BackgroundThe relationship between systolic blood pressure and outcome in children after severe traumatic brain injury (TBI) is unclear. We examined the relationship between age-appropriate systolic blood pressure (AASBP) percentile and outcome after severe pediatric TBI.MethodsWe examined the association between AASBP percentiles and outcome in 172 children younger than 14 years of age with a Glasgow Coma Scale score < 9. Outcome was evaluated using discharge Glasgow Outcome Scale score. Poor outcome was defined as a Glasgow Outcome Scale score < 4.ResultsPoor outcome was associated with AASBP < 75th percentile (odds ratio, 4.2; 95% confidence interval, 2.1-8.3). Patients with systolic blood pressure (SBP) > or = 90 mm Hg and AASBP < 75th percentile had a higher odds for poor outcome compared with patients with SBP > or = 90 mm Hg and AASBP > or = 75th percentile (odds ratio, 3.5; 95% confidence interval, 1.7-7.3). CONCLUSION AASBP < 75th percentile was associated with poor outcome after severe pediatric TBI, even when SBP was > or = 90 mm Hg.
