Objective. This study aims to distinguish blood gas changes in horses with colic syndrome in which small or large intestine is affected. Materials and methods. Thirty Mangalarga Marchador horses were assessed, divided into groups according to the affected intestinal segment in episodes of colic syndrome (ECS): a group (N = 10) of horses suffering from ECS with lesions only in the small intestine, a group (n = 10) of horses suffering from ECS with lesions only in the large intestine and a group (N = 10) of healthy horses (control). All the animals with ECS were submitted to exploratory laparotomy in order to establish the intestinal segment affected. Blood samples were collected by venipuncture, before surgical procedure to determine sodium, potassium, chloride, urea, glucose, hematocrit, hemoglobin, pH, carbon dioxide partial pressure, total carbon dioxide concentration, bicarbonate, base excess and anion gap. Results. No significant changes were found in plasma levels of [Na.sup.+], [K.sup.+], [Cl.sup.-], pC[O.sub.2] and anion gap in any type of ECS. Horses with small intestine injuries presented higher levels of tC[O.sub.2], urea and bicarbonate compared to those with large intestine injuries and to the control group, as well as higher levels of glucose and base excess than the control group. Conclusions. Horses with colic syndrome bearing small intestine injuries show wider variations in the blood gas parameters than horses with large bowel lesions.

El presente estudio tuvo como objetivo diferenciar las alteraciones de gases sanguineos que ocurren en casos de colico equino con comprometimiento en intestino delgado o grueso. Material y metodos. Fueron evaluados 30 caballos Mangalarga Marchador con sindrome de colico equino (SCE) divididos en grupos segun el segmento intestinal afectado con episodios de colico: un grupo de animales (N = 10) con SCE solo en el intestino delgado, un grupo (N = 10) con SCE solo en el intestino grueso y un grupo (N = 10) de animales sanos (control). Todos los animales fueron sometidos a laparotomia exploratoria para identificar el segmento intestinal afectado. Muestras de sangre fueron recogidas antes del procedimiento quirurgico para determinar la concentracion: sodio, potasio, cloro, urea, glucosa, hematocrito, hemoglobina, pH, presion parcial de dioxido de carbono, concentracion total de dioxido de carbono bicarbonato, exceso de base y anion gap. Resultados. No fueron observadas alteraciones significativas en los niveles plasmaticos de [Na.sup.+], [K.sup.+], [Cl.sup.-], pC[O.sub.2] ni anion gap, independiente de la localizacion intestinal del SCE. Los equinos con lesiones en el intestino delgado presentaron niveles superiores de tC[O.sub.2], urea y HC[O.sub.3.sup.-] con relacion a los que tuvieron lesiones de intestino grueso y al control, asi como niveles superiores de glucosa y de exceso de base con relacion al control. Conclusiones. Equinos con sindrome de colico con lesion de intestino delgado presentaron variaciones mas amplias en los parametros de gases sanguineos que equinos con colico afectados en el intestino grueso.
