Abstract
This paper presents research regarding the monitoring of the brain and the adequacy of anesthesia during surgery. Particular variables are derived from EEG and ECG signals and are correlated to anesthetic gas (sevoflurane) concentration, in pediatric anesthesia. The methods used for parameter extraction are based on change detection theory and time-frequency representation. Preliminary results show that the expired anesthetic gas concentration modulates both the heart rate variability and the duration of the burst suppression. Monitors of the central nervous system and autonomic nervous system activities can be expected to be based on these variables.
摘要
本文介绍了关于手术期间大脑监测和麻醉充分性的研究。在小儿麻醉中，特定变量源自脑电图（EEG）和心电图（ECG）信号，并与麻醉气体（七氟烷）浓度相关。用于参数提取的方法基于变化检测理论和时频表示。初步结果表明，呼出的麻醉气体浓度会调节心率变异性和爆发抑制的持续时间。预计基于这些变量可实现对中枢神经系统和自主神经系统活动的监测。
