评估全身麻醉苏醒期患者的意识状态变化，需要运用客观准确的方法。这样可避免苏醒期的不良用药，确保苏醒期患者平稳安全恢复意识，快速去除对患者的不良影响因素，力求减少苏醒期并发症。本文对脑电双频指数等临床常用麻醉深度监测技术用于评估全身麻醉苏醒期患者意识状态改变的研究进展进行简要综述，探究全身麻醉苏醒期患者意识水平的恢复规律，以期降低苏醒期并发症的发生率。“,”It is necessary to use objective and accurate methods to assess the changes of the consciousness of patients emergencing from general anesthesia. In this way, adverse medications during the waking period can be avoided, and it can ensure the stable and safe recovery of consciousness of the patients, quickly remove the adverse factors affecting the patients, and strive to reduce the occurrence of complications during the waking period. This article briefly reviews the research progress of bispectral index and other common clinical anesthesia depth monitoring techniques used to assess the changes of consciousness of patients awakening from general anesthesia, and explores the regular pattern of recovery of consciousness in patients awakening from general anesthesia, in order to reduce complications in the recovery period .
