[Lumbosacral plexus block by the paravertebral route]

The authors present a detailed account of a technique of peripheric anesthesia of the lower limb, obtained with a single transcutaneous injection, blocking lumbar and sacral plexus, by a paravertebral way. Encouraging results have been reached in the treatment of both old (no cerebral or cardiorespiratory depressant effects) and young patients, which are frequently under day-hospital treatment. According to their experience, this technique is simple, easy to perform and less dangerous if compared to anesthesia obtained by spinal approach.
