【 摘 要 】

The effects of lactated Ringer's solution (LRS) on fluid, electrolyte and acid-base balances were investigated in healthy horses, ewes and calves. LRS was intravenously infused in six adult horses, six adult ewes and five calves in a volume corresponding to 10% of body weight, continously during four (ewes and calves) or six (horses) hours. Venous blood and urine samples were taken before the beginning, in the middle, at the end of the infusion and two (ewes and calves) or three (horses) hours after. Blood and urine pH, blood pCO2, HCO3- and BE, serum Na+, K+ and Cl-, and plasma TP and L lactate were measured. Na+, K+, Cl- and L lactate fractional clearance and plasma SID, AG, and Atot were calculated. In all species LRS caused hemodilution but didn't change electrolyte and acid-base balances. It was not able to increase alkali reserve. On the other hand, LRS must be considered safe for maintenance therapy with large volume infusions because it doesn't induce electrolyte imbalances.
