ABSTRACT
Plasma norepinephrine and epinephrine levels were monitored to determine possible alterations of the sympathetic nervous system caused by hypertonic fluid adeministration. Iv infusion (3.5 ml/Kg, 1 min) of 7.5% NaCl/6% Hespan transiently increased both plasma norepinephrine and epinehrine levels to 197 ñ 28% and 220 ñ 30% of control, respectively, at 1 min. These increases were no longer significant 5 or 15 min following infusion. A brief hypotension was also observed immediately following hypertonic fluid administration. This, prolonged sympathetic activation does not occur following hypertonic fluid infusion in normovolemic conscious rats
