The alkalinizing power of Lactated Ringer’s Solution (LRS) was searched in this work. Six crossbred healthy ewes, nonpregnant and nonlactating, weighting approximately 40 kg, received 4 L of LRS by 4 hours continuous intravenous infusion at a rate of 25 mL/kg/h. The venous blood samples were obtained before the infusion (0 hours), during the infusion (2 hours), at the end of the infusion (4 hours), and 2 hours after the end of the infusion (6 hours). Values of pH, pCO2, HCO3-, TCO2, BE, Na+, K+, Cl- and lactate L were determined. The LRS induced mild increase in the alkali reserve confirming its low magnitude alkalinizing power, as a result of the small sodium lactate concentration present in the solution.
KEY WORDS: Sheep, acid-base balance, sodium lactate, intravenous solution.
