Design and Development of Multi-modal Intelligent Anesthesia Monitoring System

This project integrates the characteristics of electroencephalo-graph（EEG）, cerebral oxygen, blood pressure, heart rate, etc., based on nonlinear theory and neural oscillation, large sample data and machine learning theory, to develop a multi-modal monitoring system suitable for domestic patients, taking into account changes in sedation, analgesia, cerebral hemodynamics and other factors, regardless of patient age and type of general anesthesia drugs.

Treatment and study plan

Multi-modal Intelligent Anesthesia Monitoring System

Diagnostic Test

To evaluate the sensitivity and specificity of self-developed anesthesia monitoring systems in diagnosing the depth of anesthesia (too deep or too shallow)

Primary outcomes

the depth of anesthesia (too deep or too shallow)

Time frame: During general anesthesia

PRST score system, combined with BIS index for comprehensive judgment

Secondary outcomes

EEG characteristics of loss of consciousness induced by different general anesthesia drugs

Time frame: During general anesthesia

Spectral Analysis，Connectivity Analysis，Brain Networks Analysis
Characteristics of perioperative neurovascular coupling

Time frame: Perioperative

EEG power and entropy indexes are extracted by moving window method as new time series, and a new time series consistent with NIRS is constructed. The entropy and power of different frequency bands after resampling were used as the indexes of neural activity, and ΔHbO and ΔHb were selected as the indexes of hemodynamic activity. The neurovascular coupling was evaluated by calculating the coherence of neural activity and hemodynamic activity.
