Los potros neonatos son susceptibles a enfermedades potencialmente mortales. Por tanto, es importante identificar marcadores que permitan predecir la supervivencia de estos pacientes, e iniciar el tratamiento adecuado para cada caso. Este estudio fue realizado en el Centro de Perinatología Equina Foal Care ubicado en Cajicá, Cundinamarca. Se revisaron y analizaron las historias clínicas de 106 potros que ingresaron a hospitalización entre septiembre de 2019 y diciembre de 2020 para evaluar el valor predictivo de los parámetros de gases sanguíneos y electrolitos frente a la supervivencia de potros neonatos hospitalizados. Se utilizaron diferentes pruebas estadísticas como la prueba de Kolmogorov Smirnov, U de Mann-Whitney, regresión logística binaria, pruebas de chi cuadrado, odds ratio y análisis de la curva de características del operador del receptor (ROC). Se observó que el desorden ácido-básico más común al ingreso a hospitalización fue la acidosis metabólica (37/106), y el desequilibrio electrolítico más frecuente fue la hipocalcemia (89/106). La variable más significativamente relacionada con la supervivencia fue el pH > 7,35 (p = ,007; OR = 0,288; IC = 95 %, 0,117-0,706). Los factores de riesgo asociados con la no supervivencia de los potros fueron pH < 7,35, lactato > 4,5 y glucosa < 119,5 mg/dl.

Horses, due to their unique anatomy and physiology, are particularly prone to intraoperative cardiopulmonary disorders. In dorsally recumbent horses, chest wall movement is restricted and the lungs are compressed by the abdominal organs, leading to the collapse of the alveoli. This results in hypoventilation, leading to hypercapnia and respiratory acidosis as well as impaired tissue oxygen supply (hypoxia). The most common mechanisms disturbing gas exchange are hypoventilation, atelectasis, ventilation–perfusion (V/Q) mismatch and shunt. Gas exchange disturbances are considered to be an important factor contributing to the high anaesthetic mortality rate and numerous post-anaesthetic side effects. Current monitoring methods, such as a pulse oximetry, capnography, arterial blood gas measurements and spirometry, may not be sufficient by themselves, and only in combination with each other can they provide extensive information about the condition of the patient. A new, promising, complementary method is near-infrared spectroscopy (NIRS). The purpose of this article is to review the negative effect of general anaesthesia on the gas exchange in horses and describe the post-operative complications resulting from it. Understanding the changes that occur during general anaesthesia and the factors that affect them, as well as improving gas monitoring techniques, can improve the post-aesthetic survival rate and minimize post-operative complications.
