LAST MINUTE ADRENERGICS

Question 1

anaphylaxis
first line
cardiac arrest and asystole
bradycardia
local anesthetics

direct acting, non selective
a1, a2, b1, b2

Answer 1

epinephrine

Question 2

antidote for vasopressor extraction?

Answer 2

phentolamine (alpha-antagonist)

Question 3

first line and used for shock

direct acting, non selective

a1, b1, b2

Answer 3

norepinephrine

Question 4

treatment of bronchospasms, shock, cardiac arrest, AV block

non selective B agonist, b1=b2 > alpha

Answer 4

isoproterenol

Question 5

precursor to NE
direct acting, non selective a1,a2, b1,d1,d2

shock
advanced heart failure

low dose: increase urine output and Na excretion, increase GFR

medium dose:
cardiac stimulation

high dose:
increase blood pressure, more vasoconstriction

Answer 5

dopamine

Question 6

selective B1 agonist mostly, more so than A1, B2

refractory heart failure
cardiogenic shock

Answer 6

dobutamine

Question 7

selective a1 agonist only used for hypotension/shock, anesthesia induced hypotension, mydriasis, nasal decongestant

Answer 7

phenylephrine
