The Perioperative Frontal Relative Ratio of the Alpha Power of Electroencephalography for Predicting Postoperative Delirium After Highly Invasive Surgery: A Prospective Observational Study
Authors' conclusion
Intraoperative frontal relative ratios of the α-power of EEG were associated with POD in patients who underwent radical cancer surgery.
Study context
- Population
- Patients undergoing radical cancer surgery with reconstruction for esophageal, oral floor or pharyngeal cancer under TIVA80 analysed
- Participants
- 84 patients
- Exposure
- Patients with vs without postoperative delirium (POD)
- Outcome
- Relative ratio of EEG α-power and inflammatory markers in patients with vs without POD

Main finding
As reported in the abstract
Relative ratio of α-power at baseline · baseline
POD
0.18
± 0.08
non-POD
0.28
± 0.11
P < 0.001
Observational data: associations, not effects.
Further findings
| Outcome | POD | non-POD | P value |
|---|---|---|---|
| Preoperative NLR | 2.88 ± 1.04 | 2.22 ± 1.00 | P < 0.001 |
Relative ratio of α-power during surgery · 3-h, 6-h, 9-h
- Time-dependent decline during surgery in both groups
- Significant differences between POD and non-POD at baseline, 3-h, 6-h and 9-h
Other intraoperative inflammatory markers
- Comparable between the groups
