[Electrical nerve localization and catheter technic. A safe method for brachial plexus anesthesia].
A technique for sub-axillary blockade of the brachial plexus by means of a special catheter set is presented. A plastic self-retaining cannula is placed within the vasomotor nerve sheath, using the advantages of electric nerve stimulation. In our opinion the decisive advantages of this procedure lie in the fact that the user is not dependent on the cooperation of the patient and anatomical orientation takes place on the basis of clear and objective criteria through the muscle contractions induced in this way. ⋯ This method makes subsequent injections into the vasomotor nerve sheath through repeated puncture unnecessary. The catheter technique makes it possible to operate on the upper extremity using regional anaesthesia, whose effects can be prolonged beyond those of long-acting anaesthetics. The possibility of incomplete blockade resulting from individual variations in the amounts of local anaesthetics needed, is excluded and the anaesthetist can, if necessary, carry out pre- and post-operative pain therapy.

Randomized Controlled Trial Clinical Trial
Penile block for pain relief after circumcision in children. A randomized, prospective trial.
The value of adjunctive penile block for analgesia, after circumcision in children using 0.5 percent bupivacaine has been evaluated in this randomized, prospective trial. Significantly more children without nerve block were found to require analgesics, administered by injection orally, in the first 12 hour period when compared with children given the nerve block. Penile block is a procedure that is safe, simple to achieve, free from complications, and covers the postoperative period when analgesia is much needed.

India ink was injected through extradural catheters placed in the posterior intercostal space in 12 cadavers undergoing autopsy and the subsequent spread of the India ink was assessed under direct vision. The ink spread subpleurally to reach a number of intercostal spaces and medially to reach the paravertebral space. It is concluded that analgesia extending over a number of dermatomes is achieved by subpleural tracking of local anaesthetic to reach intercostal nerves above and below the one injected.

A jet injector was used to perform intercostal nerve block as a method of intra-operative and postoperative pain relief at cholecystectomy, using a concentrated solution of local analgesic. This method was shown to be as successful as the conventional needle technique. The risk of pneumothorax, and the problems of the local analgesic solution used are discussed.
