title: Endotoxemia and the effects of dopamine on renal functions of neonatal piglets.
abstract: In this study, we observed the effects of moderate and high doses of dopamine on the renal functions of neonatal piglets during endotoxic shock. We found that fluid therapy alone was better at maintaining cardiac index and preventing elevation of systemic vascular resistance, than dopamine at 10 and at 20 microg/kg/min. Furthermore, urine output and glomerular filtration rate were reduced by dopamine. Following endotoxin administration dopamine decreased SVR and maintained a CI better than fluid alone. However, in spite of a better CI, greater deterioration in renal functions occurred in the dopamine groups as compared to the fluid group.
