This study introduces a deep learning model to monitor anesthesia depth using electroencephalography (EEG) signals. The model accurately estimates anesthesia depth and predicts transitions to lighter anesthesia, improving patient safety.

Area of Science:

  • Anesthesiology
  • Biomedical Engineering
  • Machine Learning

Background:

  • Electroencephalography (EEG) is crucial for monitoring anesthesia depth during surgery.
  • Existing commercial anesthesia depth indicators are often closed-source and may have delayed responses.
  • There is a need for advanced, open-source methods for real-time anesthesia monitoring.

Purpose of the Study:

  • To develop a multitask deep learning model for continuous Bispectral Index (BIS) estimation.
  • To classify anesthesia states (e.g., deep vs. light anesthesia).
  • To predict impending transitions toward lighter anesthesia states.

Main Methods:

  • Utilized dual-channel EEG signals from the VitalDB dataset (5471 surgical cases).
  • Applied Short-Time Fourier Transform (STFT) to convert EEG signals into time-frequency maps.

  • Employed a ResNet-SE deep learning architecture for feature extraction and prediction.

    • Main Results:

    • Achieved a Mean Absolute Error (MAE) of 3.27 and Root Mean Square Error (RMSE) of 5.48 for anesthesia depth estimation.
    • Obtained an Area Under the Curve (AUC) of 0.99 for light anesthesia classification.
    • Demonstrated the model's capability in assessing anesthesia depth and predicting transitions.

    Conclusions:

    • The proposed multitask deep learning model effectively utilizes EEG signals for anesthesia monitoring.
    • The model provides accurate estimation of anesthesia depth and prediction of transitions to lighter states.
    • This approach offers a potential advancement over current closed-source, delayed monitoring systems.
