Status epilepticus in children and adults.
Status epilepticus (SE) is defined as a continuous seizure that lasts more than 30 minutes or as serial seizures in which the patient does not regain a premorbid level of consciousness. This condition exists primarily in two forms: convulsive (focal or generalized) and nonconvulsive (absence or partial complex) SE. Protracted or serial convulsive seizures represent a medical emergency with a current mortality rate of 10%. As in any urgent or life-threatening situation, the initial treatment is directed at support and maintenance of vital functions. Specific anticonvulsant management is usually begun with intravenous lorazepam. This benzodiazepine is replacing diazepam in many medical centers because it has a longer duration of action and causes less respiratory depression. Concurrent intravenous loading with phenytoin is usually necessary for sustained control of seizures. Phenobarbital may be required as a third drug if seizures persist or recur. In cases of refractory status epilepticus, barbiturate coma, continuous anticonvulsant intravenous infusion, or general anesthesia may be necessary.
