Abstract
El cólico es la causa más importante de muerte en el caballo y hasta un 17% de los individuos que lo padecen requieren tratamiento quirúrgico. Este tratamiento tiene un coste económico y emocional importante para el propietario por lo que el veterinario debe poder ofrecer un pronóstico en referencia al riesgo de mortalidad del caballo en el periodo perioperatorio. La identificación de los factores de riesgo de mortalidad así como los modelos predictivos desarrollados hasta el momento han demostrado su utilidad y están basados principalmente en el análisis de variables preoperatorias clínicas y laboratoriales y quirúrgicas intraoperatorias. Estos estudios destacan un aumento del riesgo de muerte asociado al compromiso cardiovascular, la duración de la cirugía y la patología. Hasta el momento no se han realizado estudios que tengan en cuenta como posibles factores de riesgo los parámetros monitorizados en el procedimiento anestésico. Estos parámetros presentan ventajas que incluyen una mayor precisión, ya que su medición no depende del criterio subjetivo de un observador, y que describen el estado cardiovascular y ventilatorio del paciente que, como se ha comprobado en el periodo preoperatorio, son factores de riesgo de mortalidad en caballos operados de cólico. Además los modelos pronósticos de mortalidad desarrollados tampoco han tenido en cuenta dichas variables anestésicas...
Colic is the leading cause of death in horses and up to 17% of the individuals who suffer require surgical treatment. This treatment has an important economic and emotional cost of ownership so the veterinarian should be able to offer a prognosis of the risk of mortality in the perioperative period. The identification of risk factors for mortality and predictive models developed so far have proved their usefulness and are based mainly on the analysis of preoperative clinical and laboratory, and perioperative surgical variables. These studies highlight an increased risk of death associated with the cardiovascular status, duration of surgery and pathology or disease problem causing the colic. So far there have been no studies that consider, as potential risk factors, the parameters monitored in the perianaesthetic period. These parameters have advantages including greater precision, since its measurement does not depend on the subjective judgment of an observer, assessing the cardiovascular and ventilatory status of the patient, already considered risk factors in the preoperative period. Also prognostic mortality models developed have not taken into account variables such those gathered during the anaesthetic period...
