cardiac disease is coronary artery disease (CAD) in the world. Coronary artery bypass grafting (CABG) is implemented through two standard surgical techniques, namely off-pump beating-heart CABG (OPCABG) and on-pump CABG (ONCABG). The CABG results in various levels of morbidity, especially in smokers and addicts, who have a lower pain threshold. Regarding this, the ...
