- Preoperative cognitive dysfunction in older cardiac surgery patients was studied to understand its link to intraoperative EEG parameters and cerebral hypoxia.
- The study found that impaired preoperative cognition (MoCA score <26) was associated with significantly lower spectral edge frequency (SEF) values, indicating increased sensitivity to isoflurane anesthesia.
- No significant association was observed between preoperative cognitive dysfunction and burst suppression duration, cerebral desaturation events, or combined EEG and cerebral oximetry abnormalities.
- The results suggest that SEF may serve as a marker for cognitive vulnerabilities during surgery, requiring further validation for clinical use in optimizing perioperative care.
