Instead of previous conventional method, we have evaluated 42 cases of anesthetic effect by means of continuous axillary bracheal plexus block performed in Nationl Medical Center from May, 1984 to Oct. 1985. Although this method has been no longer new in western countries since several years ago, our effort to increase the success rate, durations and postoperative controls of pain and spasm solely by the method, were tried. Mainly using a 23 gauge, 3cm radio opaque reflon coated intravenous cather(HAKKO SHOJI CO, LTD, Dwell cath. type 3) inserted it into the axillary sheath, pointing towards the needle which was inserted to the apex of axilla with right angle in advance, about 400 or 500mg each of lidocaine, 1.5% with or without epinephrine, 1:200,000 were injected. This technique used was safe and had a high successful rate. It is particularly useful in patients undergoing long operation and in patients in whom postoperative vasodilatation would be needed after microreplantation of the hands.
