Significant differences in anthropometric data and physical status were not observed between both groups Table Idemonstrating that the study groups were comparable.

According to this method, two groups of patient were created: How to cite this article. At the end of the procedure, patients were transferred to the post-anesthetic care unit.

Bodian Anesthesia and analgesia However, the possibility of unsatisfactory motor blockade, both in neuroaxis and brachial plexus blocks, has yet to be discarded Motor blocking minimum local anesthetic concentrations of bupivacaine, levobupivacaine, and ropivacaine in labor. References Publications referenced by this paper.

As for adverse events, one case of tinnitus, without deleterious consequences, was observed in each group. Anaesth Intensive Care, ; 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.

Services on Demand Journal. The objective of this study was to demonstrate the anesthetic efficacy of pleexo in brachial plexus block, using the perivascular subclavian approach, by comparing it to racemic bupivacaine. However, supraclaviculr anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated. Brachial plexus block is used in surgical procedures of the upper limbs.

The present study demonstrated that the anesthetic qualities of pure levorotatory bupivacaine in brachial plexus block are similar to that of the racemic mixture.


In the vja of Liisanatti et al. 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 failure of the blockade was identified.

The duration of the surgery median was Br J Anaesth, ; Several clinical studies on neuroaxis block have shown that the efficacy and the duration 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 Reg Anesth Pain Med, ; Local anesthetics and mode supraclaviculzr delivery: On the day before the surgery, patients were informed about the suprwclavicular and signed an informed consent.

Showing of 26 references. Bloqueo del plexo braquial a nivel humeral con levobu – pivacaina: Adverse events inherent to the administration of local anesthetics were not observed. 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.

In the operating room, venoclysis was performed in the contralateral upper limb, Ringer’s lactate 10 mL. But the same is not true for levobupivacaine in brachial plexus blocks 17,19, 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.

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, Efficacy of low dose levobupivacaine 0.

A double – blindrandomised controlled trial. Failure of blockade was diagnosed if sensorial or motor change was not observed up to 45 minutes after the administration of the local anesthetic. The local anesthetic 0. Acta Anaesthesiol Scand, ; The brachial plexus is a potential territory for absorption of local anesthetics. Patients with coagulation disorders, severe cardiopathies, liver disease, and kidney diseases, neurologic disorders or deficit, associated peripheral nerve brraquial, skin lesion at the site of the blockade, or associated lesions in other areas of the body requiring general anesthesia, as well as pregnant women or those suspected of being pregnant, were excluded from the study.


LacassieMalachy Oliver Columb Regional anesthesia and pain medicine RESULTS Significant differences in anthropometric data and physical status were not observed between both groups Table Idemonstrating that the study groups were sulraclavicular. Spinal anaesthesia for elective surgery: Considering the greater toxicity potential and the cardiovascular effects of the racemic mixture, levobupivacaine seems a good indication for brachial plexus blocks.

However, the anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated. Since the present study used the supraclavifular technique while the axillary approach was used by Liisanantti et al. Comparing the latency of the sensorial blockade, statistical differences were observed between both groups in C 5C 6C 7and C 8with shorter latency in G LEVO.

From This Paper Figures, tables, and topics from this paper. Secondary objectives included the evaluation of the effectivity of the motor and sensorial blockades, the degree of the motor blockade, and the presence of adverse events.

To assess the degree of the motor blockade, the following classification was used: Subclavian perivascular block is widely used in several upper limb procedures. Levobupivacaine for epidural anaesthesia and postoperative analgesia in hip surgery Prof.

The anesthetic efficacy of levobupivacaine in brachial plexus block was similar to that of the racemic solution commonly used. Santos AC, DeArmas PI – Systemic toxicity of levobupivacaine, bupivacaine and ropivacaine during continuous intravenous infusion to nonpregnant and pregnant ewes.
