However, the anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated. Bodian Anesthesia and analgesia However, the possibility of unsatisfactory motor blockade, both in neuroaxis and brachial plexus blocks, has yet to be discarded Acta Anaesthesiol Belg, ; Reg Anesth Pain Med, ; Rev Esp Anestesiol Reanim, ; Local anesthetics and mode of delivery: Surpaclavicular on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine.

Adverse vvia inherent to the administration of local anesthetics were not observed.

Acta Anaesthesiol Scand, ; Bloqueo del plexo braquial a nivel humeral brawuial levobu – pivacaina: Sensorial blockade was evaluated by pinprick stimulation of C 5C 6C 7and C 8 metameres 1, 2, 5, 10, 15, 20, 25, and 30 minutes after the administration of the local anesthetic and every five minutes until the effectivity or braqial of the blockade was identified. After establishment of the blockade, sedation was supplemented with sequential intravenous boluses of 1 mg of midazolam, and patients remained in horizontal dorsal decubitus with oxygen via nasal catheter.

In the present study, shorter latency baquial the sensorial blockade was observed in the levobupivacaine group in all metameres evaluated, but both groups had similar incidence of failures. To assess the degree of the motor blockade, the following classification was used: How to cite this article. Patients were assigned according to an increasing numeric sequence that classified the local anesthetic provided by the laboratory.


Kean J, Wigderowitz CA, Coventry DM – Continuous interscalene infusion and single injection using levobupivacaine for analgesia after surgery of the shoulder. A double – blindrandomised controlled trial. The primary outcome of the study included the latency and prevalence of motor blockade failures.

The anesthetic efficacy of levobupivacaine in brachial plexus block was similar to that of the racemic solution commonly used. References Publications referenced by this paper.

The duration of the plfxo median was A considerable number of studies on the bloqkeo of levobupivacaine in subarachnoid blocks and, especially, in epidural blocks can be found in the literature. Spinal anaesthesia for elective surgery: Anthropometric data underwent descriptive analysis and, according to the parameter, the following tests were used: Pharmacokinetics and pharmacodynamics of bupivacaine enantiomers in the isolated perfused rabbit heart.

Brachial plexus block has long been considered a safe method when proper technique is observed, which includes monitoring and patient selection.

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.

Fifty adult patients of both genders, ASA I and II, underwent subclavian perivascular brachial plexus block, with the aid of a peripheral neurostimulator, for supraclavicuoar surgeries of the upper limbs. The primary objectives of the present study included comparing the latency and prevalence of failure of the motor blockade of racemic bupivacaine and levobupivacaine in subclavian perivascular brachial plexus block.

Continuous interscale – ne infusion and single injection using levobupivacaine for analgesia after surgery of the shoulder. Topics Discussed in This Paper. This lack of consensus was the basis for this study, i. In case of failure, the patient underwent general anesthesia and the procedure was carried out.

Br J Anesth, ; RESULTS Significant differences in anthropometric data and physical status were not observed between both groups Table Idemonstrating that the study groups were comparable. The present study demonstrated that the anesthetic qualities of pure levorotatory bupivacaine in brachial plexus block are similar to that of the racemic mixture.

The motor blockade in the hand did not show statistically significant differences. 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, Cox et al. Comparing the latency of the sensorial blockade, statistical differences were observed between both groups in C 5Supraclavicjlar 6C 7and C 8with shorter latency in G LEVO. At the end of the procedure, patients were transferred to the post-anesthetic care unit.
