Objectives

Narrative objectives1

The purpose of this study is to verify that the incidence of delirium after desflurane anesthesia is lower in elderly patients who are managed at an appropriate depth of anesthesia based on anesthesia EEG. In this study, we will (1) record and analyze EEG during desflurane anesthesia using a general-purpose anesthesia depth monitor and a digital EEG monitor, and (2) examine the optimal desflurane concentration according to age based on the anesthesia EEG. The achievement of optimal-anesthesia depth control based on EEG analysis will improve the neurological prognosis of elderly patients and contribute to the prevention of postoperative delirium.

Registration in the UMIN clinical trial registration system
Recruitment of adult patients scheduled for abdominal surgery of 120 minutes or longer at Tohoku University Hospital who require general anesthesia or general anesthesia with epidural anesthesia (50 patients in total)
A. What to do in the clinic
Before induction of general anesthesia, a general-purpose depth-of-anesthesia monitor (BIS) is applied, and EEG recording and depth-of-anesthesia monitoring are started.
After securing the airway, start general anesthesia with desflurane and remifentanil. The concentration of desflurane is gradually increased until a group suppression wave (EEG indicating deep anesthesia) is observed. The biometric monitor and EEG data are automatically transferred and stored on the server in the operating room.
B. What will be done in the study (additions to medical practice)
Before induction of general anesthesia, install an additional digital EEG monitor and start recording. Titration of desflurane concentration should not be rapid, but 1% every 10 minutes. The biometric monitor and EEG data obtained during general anesthesia should be stored on a personal computer.
C. Analysis of EEG data (for research purposes)
