Cerebral death occurs prior to cessation of cardiac activity. The mechanism of action of pentobarbital in protecting the brain from ischemia and intracranial pressure is not completely understood; however, it is related to pentobarbital's anesthetic action (produced by sufficiently high dosage) and possibly to the … The immediate effect is the unconsciousness of deep anaesthesia followed by rapid death in overdose.
