patient presented with shock with pump failure. Ideal management would be:

Ans. D: Dopamine In patients with inadequate tissue perfusion and adequate intravascular volume, initiation of inotropic and/or vasopressor drug therapy may be necessary. Dopamine increases myocardial contractility and suppos the blood pressure; however, it may increase myocardial oxygen demand. Dobutamine may be preferable if the systolic blood pressure is higher than 80 mm Hg and has the advantage of not affecting myocardial oxygen demand as much as dopamine. However, the resulting tachycardia may preclude the use of this inotropic agent in some patients.
