Age-dependent EEG Characteristics During Desflurane Anesthesia From Adults to Elderlies

This study is a prospective cohort study that records bilateral frontal EEG data from patients undergoing elective non-cardiac or non-neurosurgical surgeries and divides them into different age groups based on age. All patients received maintenance of general anesthesia with desflurane, and the periodic and aperiodic components, permutation cross mutual information (PCMI), and phase lag entropy (PLE) of EEG data were analyzed under different states of wakefulness, general anesthesia, and recovery. Professional correlation analysis methods were used to analyze the EEG spectrum.
