Abstract

Compared with the young, the older patient group has increased high-frequency EEG power whilst under volatile general anaesthesia. This increased high-frequency power elevates the spectral entropy values above the recommended range. Thus, aggressive titration of general anaesthesia with volatile agents to achieve entropy values of 40-60 in older patients will commonly result in overdose, as manifest by burst suppression.

摘要

与年轻患者相比，老年患者组在挥发性全身麻醉下高频脑电图功率增加。这种增加的高频功率使频谱熵值升高到推荐范围之上。因此，在老年患者中积极滴定挥发性麻醉剂以达到40 - 60的熵值通常会导致过量，表现为爆发抑制。
