Abstract

Objective The monitoring of anesthetic depth based on electroencephalogram derivation is not currently adjusted for age. Here we analyze the influence of age factors on electroencephalogram characteristics. Methods Frontal electroencephalogram recordings were obtained from 80 adults during routine clinical anesthesia. The characteristics of electroencephalogram with age and anesthesia were observed during four kinds of anesthesia. Results The slow wave power, δ power, Bispectral Index (BIS) and approximate entropy can be used to distinguish different states of anesthesia (P < 0.05). In the deep and very deep anesthesia states, δ power decreased with age (P < 0.0001). In the very deep anesthesia state, θ power decreased with age (P < 0.05). In the deep and very deep anesthesia states, α power decreased with age (P = 0.0002). In the light and deep anesthesia states, β power decreased with age (P = 0.003). In the deep anesthesia state, γ power decreased with age (P = 0.002). In the very deep anesthesia state, permutation entropy increased significantly with age (P = 0.0001). In the very deep anesthesia state, BIS value increased with age (P = 0.006). The slow wave power, approximate entropy, and sample entropy did not show age-dependent changes. Conclusions The influence of age should be considered when using BIS and δ power to monitor the depth of anesthesia, while the influence of age should not be considered when using slow wave power and approximate entropy to monitor the depth of anesthesia.

不同麻醉深度下与年龄相关的脑电图特征
目的 基于脑电图推导的麻醉深度监测目前尚未根据年龄进行调整。在此,我们分析了年龄因素对脑电图特征的影响。方法 对 80 名成人进行常规临床麻醉时的额部脑电图进行记录。观察四种麻醉过程中脑电特征与年龄和麻醉的关系。结果 慢波功率、δ功率、双谱指数(BIS)和近似熵可用于区分不同的麻醉状态(P < 0.05)。在深度和极深度麻醉状态下,δ功率随着年龄的增长而下降(P < 0.0001)。在极深麻醉状态下,θ 功率随年龄增长而下降(P < 0.05)。在深度和极深度麻醉状态下,α功率随年龄的增长而下降(P = 0.0002)。在轻度和深度麻醉状态下,β 功率随年龄的增长而下降(P = 0.003)。在深度麻醉状态下,γ 功率随年龄的增长而下降(P = 0.002)。在极深麻醉状态下,置换熵随年龄的增长而显著增加(P = 0.0001)。在极深麻醉状态下,BIS 值随着年龄的增长而增加(P = 0.006)。慢波功率、近似熵和样本熵没有出现与年龄相关的变化。结论 使用 BIS 和 δ 功率监测麻醉深度时应考虑年龄的影响,而使用慢波功率和近似熵监测麻醉深度时不应考虑年龄的影响。
