RELATÓRIO DE ESTÁGIO CURRICULAR SUPERVISIONADO E TRABALHO DE CONCLUSÃO DE CURSO: BLOQUEIO DO PLEXO BRAQUIAL GUIADO POR ULTRASSONOGRAFIA EM CÃO - RELATO DE CASO

Abstract

In Veterinary Medicine, it is common to come across bone fractures, in which, normally, the treatment instituted to reduce the fracture is surgical. In order to obtain effective analgesia and minimize the adverse effects of the drugs used in the anesthesia of patients undergoing orthopedic surgeries, it is recommended the application of drugs of different pharmacological classes and the use of different anesthetic techniques. The objective was to report the use and analgesic efficacy of brachial plexus block, performed by the subscalene approach guided by ultrasound, when applied in surgery for osteosynthesis of the humerus in a dog. Therefore, a case of a five-year-old male canine weighing 8.3 kg was reported, which was diagnosed with humerus fracture. The recommended treatment was osteosynthesis of the humerus. The animal was submitted to general inhalation anesthesia and as an analgesic technique, brachial plexus block was performed using 5% bupivacaine. The analgesic efficiency of the blockade was verified by monitoring the animal's physiological and behavioral parameters during the trans and post-surgical period. It is concluded that subscalene brachial plexus block in dogs provides excellent analgesia at the surgical site, presenting itself as easy to perform when performed under ultrasound guidance by a trained professional.
