- which results in cerebral anoxia, edema and long term damage
what is status epileptics
continuous seizure or a series of seizures from which a patient never recovers consciousness between attacks
status epileptics
- depletes the energy stores, increases O2 consumption, increases metabolic demands =
cerebral anoxia and edema
is status epileptics a medical emergency
yes
what drugs do we use to halt seizure activity
benzos
- lorazepam
- valium
what drugs do we use to maintain seizure free state
phenytoin
phenobarbital
