Tunneling Does Not Prevent Dislodgment of Epidural Catheters: A Randomized Trial.

Background: Epidural analgesia is preferred in postoperative pain control, but dislodgment is a major factor for failure. Tunneling is well known to control displacement of catheters. In this study, we evaluated if we can depend on tunneling in preventing dislodgment of epidural catheters.
