During cardiopulmonary bypass (CPB) because of weak arterial pulsation, near-IR spectroscopy (NIRS) is almost the only available method to monitor cerebral oxygenation noninvasively. Our group develops a NIRS oximeter to monitor regional cerebral oxygenation especially its oxygen saturation (rScO2). To achieve optimal coupling between the sensor and human(More)
Cerebral oxygenation especially regional cerebral oxygen saturation (rSO<sub>2</sub>) needs to be monitored to avoid irreversible damages induced by hypoxia. Based on steady-state spatially resolved spectroscopy (SRS), rSO<sub>2</sub> was obtained by the NIRS oximeter developed by our group. The oximeter was calibrated by blood gas analyzer using the liquid(More)
BACKGROUND AND OBJECTIVE Extreme haemodilution occurring with cardiopulmonary bypass imposes a primary risk factor for blood transfusion in small adult cardiac surgical patients. Priming of the cardiopulmonary bypass circuit with patients' own blood [retrograde autologous priming (RAP)] is a technique used to limit haemodilution and reduce transfusion(More)
Although intra-aortic balloon pumping (IABP) has been used widely as a routine cardiac assist device for perioperative support in coronary artery bypass grafting (CABG), the optimal timing for high-risk patients undergoing first-time CABG using IABP is unknown. The purpose of this investigation is to compare preoperative and preventative IABP insertion with(More)
