Mean Arterial Pressure and Discharge Outcomes in Severe Pediatric Traumatic Brain Injury.

In children with severe TBI, a single MAP < 10th percentile during the first 12 h after Pediatric Intensive Care Unit admission was associated with poor discharge outcome. Lowest MAP percentile during the first 12 h was moderately predictive of poor discharge outcome. Lowest MAP percentile was more strongly associated with outcome than lowest SBP percentile but had slightly lower predictive ability than SBP.
