[The renal effects of dopamine therapy in premature infants in the first week of life].

It is known that Dopamine therapy induces loss of water and sodium on the first or second days of life. On the other hand, no studies have been published on renal function under long-term therapy. In our study we could prove an altered excretion of water and sodium as well as fractional sodium excretion in preterm infants who received dopamine for at least the first week of life. Conclusions for clinical practice are drawn.
