Electroencephalography (EEG) can predict technical errors in surgery by detecting distinct neural signatures 17 seconds before they occur. This could lead to an early warning system (EWS) to improve surgical training and patient safety.
Area of Science:
- Neuroscience
- Surgical Technology
- Medical Engineering
Background:
- Increasing intraoperative adverse events necessitate improved patient safety measures.
- Existing early warning systems (EWSs) primarily focus on patient deterioration, not surgical performance.
- Prior research explored electroencephalography (EEG) for predicting motor errors in non-surgical contexts.
Purpose of the Study:
- To investigate the potential of EEG in predicting technical errors during surgery.
- To establish a proof-of-concept for an EEG-based system for surgical error detection.
Main Methods:
- A cohort study involving three surgical fellows performing 12 elective laparoscopic general surgeries.
- Simultaneous recording of audiovisual operating room data and surgeon's neural activity (EEG).
- Coding of technical errors and good surgical performance, with neural activity analysis preceding events.
Main Results:
- Distinct neural signatures associated with error monitoring and motor uncertainty were identified.
- These neural signatures were detected significantly earlier (17 seconds) before technical errors occurred.
- No such predictive neural activity was observed prior to epochs of good surgical performance.
Conclusions:
- Specific neural patterns can predict impending technical errors in laparoscopic surgery.
- An EEG-based EWS could enhance surgical training by identifying potential errors before patient harm.
- Further research is needed to validate findings and minimize false alarm rates.
