RESUMO
Objective To explore the efficiency and safety of sodium valproate intravenous therapy on refractory status epilepsy(RSE)by diazepam in Chinese adult.Methods Twenty-five patients of RSE,consecutively admitted to West China Hospital of Sichuan University from September 1999 to May 2007,received intravenous administration of sodium valproate after being refractory to intravenous diazepam and intramuscular phenobarbitone.The efficiency and side effect of sodium valproate were then evaluated.There were ten males and fifteen females with mean age of fifty-five years.The symptoms of status epilepticus(SE)included generalized tonic-clonic status epilepticus(GTCS)(14 cases),complex partial status epilepticus(CPS)(7 cases),simple partial status epilepticus(SPS)(2 cases)and myoclonic status epielepticus(MS)(2 cases).The primary diseases prior to SE were viral encephalitis(13 cases),withdrawal of antiepilepsy drug(AEDs)(5 cases),cerebral trauma and brain surgery(3 cases),cerebral infarction(2 cases),intoxication(1 case)and cerebral palsy(1 case).Among them nine patients had a history of epilepsy.Results Of all the 25 cases of RSE,twenty-two were controlled with sodium valproate within one hour,and consciousness recovered within next one hour.No significant changes were found in blood pressure,heart rate,respiratory rate and cardiac rhythm,and no encephalopathy occurred.On the other hand,the other three cases who failed to be controlled,frequency and duration of seizure were redured.Conclusions Although intravenous sodium valproate has not been approved to be the drug of first choice for SE therapy,but it is non-sedative anti-convulsion drug that can be safely used to stop different kinds of diazepam resistant SE efficiently without obvious side effect.In addition,a quick recovery of patients' consciousness may be expected within an hour afte RSE being controlled.
