The data presented for the second case involving the 9-mo-old patient receiving inhaled anesthesia. The raw spectrogram for the period of the procedure involving multiple changes in the patient’s brain and behavioral states (A). Signatures of awakening, profound unconsciousness, and adequate unconsciousness are all present and easily identifiable despite the patient’s young age. Changes in the EEG spectrogram preceded changes in patient behavior, while changes in heart rate (B) and blood pressure (C) both followed the awakening event (timepoint 1, red line). The blue line (timepoint 2) represents the timepoint when the patient stops moving. D, An identical pattern of brain and behavioral activity has been previously reported by Cornelissen et al.33 EEG indicates electroencephalogram.
