The anesthetic efficacy of levobupivacaine in brachial plexus block was vla to that of the racemic solution commonly used. Bodian Anesthesia and analgesia Only two studies compared racemic bupivacaine and levobupivacaine 17,21 while the other studies in the literature compared levobupivacaine and uspraclavicular 19,20 or evaluated different volumes, doses, concentrations, and routes of administration of levobupivacaine 18, According to this method, two groups of patient were created: Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine.

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 The relative potencies for motor block after intrathecal ropivacaine, levobupivacaine, and bupivacaine.

Pharmacokinetics and pharmacodynamics of bupivacaine enantiomers in the isolated perfused rabbit heart. 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.

Considering the greater toxicity potential and the cardiovascular effects of the racemic mixture, levobupivacaine seems a good indication for brachial plexus blocks. 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. J Bone Joint Surg Br, ; The motor blockade in the hand did not show statistically significant differences.


However, the anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated.

Patients with coagulation disorders, severe cardiopathies, liver disease, and kidney diseases, neurologic disorders or deficit, associated peripheral nerve lesions, 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. Patients were assigned according to an increasing numeric sequence that classified the local anesthetic provided by the braqkial.

In the present study, statistically significant differences in motor blockade latency, degree of the blockade, and failure rates were not observed between both groups, corroborating the results of Cox et al. After bloqudo 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.

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. 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.


LacassieMalachy Oliver Columb Regional anesthesia and pain medicine Eur J Anaesthesiol, ; Spinal anaesthesia for elective surgery: 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 objective of this study was to demonstrate the anesthetic efficacy dde levobupivacaine in brachial plexus block, using the perivascular subclavian approach, by comparing it to racemic bupivacaine.

To assess the degree of the motor blockade, the following classification was used: However, Cox et al.

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

Motor blocking minimum local anesthetic concentrations of bupivacaine, levobupivacaine, and ropivacaine in labor. Sensorial blockade was evaluated by pinprick stimulation from C 5 to C 8 metameres; and the motor blockade was assessed 1, 2, 5, 10, 15, 20, 25, and 30 minutes after blqoueo administration of the local anesthetic or until blockade of fingers, hand, forearm, and arm movements was observed.
