As claudicações são as afecções que mais afastam equinos dos dias de treinamento e competições esportivas, sendo os membros torácicos os mais acometidos. Apesar do grande avanço na medicina esportiva equina, a analgesia de diagnóstico provavelmente se mantém como uma das ferramentas mais valiosas na identificação da claudicação, com resultado claro e imediato. Muitos casos acabam evoluindo às enfermidades degenerativas crônicas, que tornam-se não responsivas às condutas clínico - cirúrgicas terapêuticas tradicionais, sendo indicado o uso de fármacos ou procedimentos cirúrgicos que promovam a analgesia paliativa “irreversível” ou reversível prolongada, através da interrupção da condução nervosa à região (neurólise). O nervo digital palmar/plantar é o mais submetido à técnica, pois os índices de perda proprioceptiva são mínimos, porém existe a informação de que quanto mais proximal o bloqueio analgésico perineural, maior o déficit motor ocasionado. Visto a escassez de informações sobre estes riscos, este trabalho objetivou realizar a avaliação postural de equinos submetidos aos bloqueios anestésicos com bupivacaína dos nervos palmares, metacárpicos palmares, ulnar, mediano e músculo cutâneo, de forma isolada e em tempos diferentes, buscando identificar possíveis disfunções motoras associadas ao nervo submetido ao bloqueio. Foram avaliados 7 equinos adultos hígidos, sem problemas locomotores e trotadores, em forma de triplicata, em relação aos seguintes testes de reação postural para o membro torácico esquerdo (M.T.E.): Prova de Dorso-flexão do Membro (PDF); Prova de Cruzamento do Membro (PCM); Prova de Deslizamento (PD) e Prova de Obstáculos após bloqueio anestésico perineural com bupivacaína 0,5 %. Concluiu-se que equinos submetidos a bloqueios anestésicos a partir do nervo metacárpico palmar apresentam déficits proprioceptivos que podem pôr em risco a vida do conjunto cavalo/cavaleiro, devendo o uso de agentes neurolíticos serem evitados em equinos atletas em atividade.

Lameness is the condition that most distances horses from training days and sports competitions, with the thoracic limbs being the most affected. Despite the great advances in equine sports medicine, diagnostic analgesia probably remains one of the most valuable tools in identifying lameness, with clear and immediate results. Many cases end up evolving into chronic degenerative diseases, which become unresponsive to traditional therapeutic clinical - surgical procedures, indicating the use of drugs or surgical procedures that promote “irreversible” palliative or prolonged reversible analgesia, through interruption of nerve conduction to the region (neurolysis). The palmar/plantar digital nerve is the most submitted to the technique, as the rates of proprioceptive loss are minimal, but there is information that the more proximal the perineural analgesic block, the greater the motor deficit caused. Given the scarcity of information about these risks, this study aimed to perform the postural assessment of horses submitted to anesthetic blocks with bupivacaine of the palmar, palmar metacarpal, ulnar, median and cutaneous muscle nerves, in isolation and at different times, seeking to identify possible dysfunctions associated with the nerve undergoing blockade. Seven healthy adult horses, without locomotor and trotting problems, were evaluated in triplicate, in relation to the following postural reaction tests for the left forelimb: Limb Dorsiflexion Test (PDF); Member Crossing Test (PCM); Sliding Test (PD) and Obstacle Test after perineural anesthetic block with 0.5% bupivacaine. It was concluded that horses submitted to anesthetic blocks from the palmar metacarpal nerve present proprioceptive deficits that can endanger the life of the horse/rider as a whole, and the use of neurolytic agents should be avoided in active athletic horses.

RESUMO -Objetiva-se relatar o caso de um garanhão da raça Quarto de Milha de 12 anos, portador de síndrome degenerativa crônica podal e anquilose parcial na articulação metacarpo-falângica do membro torácico esquerdo, submetido à neurólise química palmar com cloreto de amônio 2%, exteriorizando eficácia analgésica e retorno à atividade esportiva por 40 dias. Após o período, foi realizado neurectomia palmar (NP), sendo que com 110 dias o equino apresentou neuromas dolorosos, sendo submetido à nova cirurgia. Há necessidade de mais relatos e pesquisas envolvendo a NP em equino avaliando: tempo e qualidade de analgesia; complicações após NP; reais riscos proprioceptivos ao animal e avaliação de fatores de risco na formação de neuromas.Palavras-Chave: Quarto de Milha; neurólise; cloreto de amônio; neuroma doloroso. ABSTRACT -The aim is report the case of a stallion Quarter Horse with 12 years old, with podal chronic degenerative syndrome and partial ankylosis in metacarpal-phalangeal joint of the left forelimb, submitted to palmar chemical neurolysis with ammonium chloride 2 % , externalizing analgesic efficacy and return to sports activity for 40 days. After the period, was performed palmar neurectomy (NP), and with 110 days the horse had painful neuromas, underwent the new surgery. It is necessary to more reports and research involving the NP in equine evaluating: time and quality of analgesia; complications after NP; proprioceptive real risks to the animal and assessment of risk factors in the formation of neuromas.

The aim of this research was to evaluate the analgesia provided by red propolis and Mikania glomerata oral administration in 40 female dogs submitted to ovariohysterectomy (OH) compared to standard treatment with no steroidal anti-inflammatory ketoprofen. Through of a doble-blind and randomized study, the animals were divided in four different groups with 10 animals of treatments: control treatment with ketofen (CT), propolis treatment (PT), Mikania glomerata treatment (MT), and propolis-Mikania glomerata treatment (PGT). All pacients received one of these treatments two hours before OH and the pain evaluation was performed 1 (T1), 6 (T6), 12 (T12), and 24 hours (T24) after OH using University of Melbourne Pain Scale and the Glasgow Composite Measure Pain Scale. Glucose levels were also measured at the same times, except at 6 hours after OH (T6). All treatments achieved similar and satisfactory analgesia. During the experiment, only three animals were rescued, two belonging to the PT and another of the MT. Considering the lower rate of complications and no rescue necessity of in PGT and CT treatments, they were considered the most effective and safer. The combined treatment with propolis and Mikania glomerata could  be a promising alternative method for OH surgery analgesia in bitches.
