BLOQUEIO DO PLEXO BRAQUIAL EM CÃES: estudo anatômico

Abstract

Associated with the advancement of science, animal welfare and the growing development in the type and severity of surgical interventions, anesthesia has necessarily evolved in a qualitative way, that is, techniques have been developed and improved to allow more invasive and painful surgical interventions to be carried out. With this, multimodal analgesia is being used more and more, and one of the techniques to potentiate analgesia is regional block, which consists of perineural application of anesthetics in low doses and, consequently, with less toxic effects. Thus, there is a need for prior planning and individualized anesthetic protocol, which controls pain in a preemptive and multimodal way, promoting a better and faster recovery in the postoperative period and reducing the extremely harmful psychological effects that can occur if pain develops. chronic. The brachial plexus block provides analgesia to the thoracic limb, being useful for pain management, and can be performed by the paravertebral, subscapular and axillary approach. When a higher block is needed, as in the case of thoracic limb amputations, paravertebral block can be chosen, thus promoting adequate analgesia for procedures involving the scapular region. The traditional approach to brachial plexus blocks is performed at the level of the scapuloumeral joint, and only anesthetizes the distal part of the humerus and beyond. This work had as main objective to review, through the main literature, the aspects related to the brachial plexus block technique in dogs.
