The Fourth Task Force Report on Pediatric High Blood Pressure
6 Questions • Does the child really have high blood pressure? • Do I have time to ask any more questions? • Why does the child have high blood pressure? • Does the child have other risk factors? • What has high blood pressure already done to the child's body? • What should we do about it?

Blood Pressure Measurement Technology is in the Dark Ages. Confirm all blood pressure readings before acting.
It’s a Pain in the A** to Detect HTN Equipment is inherently flawed, hard to find Or gives inaccurate readings if not used right.
It’s a Pain in the A** to Detect HTN Spurious elevations are common
It’s a Pain in the A** to Detect HTN Not everyone has a BP reading.
It’s a Pain in the A** to Detect HTN Mild Hypertension takes weeks to confirm

Recognizing or ruling out a hypertensive emergency is the 1st order of business in any hypertension evaluation.

Is this an Emergency? Hypertensive Emergency Elevated Blood Pressure with symptoms of end-organ damage Hypertensive Urgency A high BP that makes you uncomfortable
Hypertensive Emergencies • Drop the Blood Pressure no more than 10% • Use short acting IV medications • IV Labetolol • IV Hydralazine • IV Nicardipine drip • Start small and then escalate your dose • Get the patient to a PICU
Chris Chest Pain and a splitting headache Labetolol and hydralazine given on the floor – no effect. Nicardipine drip in PICU. BP 150s/80s by noon.

Other Causes of Pediatric Hypertension that you still think about • Inpatients • Increased ICP • Pain • Iatrogenic steroid-induced • Uncommon outpatient causes • Endocrine causes (Cushing, Pheo) • Pre-eclampsia
Rule of Thumb #1 The Younger the Patient with Hypertension, the More Likely you’ll find a Cause
Rule of Thumb #2 • The Higher the Blood Pressure, • the more likely there’s a cause

Young Stage 1 or Stage 2 Renin Catecholamines Angiogram Urine Steroids + Teenager Stage 1 RFP Urinalysis Renal Ultrasound + Labs & Imaging Pre-Hypertension Lipids Fasting Glucose Echocardiogram Retinal Exam
Pre-Hypertension Lipids Fasting Glucose Echocardiogram Retinal Exam LVH on an echocardiogram is the most common end-organ manifestation in pediatric hypertension Essential hypertension almost always occurs with other risk factors
Teenager Stage 1 RFP Urinalysis Renal Ultrasound Quantitate any abnormal urine protein There’s no normal creatinine in pediatrics, but there is a normal GFR. Renal vessel doppler are of questionable value.
Young Stage 1 or Stage 2 Renin Catecholamines Angiogram Urine Steroids Plasma renin is usually uninterpretable. Elevated urine catecholamines are usually transient and not subtle. Don’t bother with MRAs or nuclear scans; the gold standard is an angiogram.
