Predictors of Low Risk for Delirium during Anesthesia Emergence
Authors' conclusion
This study developed an easily applicable exploratory method to analyze a single frontal EEG channel and to identify patterns specific for patients at low risk for delirium.
Study context
- Population
- Patients undergoing surgery with GA maintained with propofol, sevoflurane, or desflurane (median age, 61 yr [49, 73])
- Participants
- 169 patients
- Comparison
- Positive slope vs Negative slope
- Primary endpoint
- Delirium (screen positive in the PACU)
Methodological detailsexploratory EEG predictive analysis, post hoc analysis, single frontal EEG channel, linear regression of EEG power slope during emergence
