Quantitative Validation of a Simplified 4-Lead Electroencephalogram Montage for Neuromonitoring in Post–Cardiac Surgery Intensive Care Unit Patients
Authors' conclusion
A computationally derived 4-electrode montage (F3, F4, F7, and F8) demonstrates close agreement with the 16-electrode reference for global qEEG trend parameters in deeply sedated post-cardiac surgery patients.
Study context
- Population
- Patients in intensive care unit (ICU) ≥24 h after cardiac surgery with CPB, deeply sedated (RASS −4) during EEG recording
- Participants
- 26 patients
- Comparison
- Reduced-lead EEG configurations vs 16-lead reference EEG
- Outcome
- Agreement with reference (qEEG parameters)
