Hypertension in Spinal Cord Patients

Hypertension is…

Systolic BP > 140 mmHg

OR

Diastolic BP > 90 mmHg

Regulation of Blood Pressure

Baroreceptor Reflex

One Significant Difference in SCI…

Parasympathetic

Sympathetic

Autonomic Dysreflexia

Etiology

What to watch for…• Sweating above the level of injury

• Hypertension

• Nausea

• Cold, clammy skin below the level of injury

• Goose bumps

• Blotching of the skin

MNT for Hypertension

• Potassium• Magnesium• Fruits/veggies• Lean meats• Healthy fats• Whole grains

• Highly processed meats and cheeses

• High sugar foods• Sedentary lifestyle

Special Considerations

Smoking cessation

Adequate fluid intake

Lose excess weight

B.B. – 75 y/o WM• Diagnoses: atherosclerosis of extremities with gangrene, pressure

ulcers, GERD, DB, Autonomic Dysreflexia, HTN, hyperlipidemia

• Admitted June 2013 for worsening pressure ulcers

• Allergies: Amikacin, hydrochlorothiazide

• Current medications:• Laxative/Stool softener : Docusate• Antihypertensive: Metoprolol• DB regimen: SSI, 6 units @ bedtime, 16 units every morning• Vitamin D2: ergocalciferol

• Bowel training 3x/week

B.B.• Currently on a 2200 CHO diabetic diet

• Supplements include 1 Prostate with each meal (discontinued Boost Glucose Control 10/24)

• Main concern: maintain blood sugars <180 and heal pressure ulcers
