Question

Because it is important not to penetrate the nerve sheath or damage nearby blood vessels when performing this technique,a needle attached to a nerve stimulator may be inserted first.This allows the anesthesia provider to locate the nerves of the brachial plexus precisely.Approximately 30 to 40 mL of local anesthetic is injected around the nerves that are adjacent to the axillary artery,which makes the entire arm both numb and immobile.This technique may be used for the manipulation and casting of fractures in patients who are at high risk for complications of general anesthesia; thus it is a preferred technique for use in alcohol-intoxicated patients whose central nervous system is already depressed.The arm is exsanguinated before administering an IVRA (Bier block).
