Brief summary
This study aims to investigate the efficacy of add-on exogenous ketone esters for the treatment of children with refractory generalized convulsive status epilepticus
Detailed description
Generalized convulsive status epilepticus (GCSE) is a common neurological emergency in children with significant morbidity and mortality. Benzodiazepines (Bzs) are the initial anti-seizure medications (ASMs) for children with GCSE, but nearly a third of cases are not controlled by (Bzs). Moreover, about 40% of cases not responding to BZs are not controlled by second-line ASMs. Ketogenic diet (KD) has been classically used for treating children with drug resistant epilepsy. Recently, KD has been used for refractory and super refractory status epilepticus. However, KD takes time to achieve ketosis and may be practically challenging in emergency situations and critically ill patients. Exogenous ketone esters (EKE) could be a more convenient and rapid way to achieve ketosis in acute settings.
Interventions
500 mg/kg over 5 min administered by nasogastric tube, followed after 1 hr by repeated hourly doses of 125 mg/kg for 8 hrs.

Study design
Intervention model description
Eligible children will be randomized into two equal-sized groups. Study group: will receive exogenous ketone esters plus standard of care. Control group: will receive only standard of care.
