Cerebral 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 کاملEmbolic activity during in vivo cardiopulmonary bypass.
Neurologic injury after cardiac surgery is principally associated with emboli. Although much work has focused on surgical sources of emboli, less attention has been focused on emboli associated with the heart-lung machine. We tested whether emboli are associated with discrete processes during cardiopulmonary bypass (CPB). One hundred patients undergoing cardiothoracic surgery were enrolled betw...
متن کاملNon-thyroidal illness syndrome and cardiopulmonary bypass in children with congenital heart disease
Abstract Background: The thyroid hormones influence on all metabolic pathways. After heart surgery using cardiopulmonary bypass (CPB), serum T3 decreases and remains low for at least 24 hours. Several studies on pediatric have reported reduction of thyroid hormones after heart surgery. This study aimed to investigate the status of thyroid function tests in children with CPB surgery. Metho...
متن کاملVeno-arterial modified ultrafiltration in children after cardiopulmonary bypass.
A method of performing veno-arterial modified ultrafiltration is described that utilizes conventional blood flow through the aortic and venous cannulae. A dual-pump blood cardioplegia console is adapted to aspirate blood from the cardiopulmonary bypass venous line. The blood is ultrafiltered, sent through the cardioplegia heat exchanger, and returned to the aorta via the cardioplegia needle. Ve...
متن کاملIncreased circulating bradykinin during hypothermia and cardiopulmonary bypass in children.
To determine whether cold could activate the kallikrein-kinin system in vivo as it does in vitro, the circulating systemic concentrations of bradykinin were serially measured in 10 cyildren with congenital diseases of the heart undergoing corrective cardiac surgery. Bradykinin was measured by radioimmunoassay in blood samples obtained before, during and after profound hypothermia (to 18 degrees...
