Table 2.

Inter-individual medians and interquartile ranges and intra-individual ranges of interquartile ranges of each of the 10 patients' individual 20-minute epochs. BIS^®-Dex/Remi = dexmedetomidine and remifentanil; EMG = electromyogram from BIS^® (absolute power in dB (70 to 100 Hz)); IQR = interquartile ranges; Midi/Remi = midazolam and remifentanil; RE = response entropy; SE = state entropy
