Dobutamine in shock

Dobutamine

Dobutamine is a synthetically derived catecholamine that acts on β1-adrenergic receptors. It is used to increase cardiac

contractility in situations where little dilation of the peripheral vasculature is desired. The combination of increased contractility and decreased afterload is helpful in maintaining cardiac output in patients with a weakened heart. However, due to the decrease in systemic perfusion, it should be used cautiously in hypovolaemic states.
