Key Points

  • The aim is to evaluate how phase-specific EEG monitoring can predict postoperative delirium (POD) during aortic surgery.
  • Conducted phase-specific EEG monitoring during aortic arch surgery.
  • Analyzed predictive factors occurring in different intraoperative phases.
  • Assessed the sensitivity of EEG to physiological changes.
  • Phase-specific EEG predictions were reliable for identifying POD.
  • Predictive factors changed depending on the surgical phase.
  • Suggests potential for improved perioperative management and risk stratification.

Abstract

Phase-specific EEG monitoring reliably predicted POD during aortic arch surgery. Predictive factors varied across intraoperative phases, underscoring the dynamic sensitivity of EEG to physiological changes. Comprehensive, phase-specific EEG assessment may improve risk stratification and perioperative management, though large prospective studies are needed to confirm these findings.
