简要总结
Study Hypothesis Generalized Convulsive Status Epilepticus (GCSE) is a medical emergency associated with an increased morbidity and a prolonged length of hospital stay. Only 50% of patients are discharged from the hospital within the first month after GCSE. Recent Guidelines from Experts highlight the necessity to improve the efficiency of the first line anti-epileptic (AE) therapy.
Intravenous Sodium Valproate (SV) might be an adjuvant AE drug to the recommended first line AEs. Intravenous SV is available, well tolerated and easily injectible but also has pharmacologic properties for reducing the risk of seizures relapses and for being neuroprotective. However, efficacy of intravenous as an adjuvant therapy in GCSE has never been properly assessed.
Primary Purpose The primary purpose is to assess if the association of intravenous Sodium Valproate with the recommended treatment for Generalized Convulsive Status Epilepticus increases to 20 % the number of living patients, discharged from the hospital at day 15.
详细描述
Patient admitted Intensive Care Unit (ICU) for a Generalized Convulsive Status Epilepticus (GCSE) will be randomized if they fulfil the inclusion criteria and after the written informed consent is obtained from the patient's next of kin. In clack of closed relatives, patients could be included according to the French Health Code for Case of medical emergency. In this situation, patient's consent should be then obtained as soon as possible According to randomization arm, patients will be treated either by intravenous sodium valproate (30 mg/kg during 15 min then 1 mg/kg/h during 12 h) or intravenous placebo. All included patients will benefit from first-line anti epileptic drugs and symptomatic medical care, in agreement with the Experts recommendation (RFE 2009).
From day-1 to day-15, level consciousness(Glasgow Coma Scale, Richmond Agitation Sedation Scale), delirium (Confusion Assessment Method For Intensive Care Unit), reoccurrence of seizure, vital signs, organ dysfunction (Simplified Acute Physiology Score II, Sequential Organ Failure) will be daily assessed.
At day 2, the preventive oral anti-epileptic drug will be prescribed by a neurologist, blinded from randomization.
At Day 15 and Day 30, neurological status, cognitive functions (Mini Mental State Examination, Frontal Assessment Battery, Glasgow Outcome Scale), and quality of life (SF36) will be assessed by a neurologist, also not aware of the randomization.
The number of patients alive and discharged from Hospital day 15 15th day will assessed.

入选标准
- •Patient older than
- •Admitted in a participating ICU for generalized convulsive status epilepticus (GCSE) i.e. with persistent or repeated generalized seizures without regaining consciousness over a period of five minutes. provided that the duration of the treatment prior antiepileptic does not exceed:
- •Six hours if GCSE is already controlled at the time of inclusion (= disappearance seizures regardless of the state of consciousness)
- •Twenty-four hours if GCSE persisted or is recurrent.
- •Written informed consent collected from close relation or a family member of the patient. Otherwise, inclusion according to French Health Code in case of medical emergency. In this case, the written informed consent of patient has to be collected as soon as possible then. in absence of a close of patient, the patient may be still included. the consent of the prosecution will be collected
