Condition(s) studied

Delirium - Postoperative

Investigational drug(s) / intervention(s)

Collect preoperative and intraoperative electroencephalogram data

Collect preoperative and intraoperative electroencephalogram data: Use Neuron-Spectrum-5-1 to collect preoperative and intraoperative electroencephalogram data.

Study summary

This clinical study aims to investigate whether multiscale entropy analysis of electroencephalogram data can distinguish between ordinary elderly surgical patients and elderly patients with postoperative delirium.This study may help identify postoperative delirium in surgical patients at an early stage.
