Anesthesia record. EEG waves and frequency analysis at each point. Anesthetic record is shown in (a). The BIS value remained from 30 to 40 throughout the perioperative period. Anesthesia was induced by intravenously injecting ketamine (20 mg) and rocuronium bromide (40 mg) at that period. The EEG at lower frequency below 8 Hz was dominant (b). The EEG pattern was continuous throughout the surgery (c, d). Abbreviations: HR, heart rate; sBP, systolic blood pressure; dBP, diastolic blood pressure; BIS, bispectral index; SEF95 (Hz), 95% spectral edge frequency; SR (%), suppression ratio
