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.

[Blockade of the obturator nerve in transurethral electroresection of urinary bladder tumors].
Stimulation of obturator nerve during transurethral electroresection causes violent adductor muscle contraction, and is a major cause of inadvertent bladder perforation. General anesthesia with muscle relaxants is often required when the bladder tumor is in the area where the obturator nerve passes in close proximity to the inferolateral bladder wall. ⋯ We herein describe the technique and results of local obturator nerve blockade. Use of neutracer and pole needle makes the obturator nerve block a completely reliable, safe and easy procedure.

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.
