EVALUATION OF COMMERCIAL CRYSTALLOIDS ADMINISTERED EXPERIMENTALLY BY INTRAVENOUS ACCESS IN DEHYDRATED DOGS BY RESTRICTION AND POLYURIA

Abstract

This study was made to compare the effect of three electrolytic solutions administered by intravenous access. Six male adult dogs, weighting 5 and 15 kg were submitted to a dehydration protocol by restriction and polyuria induced by furosemide. This animals were treated with three different solutions: Lactated Ringer’s solution (RL), Ringer´s solution (RS) and Normal saline (0,9%) plus dextrose (5%) (GF). The variables were evaluated before (T0) and 24h after dehydration, during hydration between 6h (T2) and 12h (T3) and after 12h hydration (T4). The data were expressed in range ± standard deviation and submitted to variance analysis and non-parametric tests (p<0,05%). The dehydration protocol used in this study was enough to cause slight to moderate dehydration that was observed by the increase of packed cell volume, serum protein, urea, creatinine and osmolality that decrease after fluid therapy. The serum concentration of  Na⁺, Cl ^– and K⁺ had discreet variations between the studied times. It was observed increase of serum glucose in the GF group during rehydration phase.
