all secretions from adrenal gland
glucocorticoids or cortisones
lrg amt in morning,less at night
negative feedback
hypohalmus -CRH-stimulates ant.pit. ACTH-which stim.adrenals to release glucocorticoids
Effects of Glucocorticoids
desired & adverse
decreases secretion-atrophy
withdrawal results in adrenal crisis, must be gradual w/drawal
inhibits inflammatory resp.-increases susceptibility to infection
increased NA & H2O retention(edema) -results in HTN, and decreases serum K+
cushing syptoms
GI disturbance-irritation or PUD
Hyperglycemia-increase glucose-breaks down protein into amino acids,
catabolic effect-muscle wasting, slowed wound healing & thin Skin
CNS effects-depression or euphoria
Osteoporosis-dec.abs.of Ca and inc. renal excre.of Ca
many synthetic corticosteroid drugs used in treatment of inflammation & pain ex: Arthritis
Nursing Implications
be careful:
pts w/PUD,HTN,infection,diabetes
admin of ASA & NSAIDS cautiously
black stools, NG drain for blood
monitor wgt, bl pressure, labs
Inflammation: Glucocorticoids
adrenal crisis
inhibits inflammation (good)
which can increase susceptibility to infection(comes quickly) (bad)-(keep sterile environment in hospital)
Cushing symptons
GI problems
catabolic effect
CNS effects
GI disturbance
Catabolic effect
CNS effect
-water & Na retention, K+ loss, HTN,
-PUD- irritation
-increases glucose,decreases insulin production
-breaks down protein so decreases protein synthesis, results in muscle wasting, slowed healing, bruising, thin skin
-depression or euphoria
-decreases intestional absorption of Ca and increases renal excretion of Ca-long term use
adrenal crisis
body quits making glucocorticoid because you are getting it synthetically so must withdraw slowly
Nursing implications for Glucocorticoids
be careful with:
pts w/PUD,HTN,infection,diabetes
-give cautionusly w/ASA & NSAIDS
-checks stools & NG drainage(coffee grain look)
-monitor wgt, bl.pressure & lab values (edema effect & increase glucose must increase insulin)
-feed high protein/low carbs (sugar), high K+ foods/low sodium (cheese products are good)
-stay away from those w/infections & report infections to MD (run low fevers & look for pink around wounds-stops inflammation)
-no vaccinations
-carry medical ID
-watch for depression
-prepare them for Cushingoid appearance
-if on for longer than 1 wk, then should not stop drug abruptly

look up if going to give
in organ transplants
used concurrently for synergistic effect
inhibit or modify the immune system
highly protein bound
many drug interactions
no immunizations until d/c
s.e.: infection-fever,sore throat, wound drainage, cough, dysuria
Nephrotoxicity-creatinine levels & Bun levels,decreased urinary output
Bun levels
blood, urine, nitrogen
use for any anti-rejection drugs-must drink lots of fluid and excrete lots of fluid-renal function
hyperuricemia & severe joint pain, renal calculi

inhibits exc. of many drugs (ex: penicillian-this s.e.can be used as benefit)
n.i: do not give w/ASA-decreases the effect
take w/meals
increase fluid intake**-stops renal calculi
eat vegs to alkalinize the urine

Gold salts
last choice drug-
takes 4-6 mths, prevents joint degeneration-stops breakdown, but does not reverse damage,
given w/NSAIDS

Cell cycle
diff body cells go through cell cycles at diff. speeds
-most rapid dividing normal cells are bone marrow, lining of the GI tract, and hair follicle
-cancer cells cycle faster than normal cells-have less Go resting phase time
Cell cycle specific
agents that are lethal only if the cell is dividing or preparing to divide
Cell cycle non-specific
agents that damage the DNA molecule and do not depend on the cell being in a particular cycle
-this can damage cells even in the Go phase
