麻醉深度监测与自主神经系统

背景目前临床上应用的麻醉深度监测方法多基于对脑电图（electroencephalogram，EEG）的分析，主要反映全身麻醉的意识状态，对临床麻醉中的自主神经系统活动反映不敏感。目的综述心率变异性（heartrate variability，HRV）分析对自主神经系统的评估在麻醉深度监测中的价值。内容总结近年来有关麻醉深度监测方法的研究进展，现有麻醉深度监测方法的局限性及对自主神经活动性的评价在麻醉深度监测中的应用。趋向HRV分析用于自主神经系统功能评估将使麻醉深度的判断更趋完善。

Anesthesia depth monitoring and autonomic nervous system

Background Up to now, the methods of monitoring the depth of anesthesia have been mainly based on electroencephalogram (EEG) analysis, which mainly reflects the state of consciousness, and is not sensitive to autonomic nervous system activity in clinical anesthesia. Objective To review the value of heart rate variability (HRV) analysis for assessment of the autonomic nervous system in the depth of anesthesia monitoring. Content To summarize the progress of the depth of anesthesia monitoring methods in recent years,the limitation of the existing depth of anesthesia monitoring methods and application of evaluation of autonomic nervous activity in the depth of anesthesia monitoring. Trend Application of HRV analysis in evaluation of autonomic nervous system function will make the depth of anesthesia monitoring more perfect.
