Bloqueo continuo del plexo braquial vía supraclavicular – Gerardo Luis García García – Google Books

The present study demonstrated that the anesthetic qualities of pure levorotatory bupivacaine in brachial plexus block are similar to that of the racemic mixture. 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. Santos AC, DeArmas PI – Systemic toxicity of levobupivacaine, bupivacaine supraclavicylar ropivacaine during continuous intravenous infusion to nonpregnant and pregnant ewes.

Patients were randomly divided into two groups: But the same is not true for levobupivacaine in brachial plexus blocks 17,19, Subclavian perivascular block is widely used in several upper limb procedures.

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. However, the anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated. The use of levobupivacaine in brachial plexus block seems promising considering the lower toxicity and the need of large volumes.

This lack of consensus was the basis for this study, i. Brachial plexus block has long been considered a safe method when proper technique is observed, which includes monitoring and patient selection. Acta Anaesthesiol Belg, ; J Bone Joint Surg Br, ; Comparing the latency of the sensorial blockade, statistical differences were observed between both groups in C 5C 6C 7and C 8with shorter latency in Supraclavucular LEVO.

The relative potencies for motor block supraclaviculzr intrathecal ropivacaine, levobupivacaine, and bupivacaine. Spinal anaesthesia for elective surgery: A considerable number of studies on the use of levobupivacaine in subarachnoid blocks and, especially, in epidural blocks can be found in the literature. From This Paper Figures, tables, and topics from this paper. However, the anesthetic efficacy sensorial and motor blockades of levobupivacaine in neuroaxis blocks has been debated.

In the present study, shorter latency of the sensorial blockade pleso observed in the levobupivacaine group in all metameres evaluated, but both groups had similar incidence of failures. In the present study, statistically significant differences in motor supraclaviculr latency, degree of the blockade, and failure rates were not observed between both groups, corroborating the results of Cox et al.

Motor blocking minimum local anesthetic concentrations of bupivacaine, levobupivacaine, and ropivacaine in labor. Those cases were maintained in the study and analyzed as blockade failures.

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

In the operating room, venoclysis was performed in the contralateral upper limb, Ringer’s lactate 10 mL. Bloqueo del plexo braquial a nivel humeral con levobu – pivacaina: 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 Motor blockade was evaluated by flexion of the 5 th finger, thumb adduction, extension, abduction, and flexion of the wrist, pronation of the forearm, and rotation and abduction of the humerus.


Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine. ZahnSabera HossainCarol Supraclavjcular. Levobupivacaine for epidural anaesthesia and postoperative analgesia supdaclavicular hip surgery Prof. Bodian Anesthesia and analgesia However, the bbraquial of unsatisfactory motor blockade, both in neuroaxis and brachial plexus blocks, has yet to be discarded However, statistical differences in the incidence of failures in the four metameres analyzed were not observed Table IV.

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 uspraclavicular racemic bupivacaine.
