Ultrasonographic study of the spread of local anaesthetic during axillary brachial plexus block

Abstract

Ultrasonography has been used to demonstrate the anatomy of the axilla, to confirm the placement of a cannula and to visualize the spread of a local anaesthetic solution in the axillary sheath of 10 patients (aged 17-70 yr) for surgery of the forearm and hand. The block was successful in all subjects.
