7. The Fourth Task Force Report on Pediatric High Blood Pressure

8. 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?

10. Blood Pressure Measurement Technology is in the Dark Ages. Confirm all blood pressure readings before acting.

11. 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.

12. It’s a Pain in the A** to Detect HTN Spurious elevations are common

13. It’s a Pain in the A** to Detect HTN Not everyone has a BP reading.

14. It’s a Pain in the A** to Detect HTN Mild Hypertension takes weeks to confirm

15. It’s a Pain in the A** to Detect HTN Norms for Pediatric BP are found in a 4-D table

16. It’s a Pain, But you Got to Do it

18. Stage 2 Hypertension > 5 mm above 99%le Stage 1 Hypertension 95% to 5 mm above 99%le Pre-Hypertension 90-95% le Normal < 90% le

19. Hypertension is Common % Hypertension Asthma

20. 114 cm (75%le) 95% BP = 113/74 99% BP = 120/82 168 cm (16%le) 95% BP = 133/85 99% BP = 141/93 98 cm (64%le) 95% BP = 110/67 99% BP = 118/75 Brittiney 125/78 161 cm (72%le) 95% BP = 126/82 90% BP = 122/78 Anthony 145/87 Chris 180/115 Caleb 118/75

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

22. 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?

23. Is this an Emergency? Hypertensive Emergency Elevated Blood Pressure with symptoms of end-organ damage Hypertensive Urgency A high BP that makes you uncomfortable

24. 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

26. 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.

27. 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?

28. School Age Teenager Chronic UTIs Glomerular Disease Renovascular Disease Aortic Coarctation Essential Hypertension Essential Hypertension Glomerular Disease Renovascular Disease

29. 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

30. Rule of Thumb #1 The Younger the Patient with Hypertension, the More Likely you’ll find a Cause

31. Rule of Thumb #2 • The Higher the Blood Pressure, • the more likely there’s a cause

32. Symptoms to Ask About

33. History UAC as a newborn UTIs or febrile illnesses Medications Supplements Family History

34. Physical

35. Arm & Leg BPs B • What’s Normal? • A = B = C • A = B > C • A = B < C • A > B > C • What’s Normal? • A = B = C • A = B > C • A = B < C • A > B > C A C

36. Eye Grounds

37. Heart Findings

38. Listen for a Bruit

39. Skin CALMs of NF-1 Acanthosis Nigricans

40. Skin

41. 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

42. 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

43. 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.

44. 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.
