title: Intravenous valproate associated with significant hypotension in the treatment of status epilepticus.
abstract: Intravenous valproate has been suggested for the treatment of status epilepticus in part because of its relatively good cardiovascular safety profile. We report a case of severe hypotension associated with intravenous valproate used to treat status epilepticus in an 11-year-old girl. Valproate 960 mg (30 mg/kg) was infused over 1 hour. The patient's blood pressure decreased from a baseline of 130/80 mm Hg to 70/55 mm Hg, 39 minutes into the infusion. Although her seizures stopped, her blood pressure fluctuated between 90/60 mm Hg and 60/30 mm Hg over the next several hours, requiring treatment with intravenous fluids and pressor therapy. Endotracheal intubation eventually was performed. Once her blood pressure stabilized, the patient improved clinically. To our knowledge, this is the first report of significant hypotension associated with intravenous valproate in the treatment of status epilepticus in the pediatric population.
