Status epilepticus is defined as more than 30 minutes of (1) continuous seizure activity or (2) two or more sequential seizures with out full recovery of consciouslness between seizures. Seizures may be convulsive or non-convulsive. The longer the seizure continues, the greater the likelihood of an adverse outcome such as neurologic damage or death. (Return to the index to view a document on the management of epilepsy.)
Incidence : 18-50 cases per 100,000 persons/year Approx. 260,000 new/recurrent cases of status epilepticus per year.
Epilepsy affects 1:200 individuals in the general population and 1:4 individuals with mental retardation. It is estimated that up to 20% of people with epilepsy experience status epilepticus. About 75% of patients who experience status epilepticus are under the age of 5. Status epilepticus is less frequent in individuals whose epilepsy is well-controlled.
Note: These considerations are in addition to the normal medical care provided to an individual without status epilepticus.
Note: Emergency services should be contacted if there is any concern for the well-being of the patient. Because no one can accurately predict whether a seizure will last twenty to thirty minutes or more (which is a requirement for the diagnosis of status epilepticus), and because appropriate emergency care may not be accessible due to distance or time, caregivers should be prepared to administer rectal diazepam (Diastat). Diastat is appropriate for epileptic patients ages 2 and over who have a seizure lasting longer than five minutes.
0 to 5 minutes
6 to 10 minutes
Note: The noted times may not be applicable in the emergency room setting. Many tests and procedures may occur concurrently, such as IV access, medication administration, etc.
31 to 45 minutes
After seizure stops
