Resumo

JUSTIFICATIVA E OBJETIVOS: O bloqueio de plexo braquial é técnica anestésica utilizada para procedimentos em membros superiores. O plexo braquial é território potencial para absorção de anestésicos locais. Estudos dos estereoisômeros da bupivacaína vêm demonstrando menor potencial de toxicidade da fração levógira (levobupivacaína) sobre o sistema cardiovascular. Porém, é discutida a eficácia anestésica (bloqueio sensitivo e motor) da levobupivacaína em anestesia do neuroeixo. Este estudo visa demonstrar a eficácia anestésica da levobupivacaína, comparandoa com a bupivacaína racêmica em bloqueio de plexo braquial, via perivascular subclávia. MÉTODO: Cinquenta pacientes adultos de ambos os sexos, ASA I e II, foram submetidos à anestesia de plexo braquial via perivascular subclávia para procedimentos ortopédicos de membros superiores, com auxílio de neuroestimulador. Foram divididos de modo aleatório em dois grupos: G BUPI - bupivacaína racêmica e G LEVO - levobupivacaína, num volume de 30 mL a 0,5%. O bloqueio sensitivo foi avaliado pelo método de "picada de agulha" nos metâmeros de C5 a C8; e o bloqueio motor, nos intervalos em minutos 1, 2, 5, 10, 15, 20, 25, 30 ou até instalação do bloqueio em movimentos dos dedos, mão, antebraço e braço. RESULTADOS: Não houve diferença estatística entre os dois grupos quanto à latência, incidência de falhas e grau do bloqueio motor, bem como incidência de falhas do bloqueio sensitivo, mas verificou-se diferença estatística da latência do bloqueio sensitivo em todos os metâmeros analisados. Não houve efeitos adversos inerentes à aplicação do anestésico local. CONCLUSÕES: A levobupivacaína demonstrou eficácia anestésica em bloqueio de plexo braquial, equiparável à solução racêmica usualmente empregada.

Abstract

BACKGROUND AND OBJECTIVES: Brachial plexus block is used in surgical procedures of the upper limbs. The brachial plexus is a potential territory for absorption of local anesthetics. Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form (levobupivacaine). However, the anesthetic efficacy (sensorial and motor blockades) of levobupivacaine in neuroaxis blocks has been debated. The objective of this study was to demonstrate the anesthetic efficacy of levobupivacaine in brachial plexus block, using the perivascular subclavian approach, by comparing it to racemic bupivacaine. METHODS: Fifty adult patients of both genders, ASA I and II, underwent subclavian perivascular brachial plexus block, with the aid of a peripheral neurostimulator, for orthopedic surgeries of the upper limbs. Patients were randomly divided into two groups: G BUPI - racemic bupivacaine, and G LEVO - levobupivacaine, and they received 30 mL of the 0.5% solution. Sensorial blockade was evaluated by pinprick stimulation from C5 to C8 metameres; and the motor blockade was assessed 1, 2, 5, 10, 15, 20, 25, and 30 minutes after the administration of the local anesthetic or until blockade of fingers, hand, forearm, and arm movements was observed. RESULTS: Statistical differences in latency, failure rate, and degree of the motor blockade, and failure of the sensorial blockade between both groups were not observed, but the latency of the sensorial blockade in all metameres analyzed showed statistically significant differences. Adverse events inherent to the administration of local anesthetics were not observed. CONCLUSIONS: The anesthetic efficacy of levobupivacaine in brachial plexus block was similar to that of the racemic solution commonly used.
