Bilateral variant locations of the musculocutaneous nerve during ultrasound-guided bilateral axillary brachial plexus block: A case report

ABSTRACT

Ultrasound-guided peripheral nerve block has several advantages over traditional techniques for nerve localization. One is a reduction of local anesthetic dose required for successful nerve block, which might allow bilateral brachial plexus block to be performed without risk of local anesthetic toxicity. Another advantage is the ability to detect anatomical variations in nerve and vascular anatomy. We report the case of a patient with unilateral anatomical variations of the musculocutaneous nerve found in ultrasound-guided bilateral axillary brachial plexus block.
