The role of the standard 20 minute EEG recording in the @entity772 XXXX .

@entity1 @entity410 @entity772 @entity1167 @entity159
@entity410 and @entity159 ( @entity159 ) are believed common in @entity772 @entity1 and are suggested to worsen outcome. The purpose of this study was to prospectively evaluate outcome in @entity1 in critical care units in whom @entity159 was suspected to determine how often evidence of @entity410 activity existed based on an isolated standard 20 minute electroencephalogram (EEG) and to determine what clinical factors predicted outcome. We prospectively reviewed EEGs and clinical charts of @entity1 admitted to a critical care unit at a tertiary care center who were suspected to have non- @entity410 @entity410 . Outcomes were correlated with EEG findings, clinical factors, and acute therapies using univariate and multivariate logistic analyses. Of 189 @entity1 , complete information was available in 169. Eighty-one (47.9%) @entity1 died, 67 (39.6%) were discharged home, and 21 (12.4%) were discharged to long-term care. Four @entity1 had @entity410 , two of whom had no clinical manifestations (i.e. non- @entity410 ). On univariate analysis, increased age, an admitting diagnosis of @entity1167 , a Glasgow @entity772 Scale (GCS) score8, and burst suppression were correlated significantly with poor outcome. A past history of @entity410 and unequivocal tonic-clonic @entity410 were correlated significantly with a better outcome. On multivariate analysis, increased age, @entity1167 , and a GCS score8 were associated with increased mortality (p<0.05). Clinical factors, including age, underlying etiology and GCS score are the most important predicators of outcome in @entity772 . A standard 20 minute EEG did not correlate with a high detection rate of @entity410 activity. Furthermore, EEG patterns and treatment with anticonvulsant medications did not correlate with outcome.
