Q: Which of the following two inotrope, is of choice in cardiogenic shock due to Right Ventricle dysfunction? (select one)

1) Dopamine 
2) Dobutamine


Answer:  Dopamine

Dopamine is usually more effective than Dobutamine in cardiogenic shock due to right ventricular dysfunction. It can be started 5 mcg/kg/minute, and titrated up with close watch for tachycardia. Though Dobutamine is an excellent inotrope, it decreases systemic vascular resistance, which may become detrimental in shock situation.
