BackgroundOur goal was to perform a systematic review of the literature on the use of modern inhalational anesthetic agents for refractory status epilepticus and their impact on seizure control.MethodsAll articles from MEDLINE, BIOSIS, EMBASE, Global Health, HealthStar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform (inception to March 2014), reference lists of relevant articles, and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and Grading of Recommendation Assessment Development and Education methodology by two independent reviewers.ResultsOverall, 19 studies were identified, with 16 manuscripts and 3 meeting abstracts. A total of 46 patients were treated. Adult (n=28) and pediatric patients (n=18) displayed 92.9% and 94.4% seizure control with treatment, respectively. Isoflurane was used in the majority of cases. Hypotension was the only complication described.ConclusionsOxford level 4, Grading of Recommendation Assessment Development and Education D evidence exists to support the use of isoflurane in refractory status epilepticus to obtain burst suppression. Insufficient data exist to comment on the efficacy of desflurane and xenon at this time.
