World's Largest Resource for Cardiovascular Perfusion
Through the whole surgical period, ScO2 correlated strongly with mean blood pressure regardless of the physiological type. the physiological parameters affecting ScO2 and SrO2 were rather different. Accordingly, the significance of monitoring of cerebral and somatic tissue oxygen saturation in pediatric cardiac surgery should be further evaluated.
HAR is proposed as a new approach to increase the safety of the CPB. Its overall benefits should be properly assessed and validated by current and further studies.
