The dose of Dopamine used for renal vasodilatation is?
Dopamine is used in the treatment of shock - cardiogenic, hypovolemic, and septic shock. It is especially useful when there is renal dysfunction and low cardiac output because dopamine increases renal blood flow and thereby GFR. Dopamine stimulates the hea - increases FOC, CO, BP. It is also sho acting. Its dose is 2-5 mcg /kg/ min for stimulating the hea (beta-1) least does- renal VD. 1-2 mcg /kg/ min- Dopamine receptor stimulation more than 10mcg /kg/ min not to be used as alpha receptors may get stimulated causing vasoconstriction From medical pharmacology Padmaja 4th edition page 97
