There are three adrenal issues that we are focusing on. List them.
Cushing Syndrome
Addison's disease
Pheochromocytoma
Define if the cortisol levels are UP (hyper) or DOWN (hypo) in each of the following problems:

Cushing Syndrome
Addison's disease
Cushing Syndrome - hyper secretion
Addison's disease - hypo secretion
What is cortisol's role in pheochromocytoma?
Cortisol is not a focus in this disease. Catecholamines are the issue. They are produced by benign tumors. The catecholamines cause vasoconstriction resulting in HTN 200-300/150-175 that comes and goes
How do you diagnose pheochromocytoma?
urine and blood have increased catecholamines
What is treatment for pheochromocytoma?
surgical removal of tumors
Name some catecholamines that are over produced in pheochromocytoma.
Epinephrine and norepinephrine

(so now you understand the vasoconstriction)
Other manifestations (other than the severe high BP) of pheochromocytoma include....
pounding headache
tachycardia with palpations
profuse swweating
unexplained abd and chest pain
ANXIETY

There is a triad of symptoms for pheochromocytoma. They include:
1. pounding headache
2. tachycardia
3. profuse sweating
What test would you expect to have to do for a patient that is admitted to r/o pheochromocytoma?
24 hour urine collection
Any surgery on adrenals, what are the post op priority assessments/interventions to be performed?
monitor vitals, especially BP

fluid balance (edema, congestion, i/o)

electrolyte imbalances
Why is there a fluid balance problem post op of adrenalectomy?
manipulation of the adrenals during surgery causes a great amount of cortisol to be released into the system. Because of this, BP, fluid balance and electrolyte levels seem to be unstable.
We tend to think that cushing's syndrome is a problem with only cortisol. In fact, there is another player in this game.....name him.
ACTH - adrenocorticotropic hormone

If this is the problem, then it is called CUSHING's DISEASE. Cushing's disease is a pituitary tumor causing increased secretion of ACTH
What are the manifestations of Cushing's Syndrome?
buffalo hump

round moon face

apple bottom jeans...just kidding (apple body with stick legs)

osteoporosis **remember this

purple striae

hirsutism

HTN (think overweight people usually have HTN)

slow wound healing

ecchymosis

thin skin and subcu tissue
What type of wound dressing would you use on a Cushing Syndrome patient, and why?
abdominal binder or montgomery straps (corset)

b/c of their poor skin condition, their skin could tear with tape
What is a diagnostic test that is used to dx Cushing syndrome? (name multiple)
plasma cortisol - loss of circadian rhythm

plasma ACTH - increased in primary, decreased in secondary

24 hour urine ***

serum Na & glucose elevated

serum K decreased

CT and MRI for tumor

ACTH Suppresion Test ***
Why would you use a 24 hour urine collection to diagnose Cushing syndrome?
the elevated level of free cortisol in the urine can indicate cushing syndrome
Describe the ACTH suppresion test.
Dexamethasone (strong steroid) given to patient to suppress ACTH production. Then they measure the cortisol levels

If cortisol level is extremely high, then they think it is a "cortex" problem

If ACTH is not suppressed, adrenal tumor is suspected.

So, this is to determine the cause of the cushing syndrome.
What is the name of the drug that suppresses cortisol function?
Mitotane

(get me SOME!!!! decreased cortisol=tan and skinny remember!!!! haha)
What is the name of the drug that suppresses ACTH secretion?
Somatostatin

Cushing/mitotane/Somatostatin
What is the "problem" in Cushings disease?

(repeated info)
Too much cortisol

Maybe too much ACTH

Too much steroid intake
In addition to mitotane (decreases cortisol) and Somatostatin (suppresses ACTH), what is another drug used to treat Cushing syndrome?
aminogluthemide or ketoconzale
Patient teaching to include for a patient with Cushing syndrome that has been given an RX for ketoconazole or aminoglutethimide....
GI upset take WITH FOOD
GI bleed, depression, vertigo, skin rashes and diplopia...take WITH FOOD
Your patient is going to have a bilateral adrenalectomy tomorrow. What type of pre op instructions do you give her in regard to post op meds she will receive?
she will be on life long hormone replacements
PACU calls and says that you are getting a patient that just had unilateral adrenalectomy. What are your top assessment priorities when she gets up to the room?
Monitor vitals, especially BP. (you are looking for hypertension from mass amounts of hormone released)

Hemorrhage (which is increased with HTN and b/c the adrenals are very vascular)

Hemorrhage will cause drop in BP, but increase in HR. Report any changes in BP, HR and R.

Assess for fluid balance (i/o). looking for edema, congestion, FVE,

Look for electrolyte imbalances (especially Na, K)

Look for hyperglycemia...so monitor BG
Why are you anticipating a problem with glucose for a patient that just had an adrenalectomy?
b/c increased cortisol causes increased glucose in blood. Cortisol is the enemy of insulin.
Why would there be electrolyte imbalances in your post op adrenalectomy patient?
b/c of fluid shift, IV fluids
PACU calls again and says they have ANOTHER adrenalectomy coming to your unit. What type of equipment do you expect to be inplace on this patient?
ng tube (so get suction set up)

urinary catheter

IV therapy (running both fluids and corticosteroids)

central venous pressure monitoring (book says this...)

SCDs to prevent emboli

abdominal dressing (maybe with a binder b/c of skin condition)
Preparing for your post op adrenalectomy patient, what type of meal do you order from dietary?
High protein
High potassium
low in calories
low in CHO
low in salt

chicken, bananas, no chips, no bread roll....
When you are monitoring vitals for post op adrenalectomy patient, why is temperature important to watch?
b/c of increased risk of infection due to increased level of coritsol/corticosteroid IV
Connect the dots between:

hypercorticolism and increased risk of infection/delayed wound healing
Think diabetic....high glucose in blood. Cortisol is enemy of insulin. High glucose in blood delays wound healing. Bad m/o love glucose...immune system suppressed, so increased risk of infection
List other "duh" things to do post op for adrenalectomy.
TCDB/IS q 2 hr

strict med/surg asepsis

passive ROM if bedridden

activity balanced with rest

safe environment

emotional support
Yea! These post op adrenalectomy patients are being discharged. You are going to send them home with a prescription for ____________ and make sure you tell them....
steroids

You will take these FOREVER, take in the AM so you can sleep, take with FOOD to decrease GI upset.

If you get ill, here is another prescription for IM cortisol. You want to use this route when you are ill and can't keep food down.

Instruct family members how to inject IM (after you look it up in pharm packet, uhg!)

Instruct them to increase amount of steroid if stressed or ill (hopefully prescription will tell you how much...)
Along with med education you have just provided to your adrenalectomy patient, you also must remember to instruct them to always carry _____________________ with them.
a medical alert/id bracelet

(fashion advice)
The soon to be discharged adrenalectomy patient asks, "How do I know that I am taking the right amount of this life long steroid replacement?". You respond by explaining the symptoms of steroid UNDERUSE and OVERUSE.
Underuse - fatigue, weakness, dizziness

Overdose - severe edema, wt gain
If a person on steroid therapy abruptly stops, what can happen?
fatal adrenal crisis
There are four main effects of corticosteroid therapy. List them.

What is the biggest complication that can happen to a person with Addison's disease?
Addisonian crisis
What test do they use to diagnose Addison's disease?
ACTH stimulation test (cortisol is low)

Plasma cortisol (decreased) **

Plasma ACTH

24 hour urine for free cortisol

Glucose, Na decreased, K and BUN up ***
Why is the BUN elevated in Addison's disease?
renal insufficiency
What type of diagnostic lab would include the electrolyte panel?
Chem 7, 9, 15

BMP
Why is glucose down in Addison's disease?

(think relation of cortisol to glucose)
in Addison's disease, the low level of cortisol means there is less "messing with" insulin. When insulin can do its job, it will drive glucose into the cells, thus decreasing the BG level.

Cortisol and Insulin are enemies

Addison's disease has low cortisol, so insulin is working. Result is LOW Blood Sugar
What are the treatments of Addison's disease?
hydrocortisone therapy - replaces cortisol

fludrocortisone acetate - replaces mineralocorticoids
Although replacing the cortisol can treat Addison's disease, what should the focus of treatment be on?
the underlying cause
