The ideal dose of dexmedetomidine for brachial plexus block is a matter of debate. However, there were no statistically significant difference in mean duration of sensory and motor block between Group B 0. Together, these observations enhance our understanding of the anatomic dynamics involved in brachial plexus blockade, and the thesis presents a new model based on the rigid anatomy surrounding the plexus. The brachial plexus is a potential territory for absorption of local anesthetics. Please review our privacy policy. Open in a separate window.

Onset time of each of the drug was recorded both for the sensory and motor block. Initially, the aim was restricted to trying to lessen the risk of pneumothorax by using the mathematical principle of the tangent, with the anatomy of the area requiring a bend in the block needle, but the project evolved into the more comprehensive task of also trying to alter the risk of blocking the phrenic nerve, sympathetic chain, and recurrent laryngeal nerve. The clinical versatility of this technique and its ability to avoid the phrenic nerve are clear advantages. However, there were no statistically significant difference in mean duration of sensory and motor block between Group B 0. The anesthetic efficacy of levobupivacaine in brachial plexus block was similar to that of the racemic solution commonly used. Although safe, ropivacaine is found to be less potent than bupivacaine and has a slightly shorter duration of action along with some motor sparing qualities [ 8 ]. References [1] Hall RJ.

Multiple comparison test with Bonferroni correction showed there was statistically significant difference in mean duration of sensory and motor block between Group A 0. The brachial plexus is a potential territory for absorption of local anesthetics.

Duration of sensory and motor block was recorded along with peri-operative haemodynamic monitoring. Patients were placed in the supine position with the head turned slightly away from the side to be blocked and the arm placed alongside the body.

High concentrations of dexmedetomidine inhibit compound action potentials in frog sciatic nerves without alpha 2 adrenoceptor activation. Adverse events inherent to the administration theais local anesthetics were not observed. Patients were randomly divided into two groups: Although safe, ropivacaine is found to be less potent than bupivacaine and has a slightly shorter duration of action along with some motor sparing qualities [ 8 ].

We have hlock to study ropivacaine as a safer alternative to bupivacaine and also tried to find out the most effective concentration of Ropivacaine for the supraclavicular brachial plexus block.
