[Infraclavicular vertical brachial plexus blockade. A new method for anesthesia of the upper extremity. An anatomical and clinical study].

Patchy analgesia and incomplete motor blockade sometimes occur during surgery of the upper limb under axillary brachial plexus blockade. To avoid these problems, we sought an alternative approach to the brachial plexus to guarantee reliable anaesthesia. Based on anatomic studies, we undertook a prospective clinical study with 175 patients.
