Purpose: To explore outcome differences between propofol and midazolam (MDL
) therapy for refractory status epilepticus (RSE).
Methods: Retrospective chart review of consecutive patients treated for RSE
between 1995 and 1999.
Results: We found 14 patients treated primarily with propofol and six with
MDL. Propofol and MDL therapy achieved 64 and 67% complete clinical seizure
suppression, and 78 and 67% electrographic seizure suppression, respective
ly. Overall mortality, although not statistically significant, was higher w
ith propofol (57%) than with MDL (17%) (p = 0.16). Subgroup mortality data
in propofol and MDL patients based on APACHE II (Acute Physiology and Chron
ic Health Evaluation) score did not show statistically significant differen
ces except for propofol-treated patients with APACHE II score greater than
or equal to 20, who had a higher mortality (p = 0.05). Reclassifying the on
e patient treated with both agents to the MDL group eliminated this statist
ically significant difference (p = 0.22).
Conclusions: In our small sample of RSE patients, propofol and MDL did not
differ in clinical and electrographic seizure control. Seizure control and
overall survival rates, with the goal of electrographic seizure elimination
or burst suppression rather than latter alone. were similar to previous re
ports. In RSE patients with APACHE II score greater than or equal to 20, su
rvival with MDL may be better than with propofol. A large multicenter, pros
pective, randomized comparison is needed to clarify these data. If comparab
le efficacy of these agents in seizure control is borne out. tolerance with
regard to hemodynamic compromise, complications, and mortality may dictate
the choice of RSE agents.
