Graded A+
Alpha 1 vasoconstriction
Alpha 2 Vasodilation and decreased BP.
Beta 1 Effects the heart
Beta 2 Effects the lungs
Norephinephrine (Levophed) Beta 1 and alpha stimulant. For hypotension, maintain end-
organ perfusion. Increases contractility, increases heart rate , increases SVR, increases BP and
coronary blood flow. Side effects: tachycardia, dysthymias, hypertension, peripheral limb
ischemia. Dosage: 0.02-0.05 mcg. Considerations: very rapid onset , half life is 2 mins , correct
hypovolemia before initiating
Epinephrine Beta 1 Beta 2 Alpha stimulant. Indication: hypotension, inotropic support,
anaphylaxis. Effects: increases contractility, increases HR, SVR, relaxes smooth muscle of
bronchial tree, produces cardiac stimulation. Side effects: tachycardia, hypertension,
hyperglycemia, myocardial ischemia, dysthymias. Dosage: 0.05-1 mcg. Considerations : monitor
blood glucose, 2 min half life, never ivp unless dead , IM inject for anaphylactic
Vasopressin antidiuretic hormone. Indication : hypotension, used as an adjunct when
vasopressors and fluid resuscitation are ineffective in maintaining goal BP/MAP. Effects: ADH
causes vasoconstriction, water retention and urine concentration in order to increase SVR. Side
effects: myocardial ischemia, abdominal cramps , nausea vomiting, confusion, hyponatremia.
Dosage: 0.01-0.04 units. Considerations: fixed dose, 10-20 mins half life
Phenylalanine ( neo synephrine ) Alpha stimulant. Indication: hypotension. Effects:
produces systemic arterial vasoconstriction ( increases SVR ). Side effects : 0.25-5mcg.
Considerations: Dr must be present or responding to beside for ivp , admin thru central line ,5
min half life
