flosequinan and dopexamine

Inotropic agents are useful in increasing oxygen delivery in critically ill patients. The need for inotropic support requires careful assessment of all the available cardiovascular variables. Following the decision to stimulate contractility, the choice of inotrope should take into consideration the adrenergic receptor populations and their effects on the distribution of blood flow. All the inotropes should be administered for a predetermined effect. If this response is not realized, the inotrope should be discontinued. The indiscriminate use of these powerful but dangerous drugs should be discouraged. However, in periods of decreasing oxygen delivery and consumption, these agents improve tissue oxygenation and prevent the development of isolated or multiple organ dysfunction.
