Burst sedation
WebBIS values of 65–85 are recommended for sedation, whereas values of 40–60 are recommended for general anaesthesia. At BIS values of less than 40, cortical suppression becomes discernible in raw EEG as a burst suppression pattern (Fig. 10.40). 4. BIS measures the state of the brain, not the concentration of a particular drug. WebPropofol doses for induction were 1.8 +/- 0.1 mg/kg (mean +/- standard error); for maintenance, doses were 86 +/- 3.5 micrograms/kg per min; and for burst suppression doses were 500 micrograms/kg per min. After clipping, the propofol dose rate was reduced to allow early recovery and neurological examination in the operating room.
