Abstract: | A rehydration with 7 ml/kg/h for six hours prior to indomethacin administration prevented the adverse effects of this drug on renal function in prematures with persistent ductus arteriosus. During the 36 hour observation period after indomethacin administration, no significant changes in serum creatinine, sodium, and potassium concentrations, or urinary flow, creatinine clearance, or filtered sodium could be detected. The only significant finding was a reduction in fractional sodium excretion. One can assume that this beneficial effect of the fluid load is due to a suppression of some parts of the vasoconstrictor mechanisms, which are responsible for the deterioration of renal function in newborns during indomethacin therapy. Using this modified fluid regimen, no cardiovascular side effects were noticed, a closure of the duct was achieved in 7 of 10 treatment courses. |
