ABSTRACT:
A device and a method for determining a required length of an epidural catheter for a continuous epidural anesthesia, has an element formed as a ruler and having two opposite sides, a shorter scale provided on one side of the ruler and having a length substantially corresponding to a length of an epidural needle, and a longer scale provided on the other side of the ruler and being longer than the shorter scale by a length corresponding to a required length of an epidural catheter inside an epidural space, so that when an epidural needle is inserted in the epidural space and the ruler is placed against the skin parallel to the epidural needle, then when an epidural catheter is placed parallel to the ruler extending from a hub of the epidural needle along the longer scale, its length between the hub of the epidural needle and a beginning of the longer scale corresponds to a required length of the epidural catheter to be inserted into a patient.
