Adjunctive enteral phenobarbital for adult status epilepticus: A brief report

Abstract

Background: Status epilepticus (SE) is a neurological emergency condition. Intravenous phenobarbital (PB) is recommended for refractory SE treatment. However, intravenous PB is unavailable in Thailand. Enteral PB has been shown to be effective in SE children. Methods: In adult SE patients, the efficacy of enteral PB as an adjunctive therapy has been reported. This is a case series of adult SE patients who were treated with enteral PB at Khon Kaen University Hospital, Thailand. The clinical features and clinical outcomes are reported. Results: There were six patients; five patients had convulsive SE, and one patient had nonconvulsive SE. All patients received PB enterally, at dosages of 900 mg initially and repeated doses of 900 mg as needed. This was gradually reduced to a maintenance dosage of 180 mg/day. Three out of six patients were completely controlled, whereas the other three patients were partially controlled. Three out of six patients were seizure-free after the initial loading dose of PB. No adverse effects were found in this study. Conclusion: In adult patients, enteral PB may be effective as an add-on for refractory SE therapy. © 2013 Tiamkao et al.
