Abstract：In the cardiac intensive care unit,the accurate assessment of tissue oxygenation holds paramount importance in mitigating morbidity and mortality rates.Currently,clinical practice predominantly relies on invasive techniques,such as mixed venous oxygen saturation,cardiac output and blood gas analysis,for evaluating patient oxygenation.However,these traditional monitoring methods are frequently hindered by various interfering factors,resulting in limited accuracy.The advent of near-infrared spectroscopy(NIRS)technology offers a new solution.As a continuous and noninvasive monitoring modality,NIRS accurately assesses the oxygen saturation of local tissues,providing a fresh perspective in cardiac intensive care.This technology has found widespread application in monitoring cerebral oxygen saturation during cardiac surgery,while also demonstrating successful implementation in renal and skeletal muscle oxygen saturation monitoring.This article aims to comprehensively review the utilization of NIRS in the postoperative monitoring of oxygen saturation in the brain,kidney and skeletal muscle following cardiac surgery.By enabling early condition assessment,NIRS technology serves as a robust guidance tool to assist the doctors in precisely evaluating patient oxygenation status and devising more effective treatment strategies.
