2.1.1 Clinical presentation
A 7-day-old Percheron colt was presented for evaluation of pyrexia and wet umbilicus. The colt was febrile (39.40C; reference range: 37.5-38.60C), but bright, alert, and responsive. The remainder of his vital parameters were within normal limits. The umbilicus was moderately enlarged, with no heat, pain or discharge appreciated.
Ultrasonographic evaluation revealed moderately enlarged umbilical arteries and urachus with an abscess at the caudal aspect of the umbilicus. Measurements of the umbilical remnants were not recorded. A complete blood count revealed mild leukocytosis (17,050 cells/uL; reference range: 5-12 x103/uL) characterized by neutrophilia (15,580 cells/uL; reference range: 2.18-6.96 x103/uL).
Umbilical surgical excision was recommended and elected by the owner. Pre-operative ceftiofur sodium (5 mg/kg, intravenously, q 12 hours), flunixin meglumine (1.1 mg/kg, intravenously, q 24 hours) and omeprazole (1 mg/kg, orally, q 24 hours) were administered.
