In the therapeutic suppression of status epilepticus, propofol and other agents typically produce a burst-suppression pattern on the way to producing more extensive, global cerebral suppression. The two primary components of consciousness are awareness and arousal with the determination of consciousness being made by the examination of the patient’s response to stimuli.
