背景脑氧饱和度监测在多学科围手术期应用越来越广泛，通过监测脑氧饱和度及时发现脑缺血/缺氧及脑灌注变化情况。
目的综述脑氧饱和度监测3种方法的临床应用，为临床工作提供参考。
内容从颈静脉球部氧饱和度（jugular venous oxygen saturation，SvjO 2）监测、脑组织氧分压（brain tissue oxygen tension，PtiO 2）监测、近红外光谱（near-infrared spectroscopy，NIRS）监测3种监测技术的原理、临床应用、不足及发展趋势等方面进行阐述。
趋向PtiO 2监测、NIRS监测等技术已广泛应用于心脏外科、神经外科围手术期管理及ICU，监测脑氧代谢情况及脑灌注，对于预防脑缺血和过度脑灌注有重要指导意义，具有良好的临床应用前景。
BackgroundMaintenance of normal cerebral oxygen saturation and metabolism is an essential element in perioperative anesthetic management. Several methods have been applied in the perioperative period to monitor cerebral oxygen saturation in order to timely detect ischemia, hypoxia, and abnormal perfusion in the brain.
ObjectiveTo review three methods forcerebral oxygenation monitoring to provide technical information for perioperative application.
ContentThree procedures have been commonly used in neurosurgery, cardiovascular surgery, and ICU to achieve surveillance of cerebral oxygen saturation levels. They arejugular vein oxygen saturation monitoring, brain tissue oxygen tension monitoring, and near-infrared spectroscopy. This review provides sophisticated information about these methods, including their principles, clinical application, advantages, and disadvantages.
TrendBrain tissue oxygen tension monitoring and near-infrared spectroscopy monitoring are helpful to prevent cerebral ischemia and inadequate cerebral perfusion in cardiac surgery, neurosurgery, and ICU.
