1. A method of determining a required length of an epidural catheter for a continuous epidural anesthesia, comprising the steps of providing an element formed as a ruler having a shorter scale on its one side with a length corresponding to a length of an epidural needle and a longer scale on its other side which is longer than the shorter scale by a length corresponding to the required length of the epidural catheter inside an epidural space;

  • inserting an epidural needle into an epidural space;

    placing said ruler against a skin parallel to said epidural needle; and

    placing an epidural catheter from a hub of said epidural needle along said longer scale, so that a distance from the hub of the epidural needle to a beginning of said longer scale corresponds to a required length of the epidural catheter to be inserted into a patient.
