Cardiac arrest & resuscitation
EEG in a four-electrode frontotemporal montage reliably predicts outcome after cardiac arrest
Authors' conclusion
In this cohort, EEG background patterns determined in a four-electrode frontotemporal montage predict both poor and good outcome after CA with similar reliability.
Study context
- Population
- Patients after cardiac arrest with EEG at 12 and/or 24 h220 EEG epochs
- Participants
- 153 patients
- Comparison
- 4-electrode frontotemporal EEG montage vs standard 9-electrode montage
- Outcome
- Agreement of EEG background classification (Cohen's kappa) and sensitivity/specificity for prediction of poor (cerebral performance categories (CPC) 3-5) and good (CPC 1-2) neurological outcome
- Follow-up
- 24 h after cardiac arrest (prognostication)
