摘要
背景近红外线光谱（near-infraredspectroscopy，NIRS）监测局部脑氧饱和度（cerebraloxygensaturation，rSO2）是一种新型的局部脑氧供需平衡的监测方法，具有灵敏、快速、实时、持续、无创等特点。通过经皮测定rSO2，了解脑局部皮层的灌流和氧供需情况。目的综述NIRS技术监测rSO2及其临床应用，为临床工作提供参考。内容从NIRS技术监测rSO2的基本原理、临床应用及影响因素3方面进行阐述。趋向NIRS技术多用于监测脑血管外科及心脏外科围术期的脑氧供需平衡状态和脑灌注变化情况，预防围术期脑缺血及脑过度灌注的发生，在无创监测颅内压及评估脑血管痉挛的临床治疗等方面具有广阔的应用前景。
Background Near infrared spectroscopy （NIRS） is a new method for monitoring regional cerebral oxygen supply and demand balance with sensitive, fast, and real-time, continuous and noninvasive features. Some detail information on the regional cerebral cortex blood perfusion and oxygen supply and demand balance can be obtained by NIRS percutaneous detecting regional cerebral oxygen saturation （rSO2）. Objective The aim of this review is to outline the near infrared spectroscopy for monitoring regional cerebral oxygen saturation and provide practical reference data for clinical work. Content This review includes three aspects： the principle of NIRS monitoring rS02, its clinical application and affected factors. Trend NIRS monitoring rSO2 is mainly applied to monitor oxygen supply and demand balance and the changes of cerebral perfusion to prevent cerebral ischemia and hyperperfusion, and which has vast applied foreground on noninvasive monitoring intracranial pressure and evaluating the clinical treatment of cerebrovasospasm so on.
