Local and regional anesthesia; with chapters on spinal, epidural, paravertebral, and parasacral analgesia, and other applications of local and regional anesthesia to the surgery of the eye, ear, nose and throat, and to dental practice . EMITIES 247 entire radial side of the hand. Higher up in the forearm, at the junc-tion of the middle and lower third on the outer border, where theintermuscular septum divides the flexor from extensor muscles, theradial nerve is also fairly accessible, and may be successfully blockedat this point by passing the needle vertically inward beneath thesupinator longus. The following experiment by Dr. Braun illustratesthe results obtained: Experiment 7 (May 2, 1902, Dr. D.). Twelve oclock, an injection of i of 2 percent, cocain solution in the above-described way, the needle had exactly met the nerve-trunk, as indicated by the radiating paresthesia. No constriction. Immediately afterthe injection occurred a marked radiating paresthesia and sense of warmth in the , complete regional anesthesia of the nerve; anesthesia of the skin is indicated, asin Fig. 37, No. II. Motor paralysis of the radial. After forty minutes sensibility andmotility returned. M interosseus dors Midnarts. ulnaris A. radia/is fisdmlis\N. median us lofig. Fig. 35.—Cross-section through forearm three fingers-breadth above pisiform bone (From Braun.) The ulnar nerve is accessible, either for exposure by dissection andintraneural injection or for paraneural injection, above the wrist-joint, preferably three or four fingers breadth above to insure reach-ing the posterior branch, which may be given off this high up. Inthis position the nerve lies between the tendon of the flexor carpiulnaris and the ulnar, as shown in Fig. 35, and is best reached forparaneural injections by introducing the needle from the ulnar sidebetween the tendon and the bone in the direction indicated by thearrow. It is rather unsafe and inadvisable
