[Continuous block of the brachial plexus with nerve stimulation. Intra and postoperative control in orthopedic surgery of the arm].
A perivascular axillary plexus block was performed to 87 patients scheduled for orthopedic surgery of hand or arm using an electric nerve stimulator. A catheter was inserted for the postoperative pain control. ⋯ Complications were: arterial puncture (3), difficulty in inserting catheter (3), injection out of the sheath (1), pain at the electric stimulation (3). No allergic reactions nor neurologic complications were founded during a year of posterior control.

Fifty-four patients developed severe intercostal neuralgia a few weeks after sternotomy. Immediate relief afforded by parasternal nerve blocks confirmed that the pain derived from scar-entrapped neuromas of the anterior rami of the first 4-6 intercostal nerves in the upper (and mainly left) interchondral spaces after insertion of the sternal wires. Permanent relief (i.e., over 6 months) followed repeated bupivacaine blocks in 57.4% of the patients, phenol blocks in another 22.2%, and alcohol blocks in a remaining 9%. Treatment was successful in 87% of the patients.

[Initial experiences with a novel nerve stimulator for use in axillary plexus anesthesia].
The advantages of an electrical nerve stimulator for detection of the axillary neurovascular sheath have been frequently described in the literature and are now well known. In most of these techniques, stimulation is achieved by a fixed electrical voltage and variable amplification. The new nerve stimulator presented here offers the possibility of measuring the current at the site of stimulation ("test" position). ⋯ Thus, disturbances in the circuit between nerve stimulator and patient, as shown in the two cases, can be detected. According to our experience, the intensity of stimulation for successful nerve blockade should be approximately 0.5 mA or lower. Consequently, universally applicable stimulating instruments with constant electrical tension should allow fine tuning of the current in 0.1-mA aliquots.
