Bloqueio perineural em membro torácico de equinos para diagnóstico de claudicação

Abstract

ABSTRACT

INTRODUCTION: Lameness is a very common syndrome in equine clinics, and can be associated with several disorders, which promote a loss of well-being as well as being unusable for work, thus resulting in economic loss. Perineural block is a technique that has multiple indications, both for therapeutic purposes and as a diagnostic tool, used to help evaluate lameness, injecting local anesthetic close to the innervation of the region to be examined. Blocks should always start from the distal to the cranial portion, until the lameness ceases and the site of the painful process is identified. OBJECTIVES: The objective of this work is to address perineural block techniques in clinical practice in horses and the factors that interfere with the performance of these procedures, such as limitations and effectiveness along with the analysis of local anesthetics applied during infiltrations. METHODOLOGY: In carrying out this study, a Literature Review was used, with a qualitative approach to the data. To carry out this review, scientific articles were used, consulted in databases such as Scielo and Google Scholar, between the years 2009 and 2023, using the descriptors anesthetic block, horses, lameness and distal portion. RESULTS: 79 articles were found, and those that did not correspond to the formulated inclusion criteria were eliminated (n= 71), resulting in a sample of 8 articles, between the years 2009 and 2023 FINAL CONSIDERATIONS: Lameness continues to be a very common syndrome in the clinic, in which the animal loses its well-being and can also be rendered unusable for work. The use of perineural blocks is a cheap and simple alternative for assistance in the clinic as well as for surgeries, it is a low-cost anesthesia that is easy to apply in field conditions.
