ABSTRACT:The experiment assessed the cardiorespiratory and hemogasometric profiles in female cats under sevoflurane resulting from the administration of tramadol. Twenty clinically healthy adult female cats separated equally into two groups: control group (CG) and tramadol group (TG) were sedated with intramuscular acepromazine (0.05 mg/kg), followed by anesthetic induction intravenous propofol (5mg/kg). After endotracheal intubation, animals were maintained on sevoflurane in oxygen administered using a non-rebreathing (Baraka) circuit. The oxygen flow-rate was maintained at 2 L per minute. Fifteen minutes after induction, either 0.05 ml/kg 0.9% saline solution or 2mg/kg tramadol were administered, both intramuscularly, to the animals in CG and TG, respectively. The period of time immediately previous to these administrations was considered as moment zero (T0). The variables were again measured 15 minutes later (T15) and subsequently in 15 minute intervals for a total of sixty minutes (T30, T45 and T60). The results were statistically evaluated through variance analysis of repeated measures (ANOVA) followed by a Tukey test or Student t-test with the nullity hypothesis rejection level set to p<0.05. The use of tramadol reduced cardiac frequency (CF), systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and mean arterial pressure (MAP). There was a reduction of the respiratory frequency (RF) and an elevation of the PaCO 2 . The body temperature (ºC) lowered in both groups throughout the experiment. The results allow us to conclude that tramadol in cats anesthetized with sevoflurane does not undergo significant cardiorespiratory and blood-gas changes, although there are significant differences in some parameters between groups, all results remained within feline standard physiological values.
Background: Uterine prolapse is an obstetric emergency because the exposed tissue can present edema, devitalization or even gangrene, depending on the evolution time and on the severity of circulatory changes. Haemorrhage due to the rupture of ovarian or uterine vessels can evolve rapidly to hypovolemic shock. More rarely, secondary thromboembolism to the uterine strangulation can be developed, complication that can also lead to death. This study reports the case of a Brazilian Molosser bitch treated by reducing total uterine prolapse, complemented with hysteropexy, in order to prevent recurrence and maintain its reproductive ability. Case: A 5-year-old Brazilian Molosser bitch was attended presenting double firm and tubular mass protruding through the vulva. The patient gave birth to five live pups, the last two of which needed to be pulled. Two days after parturition, she had abdominal contraction when a mass protruded from the vagina. A total uterine prolapse was diagnosed, since both uterine horns were found exposed and inverted, with exposition of the endometrium and the areas of placental implantation, together with the body of the uterus. The tissue was apparently edematous and lightly parched, with the presence of strange bodies, but without signals of circulatory complications or lacerations. Due to interest of the guardian in preserving the reproductive ability, an internal reduction via ventral medial celiotomy and the fixation of the uterus in the lateral abdominal wall (hysteropexy) was chosen in order to diminish the possibility of relapse in future parturition. Discussion: The definitive treatment of the uterine prolapse can be realized through ovariohysterectomy when the exposed uterine tissue is highly compromised or there is vessel rupture or no reproductive purpose for the female. The amputation of everted tissue through the vulva is also an option, but the risk of intracavitary bleeding during tissue resection must be considered when the uterine and ovarian artery and vein escape to the interior of the abdomen without according hemostasis. In cases which there are no complications of the prolapsed tissue and is desired to maintain the reproductive ability of the female, the internal reduction with hysteropexy is recommended. As the etiology of the uterine prolapse is a condition bound to several factors, between them multiple pregnancies, relaxation of the uterine ligaments and genetic factors, conditions which can be associated to the cause of the prolapse in the mentioned patient, the hysteropexy was preferred as a complementary technique to uterine preservation and prevention of the prolapse relapse in a possible new parturition. In this case, the reduction of prolapse followed by hysteropexy was preferred, because the female dog was apparently well, without signs of complication of the prolapsed tissue and with satisfactory preoperative evaluation. Adding these to the request of the guardian in maintaining the reproductive ability of the female, since the procedure would not pose as a life...
345Pesq. Vet. Bras. 29(4): 345-352, abril 2009 RESUMO.-Devido ao crescente uso dos aloenxertos nas cirurgias ortopédicas, há a necessidade do conhecimento de suas características biomecânicas ao longo do tempo de preservação. O presente trabalho consistiu na aná-lise da força de resistência à micro-tração de amostras de ossos corticais de coelho preservadas em diversos meios por até 180 dias e a fresco. Os resultados revelaram que a resistência e o tempo de preservação apresentaram uma relação inversamente proporcional, significando que, quanto maior o tempo de preservação, menor a resistência física avaliada no ensaio biomecânico de resistência à micro-tração. Dos meios utilizados, a glicerina Due to the increasing use of cortical bone allografts in orthopedic surgeries, de knowledge of its biomechanics characteristics during preservation time is needed. The present study consisted in the analyses of the resistance power to the micro-traction of samples of rabbit cortical bones preserved in several means for up to 180 days and fresh. The results showed that the resistance and the preservation time presented an inversely proportional relation, meaning that, the longer the time of preservation, the shorter the physical resistance evaluated in the biomechanical rehearsal of resistance to the micro-traction. The glycerin has presented lower values in relation to the resistance test, showing, after 30 days, only 24.58% of the present power in the fresh bone, and by 180 days, 1.76%. The samples submitted to autoclavation also showed low values by the end of the experiment, while they remained with just 12.31% of the power present in the fresh bone. The bones preserved in homologous plasma, Dakin liquid and the ones cryopreserved showed the best levels of resistance at the end of the experiment, remaining, respectively with 82.47, 70.34 and 66.72% of the maximum power, while compared with the resistance of the fresh bones. The conclusion is that the choice of methodology and time of preservation interfered directly in the biomechanics of the cortical bones, promoting decrease of the resistance capacity to the traction along the period of preservation.
Background: Perineal hernia is a serious disease characterized by weakening or atrophy and separation of the muscles and fasciae of the perineal musculature, followed by the caudal displacement of pelvic and abdominal organs to the perineum region. Treatment is invariably surgical and several approaches have been proposed, but complication and recurrence rates remain high. This study aimed to evaluate 120 cases of perineal hernia treated at the Veterinary Hospital of Uberaba (HVU) from 2005 to 2020, addressing the clinical and surgical aspects and the postoperative period, seeking to identify the most relevant factors to improve care and treatment of future patients affected by this disease.Materials, Methods & Results: The medical records of dogs with a definitive diagnosis of perineal hernia were collected. The prevalence of perineal hernia was calculated. Data were obtained regarding sex, being castrated or not, age, body mass, race, clinical signs, affected side, possibility of hernia reduction, treatments used, associated pathologies. Of the 120 cases, only 69 underwent surgery at the HVU and from these cases data were obtained regarding hernia content, surgical techniques, surgical wires used, recurrences and postoperative complications. Fisher's exact test was applied to assess the influence of the type of surgical treatment and surgical thread on the occurrence of complications and recurrences. Perineal hernia was the second most frequently observed hernia. Mixed breed, male, non-neutered and geriatric dogs were the most affected. The most frequently observed clinical signs were related to the digestive and urinary tract, consistent with the most commonly found hernia contents (bladder, prostate and rectum). The simple herniorrhaphy technique was the most used and showed a high number of complications. The second most used technique was the elevation of the internal shutter, which proved to be more efficient than the simple technique. Regardless of the technique used, the association of two or more techniques proved to be more efficient to reduce major complications. The use of the vaginal tunic stood out because it proved to be efficient in the treatment of perineal hernias regardless of whether it is associated with simple herniorrhaphy or obturator elevation. The surgical fixations of abdominal organs (Bladder, Ducto deferente and Colon) proved to be effective, since there were no recurrences or major complications associated with their use and the most used threads for herniorrhaphy were polyamide and catgut. Low recurrence rates were found in patients who received synthetic yarns. The most frequent complications were suture dehiscence and serous secretion.Discussion: Perineal hernia is a very important alteration due to difficulties in treatment, high rates of complications and recurrence, in addition to the large number of affected dogs. Several surgical techniques have already been proposed for the treatment of perineal hernia in dogs and are based on the reconstruction of the perineal musculature through sutures, muscle flaps, biological membranes, synthetic mesh and the reduction of pressure on the perineum through the surgical fixation of organs abdominals such as colon, vas deferens and bladder (in the musculature of the abdominal wall). It is concluded that the perineal hernia affects mainly male, non-neutered and geriatric dogs, being rare in females. Regardless of the techniques used, the association of two or more techniques is more efficient to reduce the rate of recurrences and complications. The autogenous vaginal tunic is a good option for muscle strengthening in perineal herniorraphies. The use of synthetic surgical wires leads to better results in the treatment of perineal hernia when compared to biological wires.

RESUMO:Os paragangliomas ou quimiodectomas são neoplasias de quimiorreceptores, de crescimento lento e de comportamento frequentemente benigno, que ocorrem na base do coração, são incomuns, podendo ocorrer em cães e raramente em gatos e bovinos. A avaliação radiográfica e ultrassonográfica contribuem no diagnóstico do paraganglioma de corpo aórtico e carotídeo em cães, sendo necessárias maiores investigações semiológicas devido aos sinais clínicos inespecíficos. O Objetivo do presente artigo é relatar a ocorrência de paraganglioma de corpo aórtico e carotídeo em cães no período de 2004 a 2015 no hospital veterinário da Universidade de Uberaba, destacando-se os sinais clínicos, raça, idade, sexo e presença de metástases. Em um total de 225 exames histológicos de coração e vasos da base cardíaca realizados neste período, cinco cães (2,22%) foram diagnosticados como portadores de paraganglioma, sendo que duas (40%) eram fêmeas e três (60%) machos. A idade média de ocorrência foi de 10,4 ± 4,72 anos, não sendo observada uma predileção racial. Os paragangliomas de corpo aórtico representaram quatro (80%) dos tumores, enquanto os de corpo carotídeo representaram apenas um (20%). Os sinais clínicos foram variáveis por estarem relacionados com a compressão vascular local, com o comprometimento dos órgãos afetados e pela congestão venosa, com consequente aumento da pressão hidrostática e extravasamento de líquido para a cavidade torá-cica. Salienta-se que em um cão desenvolveu metástase hepática. Apesar da ocorrência incomum o paraganglioma deve ser incluído na lista de diagnósticos diferenciais de cardiopatia em cães.

PREVALENCE, CLINICAL SIGNS AND ANATOMIC-PATHOLOGICAL ASPECTS OF AORTIC AND CAROTID BODY PARAGANGLIOMAS IN DOGSABSTRACT: Paragangliomas or chemodectomas are uncommon slow-growing chemoreceptor neoplasms, often benign, which appears at the base of the heart. They may occur in dogs, but rarely in cats and cattle. Radiographic and ultrasound evaluation contribute to the diagnosis of paraganglioma in canine aortic and carotid body tumors, requiring further semiological investigation due to nonspecific clinical signs. The purpose of this article is to report the occurrence of canine aortic and carotid body paraganglioma tumors from 2004 to 2015 at the Uberaba University Veterinary Hospital, highlighting the clinical signs, breed, age, sex and presence of metastases. From a total of 225 histological examinations of heart and cardiac base vessels performed in this period, five dogs (2.22%) were diagnosed as having paraganglioma, with two (40%) being female and three (60%) male. The mean age of occurrence was 10.4 ± 4.72 years, and...
RESUMO Tumores originados no sistema nervoso periférico não são comuns na clínica veterinária e seu diagnóstico é difícil. Por ser uma patologia de curso lento e insidioso muitos profissionais demoram a suspeitar dos tumores de plexo braquial, retardando muito o diagnóstico e tratamento. Os sinais clínicos observados são claudicação, dor à palpação axilar, monoparesia e, em casos mais graves, com infiltração neoplásica na medula espinhal, o paciente pode apresentar tetraparesia. Foi atendida uma cadela fox paulistinha com 10 anos de idade apresentando tetraparesia não ambulatória. O exame clínico foi sugestivo de uma lesão de medula espinhal (C6-T2), suspeitando-se de doença do disco intervertebral ou neoplasia medular. A mielografia foi realizada e mostrou compressão caudal a C6. O animal foi então submetido à hemilaminectomia para descompressão, sendo observada infiltração neoplásica das raízes nervosas na medula espinhal impossível de ser resseccionada. O paciente foi eutanasiado. O plexo braquial, os nervos espinhais e a medula foram colhidos e enviados para exame histopatológico, confirmando-se o diagnóstico de tumor maligno de bainha de nervo periférico (TMNP). O presente relato mostrou um caso cujo curso clínico da doença foi atípico, dificultando o diagnóstico. Conclui-se que sempre se deve considerar a possibilidade de neoplasias de plexo braquial em pacientes com histórico de claudicação crônica de membros torácicos não responsiva a repouso e anti-inflamatórios. Palavras-chave: neoplasia do sistema nervoso periférico, tumores, shwanoma maligno.
RESUMO:O objetivo deste trabalho foi caracterizar o perfil hematológico de cães reagentes para Leishmania spp atendidos no Hospital Veterinário de Uberaba -MG. Foram coletadas amostras de sangue de 15 cães sororreagentes nos testes de Imunofluorescência Indireta e ELISA para realização do hemograma. Dos quinze cães, 12 (80%) eram fêmeas, 53,33% (n=9) tinha idade acima de 8 anos, enquanto que a raça de maior prevalência foi a sem raça definida com 6 animais (40%). O achado mais frequente no eritrograma foi a anemia (53,3%) (n=8). Destes animais, 75% (n=6) apresentaram anemia normocítica-normocrômica. Os níveis plasmáticos de proteínas totais estavam aumentados em 8 dos 15 (53,33%) cães. A leucometria mostra que 03 (20%) cães apresentaram leucopenia e 02 (13,3%), leucocitose. A avaliação diferencial dos leucócitos destes animais revelou neutrofilia em 3 (20%) e neutropenia em 02 (13,33%), desvio para a esquerda em 03 (20%), monocitose em apenas 01 (0,66%), eosinopenia em 08 (53,33%) e linfopenia em 03 (20%). Conclui-se que no presente estudo prevaleceu o quadro de anemia, hiperproteinenia e eosinopenia na avaliação do hemograma de animais soropositivos para LVC. A análise valores do perfil hematológico obtidos dos animais estudados auxiliam o diagnóstico da LVC.
