Key result
Electroencephalography monitoring during the perioperative period provides valuable information for assessing depth of anesthesia, preventing neurocognitive disorders, and prognosticating clinical outcomes.
Why the study?
EEG monitoring has become technically feasible in daily clinical anesthesia practice and represents an important frontier in perioperative monitoring and treatment.
EEG monitoring is a valuable tool for assessing depth of anesthesia, recognizing brain states, preventing perioperative neurocognitive disorders, detecting cerebral ischemia, and prognosticating clinical outcomes in perioperative and ICU settings.
May support EEG for perioperative neurocognitive protection; leaves open confirmation via randomized trials.
Electroencephalography (EEG) monitoring has become technically feasible in daily clinical anesthesia practice. EEG is a sensitive method for detecting neurophysiological changes in the brain and represents an important frontier in the monitoring and treatment of patients in the perioperative period. In this review, we briefly introduce the essential principles of EEG. We review EEG application during anesthesia practice in the operating room, including the use of processed EEG in depth of anesthesia assessment, raw EEG monitoring in recognizing brain states under different anesthetic agents, the use of EEG in the prevention of perioperative neurocognitive disorders and detection of cerebral ischemia. We then discuss EEG utilization in the intensive care units, including the use of EEG in sedative level titration and prognostication of clinical outcomes. Existing literature provides insight into both the advances and challenges of the clinical applications of EEG. Future study is clearly needed to elucidate the precise EEG features that can reliably optimize perioperative care for individual patients.
