VALDES RESTREPO, Camila et al. Determination of the physiological plasmatic values of sodium, potassium and ion calcium and its pre and post exercise variations in "Paso Fino" horses in the Bogotá savannah. Rev. Med. Vet. [online]. 2010, n.20, pp.71-80. ISSN 0122-9354.

This research intends to be a contribution to the Colombian sports equine medicine by providing data on electrolytes standards, a field where there is a substantial lack of literature. This research analyze and determines the normal values of sodium (Na⁺), potassium (K⁺) and ion calcium (iCa2⁺) electrolytes for Colombian Paso Fino horses. The establishment of the reference intervals was done at rest and after exercise. To achieve this, blood samples were taken from farms located in the Bogotá savannah. The 115 mares and stallions used for this study were actively competing with ages ranging from 43 to 78 months old. The samples were taken at three intervals: T₀ (Rest), T₁ (inmediately after 45 minutes of exercise), and T₂ (1 hour post exercise). The samples were processed using a portable blood analyzer i-STAT^® and the data was interpreted using descriptive and comparative statistic according to Tukey tests. The normal values for the breed were established and an electrolytic behavior curve was created, using values inside intervals at 95% confidence levels. The values obtained in mEq/L were: for T₀: Na⁺ (136,71+/-0,23), K⁺ (4,05+/-0,03), Ca²⁺ (1,58+/-0,006); for T₁: Na⁺ (136,44+/-0,24), K⁺ (3,92+/-0,24), Ca²⁺ (1,42+/-0,008); and for T_2: Na⁺ (137,32+/-0,23), K⁺ (3,68+/-0,03), Ca²⁺(1,51+/-0,009). Na⁺ values increased after exercise. On the contrary K⁺ and Ca²⁺ values didn't increase in T₁. Calcium increased on T₂ and K⁺ decreased. The findings of this research will serve as a framework for future analysis. Moreover, further studies and developments in this field is recommended and will prove to be very useful for equine practitioners.
