Extra CARDIAC drugs

Question 1

what are the 7 cardiac drugs paramedics can give

Answer 1

adernaline 1:10,000
amiodarone
asprin
atropine
furosemide
GTN
Morphine

Question 2

what are the pharmacodynamics for catecholamine

Answer 2

this is a non selective sympathomimetic.
agonises alpha- and beta- adrenoreceptors in the cardiac, pulmonary and blood vessel tissue leading to tachycardia, bronchodilation and vasoconstriction

Question 3

what is the pharmacodynamics for alpha adrenoreceptors

Answer 3

Alpha-adrenoreceptor stimulus increases peripheral resistance, resulting in increased myocardial
and cerebral blood flow during CPR.

Question 4

what is the pharmacodynamics for Beta-1 adrenoreceptor agonist

Answer 4

this is a positive inotrope (increased contractility), chronotrope
(increased frequency of SA node depolarisation) and dromotrope (increased conduction through AV
node)

Question 5

what is the pharmacodynamics for Beta-2 adrenoreceptor

Answer 5

this stimulus causes smooth muscle relaxation, notably in the lungs, causing
subsequent bronchodilation, consequently improving ventilation and aiding oxygenation. Also, a
histamine antagonist.
