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.

The authors report their experience about 50 cases of supra clavicular plexus block realised by Kulenkampff method. The anesthesia obtained has been complete in 84% of cases and in the 16% remaining general anesthesia was necessary to permit surgery. ⋯ Actually the adoption of perivascular techniques of brachial plexus anesthesia (interscalenic, supraclavicular, axillary) have greatly improved the performance of this variety of upper limb locoregional anesthesia, thus reducing the percentage of failure and eliminating or reducing the risk of pneumothorax. Locoregional anesthesia of the upper limb should constitute a daily method in the surgery of upper limb and not a technic subordinated to the contra-indications of general anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Intrathoracic intercostal nerve block with phenol in open chest surgery. A randomized study with statistical evaluation of respiratory parameters.
Seventy-three patients who underwent thoracic surgery were randomly selected for intraoperative intercostal nerve block using phenol (32 block and 41 control subjects). The patients were divided into three groups: pneumonectomies, lobectomies and explorative thoracotomies and evaluated by pain level, respiratory function parameters (VT, IRV, ERV, VC) and blood-gas analysis, both six and 24 hrs after surgery. The patients who had intraoperative nerve block using phenol enjoyed a more comfortable postoperative period. In particular, respiratory parameters were statistically better.
