Key result
Continuous brachial plexus block historically reduces vasospasm and relieves pain after upper extremity vascular accidents.
Continuous brachial plexus block has been historically suggested for managing vasospasm and pain after upper extremity vascular accidents.
Early short-duration reports caution against routine adoption; leaves open prospective trials of extended continuous blocks.
CONTINUOUS brachial plexus block as a means of decreasing vasospasm, relieving pain, and promoting collateral circulation following upper extremity vascular accidents was suggested by Ansbro in 1946.1 He originally described the technic using the supraclavicular approach. The longest duration of brachial block reported was less than 5 hours, and the procedure was used primarily for surgical anesthesia.
