Sodium valproate compared to phenytoin in treatment of status epilepticus
چکیده
Background: Status epilepticus (SE) is a neurological emergency which can be life-threatening. Several medical regimens are used in order to control it. In this study, we intended to evaluate the clinical efficacy and tolerability of sodium valproate and intravenous phenytoin (IV PHT) in the control of SE. Methods: One hundred and ten consecutive patients suffering from benzodiazepine refractory SE who were referred to the emergency ward from March 2014 to March 2015 were randomly divided into two groups. The first group received intravenous sodium valproate, 30mg/kg as loading dose and then 4-8mg/kg every 8 hr as maintenance regimen. The second group received IV PHT 20mg/kg as loading dose and then 1.5mg/kg for 8 hr as maintenance therapy. All patients were monitored for vital signs every 2 hr up to 12 hr. The patients were also followed up for 7 days regarding drug response and adverse effects. Results: The administration of sodium valproate and phenytoin respectively resulted in seizure control in 43 (78.18%) and 39 (70.90%) of the patients within 7 days of drug administration (p=.428). Seven-day mortality rate was similar in both groups (12.73% vs. 12.73%; p=.612). There was no significant difference in adverse effects between two groups. Conclusion: Sodium valproate is preferred to IV PHT for treatment and control of SE due to its higher tolerability and lower hemodynamic instability.
