Intravenous valproate treatment of generalized nonconvulsive status epilepticus.
Status Epilepticus (SE) is a medical emergency warranting prompt treatment with rapidly-acting antiepileptic drugs. For immediate effect, benzodiazepines are the drugs of choice, but may result in morbidity due to respiratory suppression and hypotension. Nonconvulsive status epilepticus usually does not have significant neurological sequelae, and there is little evidence that generalized nonconvulsive status epilepticus (GNSE) causes lasting neurologic deficits. The risk versus benefit of potentially morbid medications must, therefore, be weighed against the "adverse effects" of GNSE. A patient with frequent episodes of GNSE lasting 4-48 hours had previously been treated with benzodiazepines, but required admission for consequent somnolence. Following intravenous valproate given during EEG monitoring, GNSE broke after 30 minutes. The confused patient returned to a normal cognition and returned home without sequelae. Intravenous valproate may provide an effective treatment alternative to benzodiazepines in GNSE without their associated morbidity.
