Anestesia de nervos do plexo braquial dos animais domésticos: uma abordagem neuroanatômica, farmacológica e técnica.

Abstract

Due to the emergence of new techniques and formulation of new anesthetic drugs, increased interest in regional anesthesia by veterinarians because they are always in search of anesthetic protocols becoming safer, with greater efficacy and with less deleterious effects. The aim was to compile information about the topography of nerves that make up the brachial plexus of the domestic animals, with their areas of innervation, the main techniques of nerve block of the plexus and major anesthetic drugs used. We described the blocking techniques regional as multiple injections in dogs and other techniques perineural in horses and ruminants, the characteristics of the drugs used as anesthetics lidocaine and bupivacaine, and also drugs that are being introduced into these procedures and risks of these techniques in domestic animals studied. Therefore, this study gave a further clarification in relation to anatomy, key techniques and anesthetics used for brachial plexus block in domestic animals, allowing application in surgical practice and, consequently, changes in the procedures and techniques, providing more safety during anesthesia.
