[New landmarks for the subclavian approach of the brachial plexus. (With 44 clinical cases) (author's transl)].

The authors first recall the well-known techniques described by Kuhlenkampf, Winnie and others. They emphasize the sometimes difficult location of the subclavian artery, the fear of pneumothorax, especially for students learning this anesthesia method. Authors propose the use of new landmarks for brachial plexus anesthesia. These are the external jugular vein, sterno-cleido-mastoid muscle, and clavicular insertion of trapezius muscle. 44 cases of anesthesia using this method follows the description of the landmarks. The authors emphasize their low failure rate.
