Near-infrared spectroscopy (NIRS) is a noninvasive technology that continuously monitors regional tissue oxygenation. Originally used for assessment of oxygen saturation of the brain, its use has now been expanded to evaluation of oxygenation of tissues other than the brain. There is also growing evidence for the larger applicability of NIRS as an estimate of systemic venous saturation in correspondence with the adequacy of the circulatory status. New and promising advances may further this technology to become part of our standard armamentarium, in order to optimize patient care in daily anesthesia practice. The present paper briefly reviews the basic principles of operation, the inherent limitations of the technology and the clinical data that have been acquired with NIRS monitoring in the broad field of acute clinical medicine.
近红外光谱技术（NIRS）是一种可连续监测局部组织氧合情况的无创技术。它最初用于评估脑氧饱和度，如今其应用范围已扩展至对脑以外其他组织的氧合评估。越来越多的证据表明，NIRS作为循环状态是否充足的指标，在评估全身静脉饱和度方面具有更广泛的适用性。新的且有前景的进展可能会推动该技术成为我们标准医疗设备的一部分，以便在日常麻醉实践中优化患者护理。本文简要回顾了其基本工作原理、该技术的固有局限性以及在广泛的急性临床医学领域通过NIRS监测所获得的临床数据。
