An evaluation of axillary block in 803 clinical cases, during the period from January 1974 to June 1979, was made. Satisfactory results were obtained in 756 out of 803 blocks (94. 2%) with the axillary perivascular technique. The authors feetl that the axillary perivascular technique in which a relatively large volume(40~50ml) of anesthetic solution was administered into the perivasculsr space of the axilla was simple, convenient and had no serious complications compared to the supra-or subclavian perivascular technique and interscalene block for a diagnosis and treatment of upper extremities.
