A technique for blocking the brachial plexus using a electrostimulator and conventional, non-special plastic cannula with an obtulator consist of conductive metal is described. This cannula is cheaper and more conventional than special plastic-coated needle. Brachial plexus block is useful anesthesia for surgical treatment of fractures, dislocations, skin and muscle injuries of the forearm and hand. ⋯ Therefore the method using an electrostimulator and a special plastic-coated needle for the brachial plexus block was reported in 1962 by Greenblatt. Employing a conventional plastic cannula for intravenous use instead of a special plastic-coated needle reported by Greenblatt. We could attain nerve block completely reliably, safely and easily.

Randomized Controlled Trial Clinical Trial[Inguinal funicular block in vasectomy].
The analgesic efficacy of inguinal funicular block with 10 ml carbocaine 1% as a supplement to local infiltration analgesia of the vas deferens was investigated in patients undergoing vasectomy. Pain/discomfort during vasectomy and on the first and third day postoperatively were investigated using a questionnaire. ⋯ There was significantly less intraoperative pain on the side of the active inguinal funicular block (p < 0.0001), but no significant differences were found at the first and third postoperative day (p = 1.16-1.19). Inguinal funicular block can be recommended as a supplement to the usual use of local infiltration analgesia of the vas deferens.

The number of AIDS patients is steadily increasing. According to the literature these patients are often in severe pain. ⋯ The high incidence of complicated neuropathic pain syndromes in AIDS patients requires a sophisticated therapeutic approach. Closer cooperation between AIDS specialists and pain specialists, comparable to that already existing for other patient groups, is therefore desirable.

Case Reports
Transient paraplegia from intraoperative intercostal nerve block after transthoracic discectomy.
To present two patients with transient paraplegia from intercostal nerve blocks after transthoracic discectomy. ⋯ Because of the inherent risk of neurologic injury after thoracic discectomy, the authors discourage the use of intercostal nerve blocks for relieving postoperative pain after transthoracic discectomy.

Phentolamine sympathetic block in painful polyneuropathies. II. Further questioning of the concept of 'sympathetically maintained pain'.
To test for the presence of "sympathetically maintained pain" (SMP), we administered placebo-controlled phentolamine sympathetic blocks to 14 patients with painful polyneuropathies. Six received i.v. infusion of saline for 30 minutes, followed by phentolamine (35 mg). In eight patients, the saline phase was followed by double-blind infusion of phentolamine or phenylephrine (500 micrograms), a second saline phase, and then the other active drug. ⋯ Five patients reported significant diminution of pain (> 50%), all in response to placebo. Neither phentolamine nor phenylephrine provided relief, although all patients had signs of physiologic abnormalities reputed to be determinants or predictors of SMP. These results complement previous studies demonstrating the nonexistence of SMP among "reflex sympathetic dystrophy" patients and further question the concept of SMP.
