Eighty-four cases of inguinal hernioplasty by Bassini's modified technique were performed using 1% lidocaine in regional infiltration block. The report analyzes the use of local anesthesia in the treatment of inguinal hernias. All patients had small reducible and non-recurrent inguinal hernia. ⋯ The rate of complication was low, but pain was a common complaint. In general, there was a good acceptance of this kind of anesthesia. The authors concluded that local anesthesia is a valuable method for the treatment of inguinal hernia.

Technique of pudendal nerve localization for block or stimulation.
A diagnostic technique is described for study of the pudendal nerve via a dorsal rather than perineal approach. The method offers unique advantages for the urodynamic study of sphincteric function. The patient is placed in the prone position with slight flexion of the hips. ⋯ Local anesthesia and electrical stimulation then are used to position a needle tip adjacent to the pudendal nerve. This approach allows for specific localization of the nerve for accurate temporary or permanent nerve block. It also permits continuous urodynamic monitoring of pelvic floor behavior with stimulation of the pudendal nerve to assess functional integrity of the nerve and the pelvic floor striated muscles.

The supraclavicular brachial plexus block originated by Kulenkampff is useful but accompanies the danger of injury to the lung, i.e. pneumothorax, because the needle is directed caudad. Reviewing the anatomy of the brachial plexus in cadavers, we have found that the parascalene brachial plexus block originated by Vongvises is safer than Kulenkampff's method. We modified this block as follows: (1) An assistant pulls lightly the affected upper extremity caudad. (2) A 23-gauge 35 mm needle is inserted at right angles to the clavicle and directed cephalad at an angle of 0-30 degrees. ⋯ Our success rate was 92%. The only complication we encountered was Horner's syndrome which occurred in 20% of our cases. None of our patients showed clinical symptoms of pneumothorax, hematoma, epidural as well as subarachnoideal block, recurrent nerve paralysis or phrenic nerve paralysis.

Eight-five carotid endarterectomies were performed in 77 patients, under regional anaesthesia using 2 different techniques: cervical epidural anaesthesia (35 cases) and cervical plexus block (50 cases). The patients' mean age was 71 years; 80 per cent had arterial hypertension and 41 per cent coronary disease. Transoperative cerebral ischaemia was detected by a 5-minute carotid clamping test, the occurrence of a neurological event indicating that shunting was required. ⋯ The analgesia obtained was equally good with both anaesthetic techniques, but cervical plexus block anaesthesia is easier to perform, had less haemodynamic repercussions and therefore tends to be preferred to cervical epidural anaesthesia. The lack of mortality, low morbidity and absence of systemic complications in this series despite the high number of patients at risk are in favour of this type of anaesthesia, notably for such patients. Moreover, because vigilance is preserved attention can be paid to the quality rather than the rapidity of endarterectomy, which is the best way of preventing embolism.
