NCT06317025

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • the depth of anesthesia (too deep or too shallow)

    PRST score system, combined with BIS index for comprehensive judgment

    During general anesthesia

Secondary Outcomes (2)

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

    During general anesthesia

  • Characteristics of perioperative neurovascular coupling

    Perioperative

Study Arms (1)

General anaesthetic patient

Monitoring depth of anaesthesia using PRST (P:pressure, T:tear,R:rate, S:sweat)score developed by Evans and bispectral index

Diagnostic Test: Multi-modal Intelligent Anesthesia Monitoring System

Interventions

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

General anaesthetic patient
