A descriptive study was conducted to describe acid-base alterations in working mules. Blood samples of 29 mules were analyzed and data was interpreted both by the traditional approach (Henderson-Hasselbach) and the Simplified Strong Ion Difference (Stewart). The parameters evaluated were pH, pCO2, HCO3 -, excess of base, difference of strong ions, total concentration of non-volatile buffer anions and blood lactate. Results showed that 48.3% of the individuals presented at least one acid-base disorder by the traditional approach, while 20.7% did so by the Stewart’s approximation. The alterations most commonly presented were metabolic alkalosis (20.7%), respiratory alkalosis (13.8%), hyperlactatemia alkalosis (10.3%) and strong ion acidosis (17.2%). The results between the two approaches did not show a coincidence. In conclusion, the acid-base alterations in the working mules may be due ...
