RESUMO

Dehydration is one of the most common disorders in the veterinary medicine. Fluid therapy is used to correction of fluid, electrolyte and acid-base disorders. 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. This animals were treated with three different solutions: Lactated Ringers solution (RL), Ringers 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, albumin and osmolality that decrease after fluid therapy. It was not observed an increase of urinary density and pH become more acid during dehydration. The serum concentration of Na+, Cl-, K+, iCa++ and lactate had discreet variations between the studied times. It was observed increase of serum glucose in the GF group during rehydration phase. In the acid-base evaluation was observed an increase in pH, tCO2 and bicarbonate concentration in RL group and a slight decrease in base excess in RS group.
