Study of Brainwave Patterns and Risk of Delirium After Surgery in Patients 65 and Older

What this Trial Is About

Researchers are studying whether multiscale entropy analysis of electroencephalogram EEG data can help distinguish between ordinary elderly surgical patients and those who develop postoperative delirium. The study aims to identify postoperative delirium early in patients aged 65 and older undergoing surgery with general anesthesia. The sponsor leading this observational study is Xin Chen. Participants will have their EEG data collected before and during surgery using a device called Neuron-Spectrum-5-1. The study focuses on elderly patients undergoing general anesthesia with specific airway management criteria. There are no drug treatments involved as this is an observational study that monitors brain activity to find patterns linked to delirium. During the study, researchers will observe participants for signs of postoperative delirium within seven days after surgery. They will analyze the EEG data collected and monitor patients closely to evaluate the incidence of delirium. Participation includes EEG recording and standard surgical care, with follow-up assessments to track delirium symptoms during the first week after surgery.
