  2. About This Presentation • This presentation is intended for EMTs of all certification levels. We recommend that you review the slides from start to finish, however hyperlinks are provided in the table of contents for fast reference. Certain slides have additional information in the ‘notes’ section. • This presentation was created by MA EMS for Children using materials and intellectual content provided by sources and individuals cited in the “Resources” section.

  3. Table of Contents • Objectives • Anatomy & Physiology • Epidemiology • Presentation • Management • Medication Profiles • Protocol Updates • Resources

  4. OBJECTIVES • At the end of this program, EMTs will have increased awareness of: • Epidemiology • Anatomy & Physiology • Pathophysiology • Presentation • Signs & Symptoms • Treatment • Family-centered care • Effective medications

  5. Adrenal Anatomy & Physiology • The adrenals are endocrine organs that sit on top of each kidney

  6. Adrenal Anatomy & Physiology • Each adrenal gland has two parts • Adrenal Medulla (inner area) • Secretes catecholamines which mediate stress response (help prepare a person for emergencies). • Norepinephrine • Epinephrine • Dopamine

  7. Adrenal Anatomy & Physiology • Adrenal Cortex (outer area, encloses Adrenal Medulla) • Secretes steroid hormones • Glucocorticoids: exert a widespread effect on metabolism of carbohydrates and proteins • Mineralocorticoids: are essential to maintain sodium and fluid balance • sex hormones (secondary source)

  8. Adrenal Anatomy & Physiology • A person can survive without a functioning adrenal medulla • A functioning adrenal cortex (or the steady availability of replacement hormone) is essential for survival

  9. The Essential Steroids • Primary glucocorticoid: • Cortisol (a.k.a. hydrocortisone) • Primary mineralocorticoid: • Aldosterone

  10. Cortisol • A glucocorticoid • Frequently referred to as the ‘stress hormone’ • Released in response to physiological or psychological stress • Examples: exercise, illness, injury, starvation, extreme dehydration, electrolyte imbalance, emotional stress, surgery, etc.

  11. Cortisol • Critical actions on many physiologic systems, including: • Maintains cardiovascular function • Provides blood pressure regulation • Enables carbohydrate metabolism • acts on the liver to maintain normal glucose levels • Immune function actions • Reduces inflammation • Suppresses immune system

  12. Cortisol • When cortisol is not produced or released by the adrenal glands, humans are unable to respond appropriately to physiologic stressors • Rapid deterioration resulting in organ damage and shock/coma/death can occur, especially in children

  13. Aldosterone • A mineralocorticoid • Regulates body fluid by influencing sodium balance • The human body requires certain amounts of sodium and water in order to maintain normal metabolism of fats, carbohydrates and proteins

  14. Water/sodium balance is maintained by aldosterone • Without aldosterone, significant water and sodium imbalances can result in organ failure/death

  15. Why we need cortisol • Cortisol has a necessary effect on the vascular system (blood vessels, heart) and liver during episodes of physiologic stress

  16. Who has Adrenal Insufficiency? • Anyone whose adrenal glands have stopped producing steroids as a result of: • Long-term administration of steroids • Pituitary gland problems or tumor • Head trauma • Loss of circulation to adrenals/removal of tissue • Auto-immune disease • Cancer and other diseases (TB and HIV may cause)

  17. Adrenal Insufficiency • Can occur from long-term administration of steroids (over-rides body’s own steroid production) Examples: • Organ transplant patients • Long-term COPD • Long-term Asthma • Severe arthritis • Certain cancer treatments

  18. Why? • Adrenal glands tend to get ‘lazy’ when steroids are regularly administered by mouth, I.M. injection or I.V. infusion • To illustrate how quickly…Just 2-4 weeks of daily oral cortisone administration is sufficient to cause the adrenals to be slightly less responsive to stressors

  19. Primary Adrenal Insufficiency = Addison’s Disease • The adrenal glands are damaged and cannot produce sufficient steroid • 80% of the time, damage is caused by an auto-immune response that destroys the adrenal cortex • Addison’s can affect both sexes and all age groups

  20. Congenital Adrenal Hyperplasia • There is also an inherited form of adrenal insufficiency (CAH) • Diagnosed by newborn screening; prior to successful screening techniques most children died • Daily replacement oral hormones are required at a maintenance dose for LIFE • I.M. or I.V. hormones necessary for stressors (illness, surgery, fever, trauma, etc.)

  21. Vascular Reactivity • In adrenally-insufficient individuals experiencing a physiologic stressor, the vascular smooth muscle will become non-responsive to the effects of norepinephrine and epinephrine, resulting in vasodilation and capillary ‘leaking’ • The patient may be unable to maintain an adequate blood pressure • The blood vessels cannot respond to the stress and will eventually collapse

  22. Energy Metabolism • In adrenally-insufficient individuals under increased physiologic stress, the liver is unable to metabolize carbohydrates properly, which may result in profoundly low blood sugar that is difficult to reverse without administration of replacement cortisol

  23. Adrenal Insufficiency • The speed at which patient deterioration occurs is difficult to predict and is related to the underlying stressor, patient age, general health, etc. • Young children can be at high risk for rapid deterioration, even when experiencing a ‘simple’ gastrointestinal disorder

  25. Presentation of Adrenal Crisis • The patient may present with any illness or injury as the precipitating event • A patient history of adrenal insufficiency warrants a careful assessment under specific protocols • Children may deteriorate into adrenal crisis from a simple fever, a gastrointestinal illness, a fall from a bicycle or some other injury • A mild illness or injury can easily precipitate an adrenal crisis in any age group

  26. Critical Clinical Presentation • The early indicators of an adrenal-crisis onset can be vague and non-specific. Some or all signs/symptoms may be present. • Infants: • Poor appetite • Vomiting/diarrhea • Lethargy/unresponsive • Unexplained hypoglycemia • Seizure/cardiovascular collapse/death

  27. Critical Clinical Presentation • Older Children/Adults • Vomiting • Hypotensive, often unresponsive to fluids/pressors • Pallor, gray, diaphoretic • Hypoglycemia, often refractory to D50 • May have neurologic deficits • Headache/confusion/seizure • Lethargy/unresponsive • Cardiovascular collapse • Death

  28. Critical Clinical Presentation • Clearly, the signs/symptoms of adrenal crisis are similar to other serious shock-type presentations. • For these patients, standard shock management requires supplementation with corticosteroid medication. • It is important to ANTICIPATE the evolution of an adrenal crisis and medicate appropriately under the specific protocols. Do not wait until a full adrenal crisis has developed. Organ damage or death may result from delays.

  29. Patient Management • Follow standard ABC and shock management treatment. • BLS: Transport without delay • ALS: allow patient or caregivers to administer patient’s own steroid IM as soon as possible after initial life-threat and shock management have been initiated • Transport without delay to appropriate hospital with early notification

  30. Patient Management It is important to note that you are caring for a patient with multiple issues: 1. The precipitating event (a trauma/illness that may be a critical issue on its own) and 2. The evolution towards adrenal crisis, which will result in organ failure/death if not reversed

  31. Patient Management • Administration of steroid medication should come as soon after appropriate A-B-C assessment and interventions as possible • Your emergency management priorities remain the same.
