Question | Answer |
Pheochromocytoma | functional chromaffin cells produce excess catecholamines-stimulate autonomic nervous system-catecholamines, adrenal and, norepinephrine rain. |
Pheochromocytoma | catecholamine producing tumor cells, usually found in the adrenal Mejia law daddy is the adrenals are little hats on top of the kidneys remember. |
Adrenal glands are divided into | and outer cortex and an inner would do the; each area see creeds specific hormones. |
What does the adrenal mood do less secrete | catecholamines-epinephrine and norepinephrine for the fight or flight system. |
Where can catecholamine producing tumors be found in the body | usually in the adrenal medulla, but may be found throughout the body- including the lung, bladder, abdomen, and brain and they will secrete catecholamines from these sites |
Pheochromocytoma | is this tumor benign? Usually, but it can be a malignant tumor. |
Pheochromocytoma - typical triad of symptoms | patients with functioning tumors of the adrenal Medulla-hypertension with a triad of symptoms-headache, diaphoresis, and TACHYCARDIA (palpitations) |
Pheochromocytoma | HYPERGLYCEMIA -due primarily to catecholamine stimulation of lipolysis (breakdown of stored fat) leading to high levels of free fatty acids and the subsequent inhibition of glucose uptake by muscle cells. |
Pheochromocytoma | stimulation of beta-adrenergic receptors leads to glycogenolysis and gluconeogenesis and thus elevation of blood glucose levels). |
Pheochromocytoma HYPERTENSION | excess catecholamines cause hypertension, which may be intermittent or persistence. |
Pheochromocytoma | paroxysmal or sustain hypertension (SEVERE) with severe headache, tachycardia, flushing and profuse diaphoresis |
Pheochromocytoma | Five H's - hypertension, headache, hyperhidrosis (excessive sweating); hypermetabolism and hyperglycemia |
Pheochromocytoma HYPERTENSIVE EPISODE | extremely high blood pressure-may reach 300/180 - could cause shock, stroke, renal failure, dysrhythmias, dissecting aortic aneurysm and may result in death. |
Pheochromocytoma | S/S - other signs and symptoms palpitations, pain in the chest or abdomen with nausea and vomiting, heat intolerance, weight loss, tremors |
Pheochromocytoma - Diagnostic tests | 24-hour urine collection for INCREASED vanillylmandelic acid (VMA) - a byproduct of catecholamine metabolism |
Pheochromocytoma - Diagnostic tests | INCREASED metanephrine, INCREASED catecholimines (normal range 14 mcg/100mL0 |
Pheochromocytoma - Diagnostic tests | tumor can be located by CT and MRI. |
Pheochromocytoma - Treatment | medications to prevent or treat the severe hypertension |
Pheochromocytoma - Treatment | block alpha adrenergic receptors -phentalamine (Regitine, Rogitine) |
Pheochromocytoma - Treatment | Propranolol (Inderal) - beta blocker |
Pheochromocytoma - Test | phentalamine (Regitine, Rogitine) - used as an aid in the diagnosis and treatment due to phenol chromos site, prior to enduring surgery |
Pheochromocytoma - another test | Clonidine (Catapres) - usually, this drug suppresses catecholamines-therefore, if drug is administered and catecholamines are not suppressed, they are coming through tumor. |
Pheochromocytoma | symptomatic treatment is initiated if surgical removal is not possible |
Pheochromocytoma | complications-hypertensive crisis-can be severe-hypertensive retinopathy and nephropathy; cardiac enlargement; dysrhythmias, CHF, MRI, stroke |
Pheochromocytoma | complications-hypertensive crisis - dissecting aortic aneurysms due to extremely high blood pressure |
Pheochromocytoma - monitor | IMPORTANT - get accurate BP; use same arm, need orthostatic BP, be sure to use a palpable estimate an appropriate size of cough |
orthostatic BP | patient lies flat for 10 min.-take initial BP and heart rate; we've BP cuffs. I; patient sits on edge of bed-take another BP; then, have patient standing at the side of the bed |
Pheochromocytoma - pre-op | maintain medically-there is great risk for hypertensive crisis |
Pheochromocytoma - prost-op | post op, there is risk for hypotension - also limit activity |
Pheochromocytoma - | IMPORTANT - monitor for hyperglycemia-zero Lupo close levels should be watched and hydration (remember 5 H's - ) |
Pheochromocytoma - **IMPORTANT** | DO NOT PALPATE ABDOMEN - identify and avoid stimuli that can precipitate a hypertensive crisis pressure on the abdomen could result in the release of catecholamines |
Pheochromocytoma - **IMPORTANT** | DO NOT PALPATE ABDOMEN - Adrenal glands are located on top of the kidneys palpating abdomen could set off release of catecholamines |
Pheochromocytoma - EMERGENCY MEDS | prepare to administer a beta atria allergic blocking agent to control hypertension - Propranolol (Inderal) |
Pheochromocytoma - | dyads-high calories, vitamins, minerals |
