Bodian Brauial and analgesia 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.

Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine. In the present study, shorter latency of the sensorial blockade was observed in the levobupivacaine group in all metameres evaluated, but both groups had similar incidence of failures.

The time between the administration of the local anesthetic and the onset of the blockade for each of the movements mentioned was recorded. Feldman HS, Arthur GR, Covino BG – Comparative systemic toxicity of convulsant and supraconvulsant doses of intravenous ropivacaine, bupivacaine and lidocaine in the conscious dog.
One can choose several approaches whose common denominator is the larger volume of local anesthetics required, comparing wupraclavicular neuroaxis blocks, and making the choice of the local anesthetic crucial. Brachial plexus block has long been considered a safe method when proper technique is observed, which includes monitoring and patient selection.
After establishment of the blockade, sedation was supplemented with supraclavicilar intravenous boluses of 1 mg of midazolam, and patients remained in horizontal dorsal decubitus with oxygen via nasal catheter. Br J Anaesth, ; The duration of the surgery median was Fifty adult patients of both genders, ASA I and II, underwent subclavian perivascular brachial plexus block, with the aid of a peripheral neurostimulator, for orthopedic surgeries of the upper limbs.
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 the administration of the local anesthetic or until blockade of p,exo, hand, forearm, and arm movements was observed. Spinal anaesthesia for elective surgery: At the end of the procedure, patients were transferred sulraclavicular the post-anesthetic care unit.
The latency and incidence of failures were not statistically different between both groups Table II. Local anesthetics and mode of delivery: A double-blind, randomised controlled trial.

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. The brachial plexus is a potential territory for absorption of local anesthetics. Considering the greater toxicity potential and the cardiovascular effects of the racemic mixture, levobupivacaine seems a good indication for brachial plexus blocks.
The brachial plexus is a potential territory for absorption of local anesthetics. Subclavian perivascular block is widely used in several upper limb procedures. 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. Rev Esp Anestesiol Reanim, ; A considerable number of studies on the use of levobupivacaine in subarachnoid blocks and, especially, in epidural blocks can be found in the literature.
According to this method, two groups of patient were created: Acta Anaesthesiol Belg, ; The motor blockade in the hand did not show statistically significant differences. Supraclavicular brachial plexus block:
