Which of the following vasoactive drugs used in treating shock results in reduced preload and afterload, reducing oxygen demand of the heart?
a) Nitroprusside (Nipride)
A disadvantage of nitroprusside is that it causes hypotension.
b) Dopamine (Intropin)
Dopamine improves contractility, increases stroke volume, and increases cardiac output.
c) Epinephrine (adrenaline)
Epinephrine improves contractility, increases stroke volume, and increases cardiac output.
d) Methoxamine (Vasoxyl)
Methoxamine increases blood pressure by vasoconstriction.
