Refractory convulsive status epilepticus in childhood

Abstract

Refractory convulsive status epilepticus (RCSE) is life-threatening condition, with seizures lasting over one hour and not responding to first and second-line anticonvulsant drug therapy. Any mistreatment or delayed proper treatment significantly increase mortality and neurologic sequelae. First line drugs for convulsion ceasing are benzodiazepines, phenobarbital and phenytoin. In case of refractory status, infusion of midazolam and general anesthesia should be administered. The most important measures of the intensive care are control of vital functions, homeostasis, prevention and therapy for possible brain and systemic complications. Discovery of etiology of status epilepticus is highly important because symptomatic therapy should be administered. Overall mortality rate during RCSE is 13.5%, and is much higher in acute symptomatic group--28.6%. Early sequelae rate is 40.6%, 27.3% and 70% in idiopathic and acute symptomatic groups, respectively.
