Lidocaine in refractory status epilepticus: A forgotten drug in the emergency department

Abstract

Generalized tonic-clonic status epilepticus is usually treated with intravenous benzodiazepines and phenytoin. Patients who do not respond to this treatment are generally treated with phenobarbital or general anesthetics both of which may require intubation to maintain respiration. Our experience of four cases with status epilepticus treated with intravenous lidocaine who had failed to respond to diazepam and phenytoin therapy is presented. Two cases responded to a single dose of lidocaine, one required a second dose of lidocaine to control seizures, and the fourth patient failed to respond and died as a result of associated severe head injury. Therefore, there is a need to conduct further studies to establish the efficacy of intravenous lidocaine in the treatment of refractory status epilepticus.
