Pharmacological treatment of aural hematoma in a dog

Abstract

Auricular hematoma is defined as an increase in subcutaneous volume, there is usually blood in the auricle secondary to a rupture of the capillaries producing a separation of the auricular cartilage and the skin. It is generally observed unilaterally or bilaterally in patients with a history of otitis or alteration of the coagulation factors. We present the 1clinical case of a 12-year-old domestic dog, Labrador breed, with a history of an increase in volume of the right ear for 8 days. In the general physical examination, serum was observed an increase in the volume of fluid in the auricle. The corresponding blood tests were performed with normal ranges, and the study of hemoparasites was negative. Triamcinolone 0.2 mg/kg was started as a single dose in the affected area after draining approximately 5 mL of bloody fluid. The dog was sent home with serratiopeptidase 1 mg/kg every 24 hours for 10 days. The dog was checked 8, 21 and 90 days after treatment, showing 90% improvement and mild fibrosis in the atrium. No further treatment with corticosteroids was applied. The use of corticosteroids with fibrinolytics is a good treatment option of auricular hematoma.
