Paresthesias are
|
radiating electric shock-like sensations that can occur during regional anesthetic procedures.
|
|
|
When paresthesias occur,
|
the block needle should be slightly repositioned before injection of local anesthetic solution.
|
|
|
A motor response evoked with currents of
|
approximately 0.5 rnA indicates sufficient proximity of the block needle to the nerve for success of the block after the Injectlon of local anesthetic solution.
|
|
|
The brachial plexus arises from .
|
the anterior rami of CS through C8 and T1. These rami unite to form three trunks in the space between the anterior and middle scalene muscles and then pass over the first rib and under the clavicle to enter the axilla
|

|
INTERSCALENE BLOCK
|
An interscalene block of the brachial plexus is achieved by injecting 25 to 40 mL ofloeal anesthetic solution into the interscalene groove adjacent to the transverse process of C6 (the external jugular vein often overlies this area)
An interscalene block of the brachial plexus should be performed with the ann at the patient's side to relax the shoulder. |

AXILLARY BLOCK
|
An axillary brachial plexus block is achieved by injecting t · 30 to 40 mL oflocal anesthetic solution around the nerves that lie in close proximity to the axillary artery
