Arterial vasodilators
What are some arterial vasodilators
Nitroprusside
Milirinone
ACE inhibit
Hyralazine
Ace inhibitors work
Pril
Venous/Arterial dilation and diuresis
Ace inhibitors SE
Dry cough
Hyperkalemia
Angiodema
Angiotensin receptor blockers work
vasodilator
Angiotensin receptor blockers thing to remember
Used when pt’s cannot tolerate ACE inhibitor
Milirone (primacor) works by
Vasodilator
Positive Inotrope
Milirinone (primacor) remember
tx for HF
Morphine works by
Venous Dilator
Dec Anxiety
Nitroglycerin works b
Venous Dilator
Arterial Dilator in high doses
Coronary artery dilator
When is nitroglycerin not recommended
SBP >90
Nitroprusside (Nipride) works by
Potent venous AND arterial dilator
Epinephrine (Adrenalin) works as a
Positive Inotrope, dromotrope, chronotrope
Vasoconstrictor
Reserved for CA and Anaphylaxis
Vasopressin (Pitressin) is used during
Refractory shock despite fluid resuscitation
Splanchnic vasoconstriction
Dec. CO
Dopamine (Intropin, Dopastat) works by
Alpha, beta-one, beta-two stimulation
Dopamine dose for increasing CO
5-10 mcg/kg/min
Dopamine dose for increasing BP
> 10 mcg/kg/min
Phenlyephrine (Neo-Synephrine) works as a
Purse alpha-agonist
4 Positive Inotropes
- Dopamine
- Dobutamine
- Epinephrine
- Norepinephrine
Negative Inotropes
CCB BB Antidyshrythmics Anesthetics Propofol Chemotherapy
