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.
