AbstractThe breakage of an epidural catheter within a patient is an uncommon but troublesome complication of continuous epidural block, and its cause is rarely discovered. Several possible mechanisms for catheter breakage have been proposed, but few can be reproduced experimentally. Review of two recent medicolegal cases concerning catheters that were severed at the time of insertion led to laboratory studies in an attempt to find an explanation. The results of this work demonstrated that it was possible to break or severely damage an epidural catheter by heavy contact between the tip of the epidural needle and a bony surface, if a length of the catheter was protruding from the tip.
