Randomized Controlled Trial Clinical TrialThe effects of arm position on central spread of local anesthetics and on quality of the block with axillary brachial plexus block.
Spread of local anesthetic solution in axillary brachial plexus block is thought to be influenced by the position of the arm and the use of compression maneuvers. We investigated how these two factors affected central local anesthetic spread and block quality. ⋯ The central spread of local anesthetics is facilitated by injection without abduction of the arm but not by the use of compression at the injection site. This, however, did not alter the quality of the block.

The management of trigeminal neuralgia in older patients who do not want neurolytic block and/or surgical treatment may be problematic. This paper describes three patients who had first and/or second division trigeminal neuralgia. The analgesic effects of infraorbital nerve block using 0.5% bupivacaine or 1% mepivacaine dissipated within a few days, however, the effects of nerve blocks using 4% tetracaine dissolved in 0.5% bupivacaine continued for more than 3 months. Hypesthesia was observed in two patients within a week following the block, but sensory level returned to normal within 2 weeks and there were no further complications in any patient.
