Refractory status epilepticus: Electroconvulsive therapy as a possible therapeutic strategy

Refractory status epilepticus (SE) is a current daily therapeutic challenge. Electroconvulsive therapy (ECT), which is frequently used to treat psychiatric disorders, is known to raise the seizure threshold. As such, ECT could be of major interest in refractory SE. In this paper, we provide a brief overview of ECT in refractory SE. Although no placebo-controlled or open-label study has been published on the efficacy or safety of ECT in refractory SE, eight case reports have been identified. SE cessation was obtained in 80% of cases, and complete recovery was achieved in 27% of patients. Despite the heterogeneity of the ECT parameters used in these articles, we identified some common features that may be recommended for the use of ECT in refractory SE. ECT might be a viable therapeutic strategy for the most resistant and severe cases of SE, particularly after the failure of two inductions of anesthetic coma. This potential indication highlights the urgent need for clinical trials that assess the usefulness of ECT in refractory SE.
