  Purpose

The purpose of this study is to determine whether propofol or barbiturates should be preferred in the treatment of status epilepticus (continuous seizure activity) refractory to 2 standard antiepileptic agents.

Primary Outcome Measures:
  • Refractory Status Epilepticus Controlled With First Course of Study Drug [ Time Frame: after return of continuous EEG activity (typically after 36 hours - 5 days) ] [ Designated as safety issue: No ]
    Control of status epilepticus refractory to benzodiazepines and a first antiepileptic drug after administration of the study drug; dichotomous assessment (yes/no)


Secondary Outcome Measures:
  • Clinical Outcome at Day 21 [ Time Frame: 21 days ] [ Designated as safety issue: No ]
    Return to baseline clinical conditions (i.e.: no new handicap, no death)

  • Patients With Infectious Complications Requiring Specific Treatment [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
  • Patients With Hypotension Requiring Specific Treatment [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
  • Patients With Propofol Infusion Syndrome [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
    Propofol infusion syndrome (PRIS) is a severe metabolic alteration with elevation of lactate, CK, and triglycerides.

  • Intubation Time in Survivors [ Time Frame: Up to 3 months ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: 1
propofol, 2mg/kg as bolus, then titrated up to EEG burst-suppression as a continuous infusion; no maximum doses defined
Drug: propofol
liquid, mg/kg.h, titrated after EEG
Other Name: Disoprivan
Active Comparator: 2
thiopental/pentobarbital, 2mg/kg as bolus, then titrated up to EEG burst-suppression as a continuous infusion; no maximum doses defined
Drug: thiopental/pentobarbital
liquid, mg/kg.h, titrated after EEG
Other Name: Pentotal /Thiopentone

Detailed Description:

Refractory status epilepticus (SE) develops in 31%-44% of patients with SE, with a mortality of 16%-23%. Coma induction is advocated for its management. Propofol and barbiturates are the most used agents, but no comparative study has been performed. In consideration of the uncertainty regarding the relative effectiveness, despite several retrospective data, a prospective investigation is needed.

The objective is to assess the effectiveness (SE control, adverse events) of a first course of propofol versus barbiturates in the treatment of refractory SE, in adults with refractory SE not due to cerebral anoxia.

Comparison: Coma induction with standardized doses of propofol or barbiturates titrated towards burst-suppression on EEG, then assessment of the proportion of patients achieving a control of SE.
