Avaliação de distúrbios hidroeletrolítico e ácido/básico em equinos com síndrome cólica.

Abstract

Evaluation of hydroelectrolytic and acid/base disorders in horses with colic syndrome. Hydroelectrolytic and acid-base disorders are common alterations found in horses affected by colic syndrome, so that the correction of these disorders contributes to the reestablishment of the animal body homeostasis. The purpose of this research was to detect in which situations of hydroeletrolitic and acid-basic imbalances the horses affected by colic syndrome arrived at the veterinary hospital (HV) of the UFCG. Ten animals from the hospital routine were used. The animals were divided in two groups according to age, group 1 (G1) of 0 to 3 years and group 2 (G2) over 3 years, within this age group, aspects such as degree of dehydration, sex and management nutritional. In the experiment, the animals treated in HV were submitted to a clinical, the 5 ml of venous blood from the external jugular vein was collected by a heparinized syringe. The collected blood was sent for analysis in the hemogasometer and electrolytic analyzer. The pH, Pco2, Po2 and bicarbonate results were collected. Plasma was frozen and the values of sodium, potassium, chlorine and calcium were evaluated. We observed that 70% of the animals presented hyponatremia, 30% hypokalemia, 30% hypocalcemia and 20% hypochloremia. A predisposing factor was age, since 60% of the affected animals presented above 3 years. In relation to feeding management, all animals were submitted to feeding on a basis of forage and concentrated. In the acid-base balance evaluation, all the animals presented within the reference range. However, compression colic which has been more prevalent has been shown to be a cause of innumerable Changes. Therefore, we conclude that a laboratory evaluation of horses affected by acute equine abdomen (colic syndrome) is indispensable for directing adequate treatment since hydroelectrolytic changes were commonly found, despite the absence of acid-base disturbances.
