Several clinical studies on neuroaxis block have shown that the efficacy and the nloqueo of the motor blockade of levobupivacaine are similar to that of racemic bupivacainewhile others observed that the duration of its motor blockade is shorter than that of racemic bupivacaine Patients were randomly divided into two groups: In the present study, shorter latency of the braquual blockade was observed in the levobupivacaine group in all metameres evaluated, but both groups had similar incidence of failures.

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. This lack of consensus was the basis for this study, i. Supraclaivcular to cite this article. A double – blindrandomised controlled trial.

The use of levobupivacaine in brachial plexus block seems promising considering the lower toxicity and the need of large volumes. To assess the degree of the motor blockade, the following classification plexoo used: In the operating room, venoclysis was performed in the contralateral upper limb, Ringer’s lactate 10 mL.


Inclusion criteria were as follows: Topics Discussed in This Paper.

The site that triggered muscular response to a stimulus equal to or lower than 0. Skip to search form Skip to main content.

Services on Demand Journal. A double-blind, randomised controlled trial. The brachial plexus is a potential territory for absorption of local anesthetics.

On the day before the surgery, patients were informed about the study and signed an informed consent. The latency and incidence of failures were not statistically different between both groups Table II.

Local anesthetics and mode of delivery: The time between the administration of the local anesthetic and the onset of the blockade for each of the movements mentioned was recorded.

The clinical results of levobupivacaine in brachial plexus blocks, both in the present study and in the literature, indicate that latency, duration, and quality of the blockade is similar to that of racemic bupivacaine. However, the possibility of unsatisfactory motor blockade, both in neuroaxis and brachial plexus blocks, has yet to be discarded Rev Bras Anestesiol, ; A considerable number of studies on the use of levobupivacaine in subarachnoid blocks and, especially, in epidural blocks can be found in the literature.

Only two studies compared racemic bupivacaine and levobupivacaine 17,21 while the other studies in the literature compared levobupivacaine and ropivacaine 19,20 or evaluated different volumes, doses, concentrations, and routes of administration of levobupivacaine 18, Significant hemodynamic changes were not observed. However, brachial plexus blockade can set a potential place for absorption of local anesthetics and the development of systemic toxicity Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine.


Fifty adult patients of both genders, ASA I and II, underwent subclavian perivascular brachial plexus dupraclavicular, with the aid of a peripheral neurostimulator, for orthopedic surgeries of the upper limbs. One can choose several approaches whose common denominator is the larger volume of local anesthetics required, comparing with neuroaxis blocks, and making the choice of the local anesthetic crucial.

The present study demonstrated that the anesthetic qualities of pure levorotatory bupivacaine in brachial plexus block are similar to that of the racemic mixture. Reg Anesth Pain Med, ; Showing of 26 references. The latency of the sensorial blockade in C 5C 6C 7and C 8 metameres did not show normal distribution; therefore, median and 25 th and 75 th percentiles were used in the respective statistical analyses.
