Contra indicated in patients hypersensitive to drug and in those with idiopathic hypertrophic subaortic stenosisUse cautiously in patients with history of hypertension because drug may increase pressor responseUse cautiously in patients with history of sulfite sensitivity

.

Increased heart rate, hypertension,Angina, phlebitis, nonspecific chest pain, palpitations, hypotension, nausea, vomiting, shortness of breath, hypersensitivity reactions

Before starting dobutamine therapy: (1) give a plasma volume expander to correct hypovolemia (2) give cardiac glycoside

Inotropic, vasopressor

Stimulates dopaminergic and alpha and beta receptors of the sympathetic nervous system. Action is dose-related; large doses can cause mainly alpha stimulation.

To treat shock and correct hemodnamic imbalances, improve perfusion of vital organs, to increase cardiac output, and to correct hypotension.

Contraindicated in patient with uncorrected tachyarrhythmias, pheocromocytoma, or ventricular fibrillation.- Use cautiously in patients with occlusive vascular disease, cold injuries, diabetic endarteritis, and arterial embolism; in pregnant woman; with a history of sulfite sensitivity; and in those taking MAO inhibitor.

Other: anaphylaxis.

Blood is not a substitute for blood or fluid volume deficit. If deficit occurs, replace fluid deficit first before giving meds.

During infusion, frequently monitor ECG, BP, cardiac output, CVP, pulmonary artery wedge pressure, pulse rate, urine output, and color and temperature of the limbs.

If diastolic pressure rises disproportionately, decrease perfusion rate and watch out carefully for further signs of vasoconstriction unless such action is desired.

Acidosis decrease effectiveness of dopamine.
