abstract: Brachial plexus blocks for upper extremity surgery: what are the preferred techniques? Brachial plexus anaesthesia for all types of upper extremity surgical procedures cannot be adequately achieved with a single technique. At least, two approaches are required: above the clavicle, Winnie's interscalene brachial plexus block, using a neurostimulator, has become the standard technique for shoulder surgery. Below the clavicle, midhumerus approach is the most successful approach for elbow, fore arm and hand surgery, especially for outpatient surgery. The best approach for catheter insertion along brachial plexus nerves/trunks remain controversial. The supraclavicular approach using surface landmarks might be the best approach due to its efficacy in achieving complete anaesthesia of the upper extremity and the rarity of secondary displacement of the catheter. Whatever the selected approach(es) to brachial plexus nerves, nerve location it best achieved by neurostimulation and often multiple neurostimulation. Insulated needles are being increasingly used due to accuracy but, currently, there is no general agreement concerning the type of needle bevel to be preferred in regard to both safety and accuracy.
