Continuous brachial plexus block at the axilla is very effective method for a timeconsumed operation on upper extremity and post-operative pain management. We studied the location of a catheter-tip and the spread of local anesthetic solution in brachial plexus sheath using a radiopaque epidural catheter and a different amount of contrast medium. In almost all cases, the catheter roled up and its tip could never be located above the level of clavicle. A satisfactory block, however, could be obtained when at least 40ml of local anesthetic solution was injected and the spindle shaped sheath was seen in roentgenogram.
