[The external jugular vein course as surface landmark in subclavian perivascular block].
A study of 88 orthopaedic patients undergoing upper limb surgery, was carried out using the external jugular vein as surface landmark of the brachial plexus in subclavian perivascular technique. A significant statistical relationship was found between the insertion point of the needle, relatively to the external jugular vein course, and the block outcome. The best results were observed when the needle was inserted on the postero-lateral side of the vein or when the insertion point coincided with the vein course. Worse results were obtained by foreward insertion. So the external jugular vein could be used as surface landmark to improve the plexus localization in the subclavian perivascular technique of brachial plexus anaesthesia.
