Acute Management of Status Epilepticus

Initial Assessment and Treatment

The American College of Emergency Physicians recommends assessing circulation, airway, and breathing (CAB) and providing airway protection as needed, as well as administering high-flow oxygen to prevent hypoxia, which can worsen seizures, in patients with status epilepticus 3, 1
Establishing IV access for medication administration is crucial in the initial assessment and treatment of status epilepticus, according to the American Academy of Neurology 1, 3
Checking blood glucose level immediately to rule out hypoglycemia as a cause of status epilepticus is recommended by the American Diabetes Association 4, 3
Obtaining vital signs, including temperature, to identify potential infectious causes of status epilepticus is essential, as stated by the Infectious Diseases Society of America 1, 3

The American Academy of Neurology recommends administering lorazepam 0.1 mg/kg IV (maximum 4 mg) at 2 mg/min as a first-line treatment for status epilepticus, which may be repeated once after 5-10 minutes if seizures continue 1
If seizures persist after benzodiazepines, the American Epilepsy Society suggests administering one of the following second-line treatments: fosphenytoin 20 mg/kg PE IV at 150 mg/min, valproate 30 mg/kg IV at 6 mg/kg/hour, or levetiracetam 40 mg/kg IV (maximum 2,500 mg) 4, 1

The Neurocritical Care Society recommends transferring patients with refractory status epilepticus to the ICU and considering the administration of phenobarbital 10-20 mg/kg IV (maximum 1,000 mg) at 50-100 mg/min or propofol 1-2 mg/kg IV bolus, followed by 2-10 mg/kg/hour infusion 3, 1
Initiating continuous EEG monitoring to detect ongoing seizure activity is crucial in the management of refractory status epilepticus, as stated by the American Clinical Neurophysiology Society 3

The American Academy of Neurology recommends obtaining laboratory studies, including electrolytes, complete blood count, toxicology screen, and anticonvulsant drug levels, to identify metabolic abnormalities and underlying causes of status epilepticus 4, 1
Considering neuroimaging (CT or MRI) once the patient is stabilized is essential to identify potential structural causes of status epilepticus, according to the American College of Radiology 5, 1

The American Epilepsy Society suggests continuing maintenance doses of antiseizure medications, such as levetiracetam 15-30 mg/kg IV every 12 hours, phenobarbital 1-3 mg/kg IV every 12 hours, or valproate or phenytoin at appropriate maintenance doses, after seizure cessation 3, 1
Monitoring for adverse effects of medications, including respiratory depression, hypotension, and cardiac arrhythmias, is crucial, as stated by the American Heart Association 4, 1
