Corticoterapia intralesional no tratamento de otohematoma em cães / Treating otohematomas in dogs with intra-lesional corticotherapy

Background: Otohematoma is common in dogs and is characterized by blood accumulation between the skin and cartilageof the outer ear. While the etiology is related to trauma, most cases have a predisposing condition. Treatment must drainthe hematoma and maintain appropriate skin apposition to the ear cartilage. Treatment can be surgical, but there are alsoconservative options such as puncture drainage, followed by intralesional injection of glucocorticoids. This alternativemethod is less invasive than surgery, with an equivalent success rate. This study aimed to describe intralesional injectionof corticosteroids for the treatment of dogs with otohematoma at a veterinary clinic.Materials, Methods & Results: Otohematoma was diagnosed and treated in 23 dogs (14 males and 9 females, weighing9.6 ± 2.7 kg) at a reference private veterinary clinic. The dogs were chemically restrained, and their ears were cleanedwith chlorhexidine. The lower face of each ear with otohematoma was then punctured with a needle coupled to a syringeto drain the liquid. Following drainage, the equipment was removed and the collected liquid volume was measured. A0.5 mg/kg dose of methylprednisolone acetate was prepared and diluted in saline (0.9% NaCl) to a volume equivalent to1/10 of the previously drained content volume from the otohematoma. The prepared solution was then injected into thedrained ear. Additionally, each patient was treated for the original cause of the otohematoma, according to conventionalprotocols. Eight animals (34.78%) had bilateral otohematoma and 15 (65.22%) presented with unilateral lesions. Leukocytosis was observed in most patients. Other laboratory alterations present in the studied dogs were thrombocytopenia,leukopenia, and anemia. Twenty (86.96%) patients presented with otitis externa. All patients were reassessed one weekafter the initial treatment, and 19 (82.60%) fully recovered. The remaining...

Novo método para contenção farmacológica e anestesia de campo em cães domésticos (Canis familiaris), empregando a fórmula “zad-50” (zoletil/50® + atropina + dormiun-v®) / New method for chemical restraint and field anesthesia of domestic dogs (canis familiaris) with the “zad-50” formula (zoletil/50®®+ atropine + dormiun-v®®)

Relata-se a contenção farmacológica de 30 cães domésticos (Canis familiaris) adultos, sendo 13 machos e 17 fêmeas, com massa corporal entre 2,05 e 41,5 (10,36±9,63) kg, submetidos a procedimentos cirúrgicos eletivos e de urgência. Foi usada a associação de tiletamina, zolazepam, atropina e detomidina, em doses calculadas por meio de extrapolação alométrica interespecífica. Os fármacos foram combinados numa preparação concentrada que foi denominada “ZAD-50” (Zoletil/50®+ Atropina + Dormiun-V®), para a qual se adiciona ao conteúdo desidratado de um frasco de Zoletil/50®, os volumes de 0,25 mL de atropina a 1%, 0,265mL de Dormiun-V® e 2,2mL de água destilada, obtendo-se volume final exato de 3,0 mL de ZAD-50, com os fármacos associados numa concentração que permite a contenção farmacológica de um cão de 10,0 kg com um volume de 0,6 mL, por exemplo. Esse método simplifica o trabalho veterinário em situações de rotina clínica, sendo eficiente para contenção farmacológica e anestesia de cães.AU

This paper reports the chemical restraint of 30 adult domestic dogs (Canis familiaris), being 13 males and 17 females, weighing 2.05 to 41.5 (10,36±9,63) kg, submitted to elective and urgency surgical procedures. There was employed the combination of tiletamine, zolazepam, atropine, and detomidine, in allometrically scaled dosages. The drugs were combined in a concentrate preparation called “ZAD-50” (Zoletil/50® + Atropine + Dormiun-V®), in which the dehydrated content of a Zoletil/50® vial is diluted with 0.25 mL of 1% atropine, 0.265 mL of Dormiun-V®, and 2.2 mL of distilled water, being exactly 3.0 mL the final volume of ZAD, with the drugs associated in a concentration which permits the chemical restraint of a 10.0 kg dog with a 0.6 mL volume, for example. This method simplifies veterinary duties in clinical routine, being efficient for chemical restraint and anesthesia of dogs.AU
