BACKGROUND: Whether delayed @entity2806 (DCI) mediates the relationship between Hunt and Hess grade and outcomes after @entity510 remains unknown. OBJECTIVES: To investigate the relationship between cerebral perfusion pressure, DCI, Hunt and Hess grade, and outcomes after @entity510 . METHODS: DCI was defined as @entity16 due to @entity1503 . Relationships between minimum cerebral perfusion pressure and onset and occurrence of DCI were tested by using logistic regression and the accelerated failure time model. The mediation effect of DCI on relationships between Hunt and Hess grade and outcomes was tested by using the bootstrap confidence interval. Outcomes at 3 and 12 months included mortality and neuropsychological, functional, and physical outcomes. RESULTS: DCI occurred in 211 @entity1 (42%). About one-third of the @entity1 had poor functional outcome at 3 (32%) and 12 (30%) months. Impaired neuropsychological outcome was observed in 33% of @entity1 at 3 months and 17% at 12 months. For every increase of 10 mm Hg in cerebral perfusion pressure, odds for DCI increased by 2.78 (95% CI, 2.00-3.87). High perfusion pressure was associated with earlier onset of DCI (P < .001). CONCLUSIONS: DCI does not mediate the relationship of Hunt and Hess grade to functional outcome or @entity204 . The relationship between cerebral perfusion pressure and DCI was most likely due to induced @entity101 and hypervolemia. Clinical guidelines may need to include limits for induced @entity101 .
