USG for brachial plexus block

Abstract

Ultrasound guided nerve block is now becoming the standard practice in regional anesthesia
and has been shown to require less volume of local anesthetic and reduce the incidence of
complications. Brachial plexus block can be approached via interscalene, supraclavicular,
infraclavicular or axillary routes. Each of these approaches have their individual advantages and
risk. This articles describes the indications, relevant sonoanatomy and techniques to perform
the blocks and recent advances.
