BLOQUEIO DE NERVOS PERIFÉRICOS DISTAIS EM BOVINOS: ABORDAGEM ANATÔMICA APLICADA AOS MEMBROS TORÁCICOS E PÉLVICOS

Abstract

The deepening of studies in animal anatomy is essential for the veterinary doctor to develop the skill of recognizing small-sized anatomical structures, such as peripheral nerves, which are fundamental for the precise execution of anesthetic and surgical procedures. This study aims to analyze the importance of anatomical description applied to distal peripheral nerve blocks in cattle, addressing the thoracic and pelvic limbs, and to discuss how the lack of this information can compromise the precision and efficacy of anesthetic techniques in the field. It also aims to describeand topographically reference the distal peripheral nerves of the thoracic and pelvic limbs in cattle, emphasizing their importance for the clinical application of perineural analgesia. Anatomical specimens fixed using the modified Larssen technique and the traditional 10% formaldehyde technique were utilized, allowing for the comparison of tissue preservation and facilitating dissection and anatomical documentation. The analysis demonstrated that the lack of objective and applied anatomical information can compromise the precision and efficacy of blocks under field conditions. As a final product, a technical guide was prepared, based on the topographic relationship between nerves and block points. The study contributes significantly to clinical practice, improving safety, efficacy, and animal welfare.
