Endocrinology- Adrenal/ Renal Flashcards
Pallor, Tachycardia and hypertension on induction of anesthesia (all else normal)
Concerning for catecholamine sure due to anesthesia–> pheochromocytoma
Precipitation of hypertension in pheochromocytoma
HTN can be intermittent end or sustained.
Precipitated by increased intra abdominal pressure, surgical procedures and meds (esp. anesthetic agents)
differentiate between alcohol withdrawal and pheochromocytoma
alcohol withdrawal takes longer to manifest and will not manifest under anesthesia
management of congenital adrenal hyperplasia
Glucocorticoids and mineralocorticoids
S&S congenital adrenal hyperplasia
Ambiguous genitalia in girls
Salt wasting syndrome (after 1wk age)
S&S acute adrenal crisis
Shocked, altered mental status, vomiting, abdominal pain, weakness, fatigue
S&S primary adrenal insufficiency
Skin hyperpigmentation, orthostatic hypotension, fatigue, weakness, muscle aches, weight loss, GI disturbances salt craving psychiatric manifestations
Hormone responsible for hyperpigmentation in PAI
Melanocyte stimulating hormone is consecrated with ACTH
Primary vs secondary adrenal insufficiency
secondary aka central is due to suppression of ACTH.
Mineralocorticoid production maintained (RAAS controlled)
No hyperpigmentation
Normal K
Electrolyte abnormalities in primary adrenal insufficiency (PAI)
Hyponatremia Hyperkalemia eosinophilia Low morning cortisol High ACTH
Tx PAI
Glucocorticoids
Mineralocorticoids
Evaluation PAI
Morning cortisol
Plasma ACTH
ACTH stimulation test (confirmation)
Medication used for ACTH stimulation test
cosyntropin is a synthetic ACTH analog
