An adductor contraction secondary to obturator nerve stimulation can occur during transurethral resection of a lateral bladder lesion and then can induce bladder perforation or hamper complete resection. Many technique have been advocated but they are ineffective or unreliable. Obturator nerve blockade in the obturator canal by local anesthesia with control by nerve stimulator can prevent these complications. The technique described, has been used in 12 patients it is reliable, fast and easy to perform.

Comparative Study
Ilioinguinal nerve block in children. A comparison with caudal block for intra and postoperative analgesia.
Fifty-two boys undergoing herniotomy, orchidopexy or ligation of patent processus vaginalis under general anaesthesia had supplementary analgesia; 26 had a caudal epidural block and 26 an ilioinguinal block. Analgesia was assessed both during and after surgery. Ilioinguinal block provides a useful alternative to caudal block.

The distribution of paraesthesiae evoked by a low power nerve stimulator during performance of supraclavicular brachial plexus block was studied in 120 patients. Evoked paraesthesiae in the distribution of the median nerve was associated with a significant improvement in effectiveness of the block when compared with evoked paraesthesiae in the ulnar and radial distributions. A possible explanation for this finding is proposed.
