Does raw electroencephalogram-guided anesthesia administration reduce postoperative complications in elderly patients undergoing major abdominal surgery?
rEEG-guided anesthesia does not reduce broad postoperative complications in elderly patients undergoing major abdominal surgery, but it reduces intraoperative burst suppression and over-deep sedation.
In elderly patients undergoing major abdominal surgery, rEEG-guided anesthesia did not reduce the incidence of postoperative respiratory, circulatory, neurological and gastrointestinal complications. rEEG-guided anesthesia management reduced the duration of intraoperative BS in patients and the duration of over-deep sedation in patients with lower frontal alpha waves under anesthesia, and there was a strong association between lower frontal alpha power under anesthesia and the development of POD. rEEG-guided anesthesia may improve the prognosis of patients with vulnerable brains by improving the early identification of frail elderly patients and providing them with a more effective individualized anesthetic managements.
