Abstract: 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.
