Low i.v. regional analgesia with bupivacaine for hand surgery

A forearm tourniquet for i.v. regional analgesia of the hand, using doses of bupivacaine smaller than in the conventional (upper arm) method, produced successful analgesia in 98 of 102 patients. In 63 patients bupivacaine 50 mg or less was adequate, while in 33 the dosage was between 60 and 75 mg. No toxic effect was noted. This technique permits surgery of the hand, wrist and distal forearm.
