Peds Hypertension

Hypertensive urgencies and emergencies can be missed in kids when physicians are used to the elevated BP’s of adults with essential hypertension. Hypertension in children is defined relative to the 95th percentile for age & sex. BP > 90th percentile is elevated; Stage 1 hypertension is a BP from the 95th percentile to 95th + 12 mm Hg. Stage 2 hypertension is a BP > the 95th percentile + 12 mm Hg (or > 140/90 for > 13yo). Stage 1 and asymptomatic Stage 2 patients should be referred back to the PMD for confirmation of repeated elevated BPs and outpatient work-up. Hypertensive emergency is a Stage 2 patient with evidence of end-organ damage, e.g. seizure, stroke, altered mental status, papilledema, heart failure, or a BP > the 95th percentile + 30 mm Hg, even if asymptomatic. Charts can be used to determine the 90th and 95th percentile, but a rule of thumb is that 95 + 2 (age in yrs)/50 + 2 (age in yrs) = the 90th percentile, and 115 + 2 (age in yrs)/65 + 2 (age in yrs) = Stage 2 hypertension.
