Background: New antiepileptic drugs (AEDs) have provided alternatives to traditional treatment paradigms for status epilepticus (SE).
Methods: To determine current treatment preferences for generalized convulsive status epilepticus (GCSE), we surveyed 106 members of the Critical Care or Epilepsy sections of the American Academy of Neurology.
Results: Most respondents initially treat patients with intravenous (IV) lorazepam (76%), followed by phenytoin or fosphenytoin (95%) if first-line therapy fails. Preferences for GCSE refractory to two AEDs (RSE) varied: 43% would give phenobarbital, 19% would give one of three continuous-infusion (cIV) AEDs (pentobarbital, midazolam, propofol), and 16% would give IV valproic acid. About half indicated "burst suppression" (56%) and half indicated "elimination of seizures" (41%) as the titration goal for cIV-AED therapy. About half (42%) would add a new cIV-AED, and the other half (41%) would not add another agent to treat electrographic SE refractory to four AEDs.
Discussion: In accordance with published trials and general guidelines, neurologists most often use lorazepam followed by phenytoin or fosphenytoin as first-line and second-line therapies for GCSE. There is no consensus for third-line or fourth-line treatment for RSE. The treatment of RSE needs to be studied in a large, prospective, randomized, multicenter trial.
