ICU sedation, delirium & recovery
Development of Postanesthesia Care Unit Delirium Is Associated with Differences in Aperiodic and Periodic Alpha Parameters of the Electroencephalogram during Emergence from General Anesthesia: Results from a Prospective Observational Cohort Study
Authors' conclusion
Increased alpha-band power during emergence in patients who did not develop perioperative neurocognitive disorders can be traced back to an increase in oscillatory alpha activity and an overall increase in aperiodic broadband power.
Study context
- Population
- Patients with intraoperative EEG recordings during emergence from GA

- Comparison
- Intraoperative EEG during emergence in patients with vs without perioperative neurocognitive disorders (PACU delirium)
- With perioperative neurocognitive disordersn = 32
- Without perioperative neurocognitive disordersn = 137reference

Primary result
As reported in the abstract
Alpha-band power during emergence, with vs without perioperative neurocognitive disorders
Difference in median absolute alpha-band power, first third of emergence (highest value; AUC 0.74 [0.65; 0.82])
8.53 decibels
Difference in medians, relative alpha-band power, second third of emergence (best relative separation; AUC 0.70 [0.61; 0.79])
