Randomized Controlled Trial Clinical Trial
Effect of transcutaneous electrical nerve stimulation on onset of axillary plexus block.
We examined the effect of high frequency transcutaneous electrical nerve stimulation on the onset of brachial plexus block. Three groups of patients scheduled for surgery of the hand had a local anaesthetic block performed with 40 ml mepivacaine 1.5% using the axillary approach. ⋯ There were no differences in the onset of block between the groups. Thus, the frequency-dependent action of local anaesthetics could not be demonstrated.

Alkalinisation of lignocaine to reduce the pain of digital nerve blockade.
To see if the alkalinisation of lignocaine caused a reduction in the pain of injection for digital nerve blockade. ⋯ Alkalinisation of lignocaine reduces the pain of injection for digital nerve blockade.

Case ReportsPeripheral nerve catheterization in the management of terminal cancer pain.
Peripheral nerve catheterization techniques were used in two patients with severe pain associated with the terminal stages of metastatic cancer. The first patient had severe upper limb pain and lymphedema secondary to breast carcinoma, and the second patient had an acutely ischemic leg secondary to pelvic obstruction from an ovarian tumor. The goal of treatment was to relieve the pain, which was resistant to opioid drugs, and to optimize the quality of life that remained, estimated to be only a few weeks. ⋯ Peripheral nerve catheterization proved beneficial in two patients who presented with difficult pain management problems and should be more widely considered for the relief of severe cancer-related pain in both the upper and lower limbs.

[Clinical experience in interscalene brachial plexus block combined with Ho's method of C3-4 block for shoulder and proximal upper extremity surgeries].
Brachial plexus block, first performed in 1889 by Halsted, has been widely used for surgery of shoulder and upper third of upper extremity. But the level of block is inadequate for surgery of the deeper tissue. If high volume of local anesthetic (40 ml) is used to block C3-4, complications like Horner's syndrome and phenic nerve palsy would be frequent. The landmark of C-3 and C-4 nerve root is difficult to identify. The purpose of this study was to design a new method to block easily the C-3 and C-4 nerve roots for surgery of shoulder deep tissue. ⋯ Interscalene brachial plexus block combined with Ho's method of C3-4 block is technically safe and economical for patients receiving shoulder and proximal third of upper extremity surgery. We must make selection of patients carefully and exclude those whose anatomical landmarks are difficulty identified. As such, good result is expected.
