Very high dose phenobarbital for refractory status epilepticus.

BACKGROUND

Refractory status epilepticus (RSE), defined as status epilepticus that fails to respond to first, second and third-line therapy. The RSE is associated with high morbidity and mortality. Treatment guidelines of RSE give a spectrum of options, such as, continuous intravenous (i.v.) midazolam (MDL), or continuous i.v. propofol (PRO) as alternatives to phenobarbital (PB) or continuous i.v. pentobarbital (PTB).

OBJECTIVE

To study the efficacy of very-high-dose phenobarbital (VHDPB) for treatment RSE.

STUDY

DESIGN

Retrospective study

MATERIAL AND METHOD: The authors collected and analyzed data from adult patients who were diagnosed with RSE.

RESULTS

The authors present 10 patients with RSE who were treated with VHDPB. All of them were generalized convulsive status epilepticus (GCSE). Ages ranged from 16-86 years old (mean.: 43 years). PB dosage ranged 40-140 mg/kg/day (mean: 70 mg/kg/day). The duration of status epilepticus (SE) varied widely, ranged 1-44 days (mean: 7 days). PB level ranged 35.29-218.34 ug/mL (mean 88.1 ug/mL). RSE was controlled by VHDPB 70%, 30% were not controlled.

CONCLUSION

VHDPB were considered as alternative treatment for RSE.
