OBJECTIVES

At the end of this program, EMTs will have increased awareness of:EpidemiologyAnatomy & Physiology

• PathophysiologyPresentation

• Signs & SymptomsTreatment

• Family-centered care• Effective medications

Adrenal Anatomy & Physiology

The adrenals are endocrine organs that sit on top of each kidney

Each adrenal gland has two partsAdrenal Medulla (inner area)

• Secretes catecholamines which mediate stress response (help prepare a person for emergencies).

• Norepinephrine• Epinephrine• Dopamine

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)

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

Adrenal Anatomy & Physiology

The Essential Steroids

Primary glucocorticoid:Cortisol (a.k.a. hydrocortisone)

Primary mineralocorticoid:Aldosterone

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.

Cortisol

Critical actions on many physiologic systems, including:Maintains cardiovascular functionProvides blood pressure regulationEnables carbohydrate metabolism

• acts on the liver to maintain normal glucose levels

Immune function actions• Reduces inflammation• Suppresses immune system

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

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

Water/sodium balance is maintained by aldosterone

Without aldosterone, significant water and sodium imbalances can result in organ failure/death

Why we need cortisol

Cortisol has a necessary effect on the vascular system (blood vessels, heart) and liver during episodes of physiologic stress

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)

Adrenal Insufficiency

Can occur from long-term administration of steroids (over-rides body’s own steroid production) Examples:

Organ transplant patientsLong-term COPDLong-term AsthmaSevere arthritisCertain cancer treatments

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

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

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.)

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

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

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

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

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 appetiteVomiting/diarrheaLethargy/unresponsive

• Unexplained hypoglycemiaSeizure/cardiovascular collapse/death

Critical Clinical Presentation

Older Children/AdultsVomitingHypotensive, often unresponsive to fluids/pressors

• Pallor, gray, diaphoreticHypoglycemia, often refractory to D50May have neurologic deficits

• Headache/confusion/seizure• Lethargy/unresponsive

Cardiovascular collapseDeath

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.

Critical Clinical Presentation

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 initiatedTransport without delay to appropriate

hospital with early notification

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)

and2. The evolution towards adrenal crisis, which will

result in organ failure/death if not reversed

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.
