Continuing Medical Education

promoCard_v5 Clinical Electroencephalography for Anesthesiologists is based on a two-lecture series developed by Patrick L. Purdon, Ph.D. and Emery N. Brown, M.D., Ph.D. at Massachusetts General Hospital. In these two online modules, anesthesiologists will learn how to read the electroencephalogram (EEG) to monitor brain states during general anesthesia and sedation.

This series is built around the belief that the EEG should be transparent, highly accessible, physiologically-principled, and seamlessly compatible with current clinical practice.

We introduce a tool – the spectrogram – to make anesthesia-induced EEG oscillations easier to read and interpret. With this new approach, anesthesiologists will see that different drugs have unique “EEG signatures” related to their specific brain mechanisms.

With practice, these signatures become easy to recognize, and provide an instantaneous readout of a patient’s brain state under anesthesia.

Part I: Background & Basic Signatures

  • Interpret EEG patterns using the spectrogram
  • Recognize EEG signatures of propofol, ether-derived anesthetics, dexmedetomidine, ketamine, and nitrous oxide
  • Learn how anesthetic mechanisms relate to EEG signatures

Part II: Intraoperative Management

  • Recognize EEG signatures of commonly used anesthetic drug combinations
  • Understand how EEG signatures vary in pediatric and elderly patients
