The potential of processed EEG monitoring systems in predicting postoperative cognitive deficits
Authors' conclusion
This study highlights the potential of preoperative pEEG monitoring to identify patients at risk for POD in an elderly surgical population.
Study context
- Population
- Patients undergoing surgery under GA with artifact-free preoperative EEG recordings; median age 71 years80 analysed
- Participants
- 110 patients
- Comparison
- Preoperative processed electroencephalogram (pEEG) indices in patients with vs without postoperative delirium (POD)
- PODn = 24
- Outcome
- Association between preoperative pEEG indices and POD (discrimination by AUC)
Methodological detailsThirty patients excluded due to corrupted baseline data
- Thirty patients excluded due to corrupted baseline data
Performance
As reported in the abstract
Preoperative pEEG indices, POD vs no POD
All indices except spectral edge frequency (SEF) significantly lower at EC baseline in patients with PND; small effect sizes, AUC range
0.62 to 0.65
