Prematuridad Y Parámetros Clínicos De No Viabilidad En Un Potro Neonato: Reporte De Caso.

Abstract

Milagros' son was born on August 15, 2025. He is a 21.3 kg Colombian Criollo colt with a dun coat. Birth occurred at 5:30 a.m. at a gestational age of 9 months, triggered by a case of SAA. The colt was born in the red bag and with clear signs of prematurity: absence of suckling reflex, inability to stand, bulging head, subicteric membranes, hyperemic tongue, hypothermia (36.3 °C), tremors, cold extremities, depression, hyperesthesia, enophthalmos, increased range of motion, and respiratory distress with bilateral crackles and wheezes. He also presented with hypoglycemia and hyperlactatemia. Paraclinical tests and complementary studies were performed (blood glucose, lactate, abdominal, thoracic, and umbilical ultrasound, and carpal radiographs). The results showed marked leukopenia, hyperfibrinogenemia, persistent hypoglycemia, and hyperlactatemia. Thoracic ultrasound revealed a comet-tail pattern with areas of consolidation, and radiographs confirmed grade I incomplete ossification of the carpal bones. Treatment included continuous oxygen therapy, incubation, inotropes, maintenance fluid therapy, milk replacers, corticosteroids, blood transfusion, free radical scavengers, and anticonvulsants. Despite these measures, the findings confirmed severe prematurity with neonatal encephalopathy, conditions that seriously compromised the prognosis and justified the decision to perform humane euthanasia.
