简要总结
Near infra-red spectroscopy (NIRS) was used to measure the tissue perfusion of the cerebral cortex with two noninvasive adhesive patches in recent years. This study is designed to compare the regional tissue perfusion of different body areas in patients receiving coronary artery bypass surgery under general anesthesia. The NIRS data will also be used to compare with other routine physiological monitors in the surgery.
