Case ReportsPhantom pain with probable reflex sympathetic dystrophy: efficacy of fentanyl infiltration of the stellate ganglion.
The stellate ganglion can alleviate phantom pain of the upper extremity, possibly because of the presence in it of enkephalin receptors, as has been suggested by experimental and clinical reports. A case is reported in which fentanyl, instead of local anesthetic, was used for stellate ganglion block. ⋯ Fentanyl infiltration of the stellate ganglion proved to be successful in the management of the pain and temperature sensation changes in the stump and phantom upper extremity.

Case ReportsSurvey of regional anesthetic practice among French residents at time of certification.
A survey of anesthesia practice was conducted among French residents in anesthesia at the end of their training. This study was performed mainly to evaluate the residents' experience in peripheral nerve blocks. ⋯ French residents in anesthesiology at time of certification are better trained for peripheral nerve blocks of the upper extremity than for those of the lower extremity. Axillary plexus and femoral nerve block are the most widely used blocks, probably reflecting the techniques the most mastered among teachers. Finally, the extensive use of a peripheral nerve stimulator by residents is probably the result of the widespread use of this device by teachers in France.

Effect of subarachnoid gabapentin on tactile-evoked allodynia in a surgically induced neuropathic pain model in the rat.
Spinal gamma-aminobutyric acid (GABA) receptors have been shown to modulate post-nerve injury-induced allodynia. This study sought to examine the antiallodynic effects of a GABA analog gabapentin [1-(aminomethyl)cyclohexaneacetic acid], given by subarachnoid injection in a rat neuropathic pain model. ⋯ Gabapentin shows antiallodynic effect, but its mechanism is not known. The failure to reverse this effect by GABA A or B antagonists at doses that reverse the effects of the respective agonists suggests that gabapentin is involved in the modulation of spinal systems by mechanisms that do not involve either a GABA A or a GABA B site.
