The site that triggered muscular response to a stimulus equal to or lower than 0. Acta Anaesthesiol Belg, ; References Publications referenced by this paper. 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.

In the operating room, venoclysis was performed in the contralateral upper limb, Ringer’s lactate 10 mL.

However, the possibility of unsatisfactory motor blockade, both in neuroaxis and brachial plexus blocks, has yet to be discarded Bodian Anesthesia and analgesia Levobupivacaine for epidural anaesthesia and postoperative analgesia in hip surgery Prof. Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form levobupivacaine.

Sensorial blockade was evaluated by pinprick stimulation from C 5 to C 8 metameres; and supralavicular 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 fingers, hand, forearm, and arm movements was observed.

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.

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


The relative potencies for motor block after intrathecal ropivacaine, levobupivacaine, and bupivacaine. The duration of the surgery median was The motor blockade in the hand did not show statistically significant differences.

Continuous interscale – ne infusion and single injection using levobupivacaine for analgesia after surgery of the shoulder. Skip to search form Skip to main content.

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. Brachial plexus block is used in surgical procedures of the upper limbs. Inclusion criteria were as follows: 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 latency and incidence of failures were not statistically different between both groups Table II.

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

Suprsclavicular brachial plexus is a potential territory for absorption of local anesthetics. Motor blocking minimum local anesthetic concentrations of bupivacaine, levobupivacaine, and ropivacaine in labor.

However, brachial plexus blockade can set a potential place for absorption of local anesthetics and the development of systemic toxicity The time between the administration of the local anesthetic and the onset of the blockade for each of the movements mentioned was recorded. According to this method, two groups of patient were created: 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.

J Bone Joint Surg Br, ; 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 supraclavicklar were used in the respective statistical analyses.
