Blood gas analysis and anion gap in horses treated with enteral electrolyte solutions containing different energy sources

The present study compared the effects of electrolyte solutions containing different sources of energy that were administrated through enteral route by naso-esophageal probe of small-caliber with continuous flow on the acid base balance in horses. Six adult females were used in two simultaneous 6x3 latin squares mixed model. The animals were divided into three groups and received the following treatments: SEDext - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of dextrose diluted in 1.000mL of water. The osmolality measured was of 228mOsmol L-1; SEMalt - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of maltodextrin diluted in 1.000mL of water. The osmolality measured was of 181mOsmol L-1 and SEProp - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of calcium propionate diluted in 1.000mL of water. The osmolality measured was of 282mOsm L-1. The electrolyte solutions were administered in a dose of 15mL kg-1 h-1 for 12 hours. The treatments with enteral electrolyte solutions containing dextrose, maltodextrin and calcium propionate did not change blood gas analysis values in these animals.
