Set for continuous epidural anesthesia

A set for a continuous epidural anesthesia, comprising

• an epidural catheter for performing epidural anesthesia:
• and
• a device for determining a required length of said epidural catheter for administering epidural anesthesia and including an epidural needle insertable prior to administration of anesthesia into an epidural space and an element for determining the required length of said epidural catheter, said element being formed as a ruler and having two opposite sides, a shorter scale provided on one of said sides and having a length substantially corresponding to a length of said epidural needle, and a longer scale provided on the other of said sides and being longer than said shorter scale by a length corresponding to a required length of said epidural catheter inside said epidural space, so that when said epidural needle is inserted in the epidural space and said ruler is placed against a skin parallel to said epidural needle, then when said epidural catheter is placed parallel to said ruler extending from a hub of said epidural needle along said longer scale, its length between the hub of said epidural needle and a beginning of said longer scale corresponds to a required length of said epidural catheter to be inserted into a patient said shorter scale having a length of substantially 10 cm, while said longer scale has a length of substantially 13 cm.
