Enucleação subconjuntival em um gavião / Subconjuntival enucleation in a Hawk

O gavião-asa-de-telha (Parabuteo unicinctus) é uma ave de rapina que possui ampla distribuição em todo o território nacional. As aves de rapina desenvolveram uma visão tão eficiente que as puseram num patamar diferenciado em relação às outras espécies. No entanto, isso as tornou extremamente sensíveis às afecções oftálmicas, como malformações, inflamações, infecções, degenerações, neoplasias, distúrbios nutricionais e lesões traumáticas. Diante disso, este trabalho apresenta um relato de caso que descreve um gavião-asa-de-telha (Parabuteo unicinctus) adulto, fêmea, pesando 0,800kg, cujo a principal queixa é o olho esquerdo buftálmico e com coloração acinzentada. Este quadro clínico suscitou na remoção do olho pela técnica de enucleação subconjuntival lateral, sendo essa manobra a única forma de interromper o estímulo doloroso e a infecção. Por conseguinte, o trabalho demonstrou a importância e a exequibilidade da técnica correta de enucleação em aves de rapina, de modo a permitir a manutenção da espécie e minimizar os riscos de extinção.

The Harris' hawk (Parabuteo unicinctus) is a bird of prey that has a wide distribution throughout the national territory. Birds of prey have developed such an efficient vision that they are on a different level compared to other species. However, it made them extremely sensitive to ophthalmic conditions, such as malformations, inflammations, infections, degenerations, neoplasms, nutritional disorders, and traumatic injuries. Thus, this work presents a case report that describes an adult female Harris' hawk (Parabuteo unicinctus), weighing 0.800kg, whose main complaint is the left eye buphthalmic and with a grayish color. This clinical condition led to the removal of the eye by the lateral subconjunctival enucleation technique, which was the only way to interrupt the painful stimulus and the infection. Therefore, the work demonstrated the importance and feasibility of the correct technique of enucleation in birds of prey to allow the maintenance of the species and minimize the risks of extinction.

Colocefalectomia para o tratamento de fratura fisária da cabeça do fêmur em pônei / Colocephalectomy for the treatment of capital physeal fracture of the femoral head in pony

Background: Femoral capital physeal fractures occur in young animals and are generally associated with trauma. They have apoor prognosis and surgical therapy is the most indicated. There are few studies describing surgical treatment and postoperative results, so the objective of the present report was to present the first case in Brazil of a colocefalectomy for the treatmentof femoral capital physeal fracture in a young pony, the post-surgical and the results obtained with the technique employed.Case: An 18-month-old pony, male, not castrated, , weighing 136 kg was referred to the Veterinary Hospital of the FederalUniversity of Paraná (HV-UFPR) with a history of trauma for 4 days. On physical examination, the animal presented lamenessgrade 5 of the right pelvic limb, shortening and lateral deviation of the limb, crackling and painful sensation on abduction, andslight atrophy of the gluteal muscles on the affected side. In the radiographic examination, a femoral capital physeal fracturewas found in the oblique ventro-dorsal projection. Once the diagnosis was performed, a colocefalectomy was realized, as thepatient is a light and short horse. The patient underwent general anesthesia and was placed in the left lateral position. The accessto the coxofemoral joint was made through the lateral face of the right hindlimb. The muscles of the region were incised anddeviated, so a partial myotomy was performed in the deep gluteal and vastus lateralis. This procedure allowed to visualize thefracture, where the head of the femur remained congruent to the acetabulum. A hammer and a curved osteotome were usedto section the round ligament, allowing the dislocation of the femoral head and with the aid of an oscillating orthopedic sawwas performed the femoral neck ostectomy. Previously to the synthesis of the muscular planes and the skin, a passive tubular...

Forelimb amputation and long-term follow-Up in a female donkey

Background: Limb amputation may be a life-saving procedure for animals and minimally impact their comfort and qualityof life, as previously reported in pets. This procedure is an appropriate alternative to euthanasia when catastrophic injury toa limb prevents its successful restoration. In horses, limb amputation has been performed for the past 40 years. Althoughin the reviewed literature there are no scientific reports of limb amputation in donkeys. This paper aimed to report a successful forelimb amputation and long-term follow-up in a female donkey.Case: A 10-month-old and 95 kg female Nordestino donkey was evaluated for a wound with bone exposition on the leftforelimb. Physical examination revealed that the donkey was alert with moderate body condition score, tachycardia, tachypnea, and a medial wound revealing the necrotic aspect of the left radius. Radiographic examination presented Salter-Harristype 1 exposed radius fracture. Hematology revealed normocytic and normochromic anemia, and hyperfibrinogenemia.Due to the catastrophic injury and no forecast for building a prosthesis, the donkey underwent general anesthesia for leftforelimb amputation through the midhumerus diaphysis. A fish-mouth skin incision was performed on the midhumerus,the underlying musculature was dissected and the vessels ligated until the bone could be accessed. Then, a sterile sawwire was used to transect it, and bone edges were rounded. Muscle and fascia were harvested with the skin to provideadditional padding at the end of the stump. Postoperatively, the donkey was submitted to broad spectrum antibiotic, antiinflammatory and analgesic therapy, and tetanus prophylaxis. Preventative treatment for overload laminitis included frogsupport pads and resting leagues on all three legs. No short-term complications were observed and the donkey made a fullrecovery. Long-term complications included fistula formation on the stump, and distal interphalangeal joint...

CONTENÇÃO QUÍMICA INTRANASAL EM MACACOS-PREGO (SAPAJUS SP.) E EM GAVIÃO- ASA-DE-TELHA (PARABUTEO UNICINCTUS)

ANDRADE, E, S. Contenção química intranasal em primatas e aves de rapina neotropicais. 2020. 109p. Tese (Doutorado em Ciência animal nos trópicos) Escola de Medicina Veterinária e Zootecnia Universidade Federal da Bahia. Várias espécies de animais selvagens são encontradas em centros de triagem e reabilitação. Entre eles, podemos citar os primatas e aves de rapina neotropicais. O manejo adequado e seguro desses animais geralmente está associado ao acréscimo de técnicas de sedação ou contenção química à terapia, pois nem sempre é possível manipular esses animais apenas com o uso de métodos de contenção física e, além disso, tais métodos físicos podem superar o nível de estresse tolerado pelas espécies em contenção. O conhecimento e o estabelecimento de parâmetros sedativos, vias de administração viáveis e seguras, bem como a avaliação de parâmetros fisiológicos, servem de auxílio norteador e imprescindível na medicina de animais silvestres, pois também são instrumentos de auxílio à avaliação clínica e ao diagnóstico de animais silvestres. Em pequenos primatas, assim como em aves de rapina, como o macaco-prego (Sapajus sp.), E o gavião-asa-de-telha (Parabuteo unicinctus), o uso de protocolos dissociativos, como o midazolam associado à dextrocetamina, por apresentarem grande eficiência, imobilidade e consequente segurança. Quando usados em combinação com a via intranasal, mostram-se uma opção viável, rápida e minimamente invasiva, em comparação com as técnicas de administração intramuscular de rotina. Ser capaz de realocar rapidamente o animal para seu recinto ou vida livre. O objetivo deste estudo foi avaliar os efeitos sedativos, cardiorrespiratórios e de temperatura, após administração de midazolam isolado ou associado à dextrocetamina por via intranasal (IN) em macacos-prego, e da mesma forma avaliar a contenção química e parâmetros cardiorrespiratórios e temperatura administração intranasal de midazolam associado à dextrocetamina em gaviões. Todos os animais apresentaram sedação ou contenção química satisfatória, com imobilidade moderada a intensa e relaxamento muscular, sem alterações significativas no comportamento ou nos parâmetros cardiorrespiratórios e de temperatura.

ANDRADE, E, S. Intranasal chemical restraint in neotropical primates and birds of prey. 2020. 109p. Tese (Doutorado em Ciência animal nos trópicos) Escola de Medicina Veterinária e Zootecnia Universidade Federal da Bahia. Several species of wild animals are found in screening and rehabilitation centers. Among them, we can mention the neotropical primates and birds of prey. Proper and safe handling of these animals is usually associated with the addition of sedation or chemical restraint techniques to the therapy, as it is not always possible to manipulate these animals only with the use of physical restraint methods and, in addition, such physical methods can overcome the level of stress tolerated by the species in contention. The knowledge and establishment of sedative parameters, viable and safe routes of administration, as well as the evaluation of physiological parameters, serve as a guiding and indispensable aid in the medicine of wild animals, since these are also instruments to aid clinical evaluation and diagnosis of sanity. In small primates, as well as in birds of prey, such as the capuchin monkey (Sapajus sp.), And the winged hawk (Parabuteo unicinctus), the use of dissociative protocols, such as midazolam associated with dextrocetamine, as they present great efficiency, immobility and consequent safety. When used in combination with the intranasal route, they prove to be a feasible, quick and minimally invasive option, compared to routine intramuscular administration techniques. Being able to quickly relocate the animal to its enclosure or free life. The objective of this study was to evaluate the sedative, cardiorespiratory and temperature effects, after administration of midazolam alone or associated with dextrocetamine intranasally (IN) in capuchin monkeys, and similarly to assess sedation and cardiorespiratory parameters and temperature intranasal administration of midazolam associated with dextrocetamine in hawks. All animals presented satisfactory sedation, with moderate to intense immobility and muscle relaxation, without significant changes in behavior or in cardiorespiratory and temperature parameters.
