Background: Phase lag entropy (PLE) is a novel anesthetic depth indicator that uses four-channel\nelectroencephalography (EEG) to measure the temporal pattern diversity in the phase relationship of frequency\nsignals in the brain. The purpose of the study was to evaluate the anesthetic depth monitoring using PLE and to\nevaluate the correlation between PLE and bispectral index (BIS) values during propofol anesthesia.\nMethods: In thirty-five adult patients undergoing elective surgery, anesthesia was induced with propofol using\ntarget-controlled infusion (the Schneider model). We recorded the PLE value, raw EEG, BIS value, and hemodynamic\ndata when the target effect-site concentration (Ce) of propofol reached 2, 3, 4, 5, and 6..................
