麻醉是现代医学临床手术中必不可少的关键环节,具有较高的风险.研究证明,术中麻醉深度监测能够有效地降低麻醉剂使用量并减少恢复时间,从而降低麻醉过程中出现并发症的危险.对于麻醉深度监测方法的研究已经成为国际研究热点.主要介绍了麻醉深度监测的多种方法,包括脑电双频指数、听觉诱发电位、熵指数以及心率变异性；着重介绍了这些方法的原理、优、缺点及相互之间的关系,并且详细阐述了心率变异性与麻醉深度监测的关系及该方法的历史和现状；重点分析了心率变异性时域和频域分析方法,为研究以该方法为指导的麻醉深度监测技术奠定了理论基础.

Anesthesia is the most crucial part of clinical surgery in modern medicine,and it is highly risked due to complications of general anesthesia.Researches have proved that intraoperation monitoring depth of anesthesia efficiently reduced the dosage of anesthetics and led to earlier recovery,so that the risk of anesthesia has been minimized.Currently,the research on depth of anesthesia monitoring methods has become an international hotspot.This paper reviews the methods for monitoring depth of anesthesia,including bispectral index,auditory evoked potential,Entropy and heart rate variability,and highlights advantages,disadvantages of these methods and the relationship between these methods.This paper also introduces the relationship between heart rate variability and the depth of anesthesia monitoring,the method for analyzing heart rate variability in both time domain and frequency domain,which laid a theoretical foundation for the research on monitoring depth of anesthesia.
