Key result
In 125 patients receiving thoracic epidural analgesia for major abdominal surgery, the failure rate was 24.8%, with CT epidurography identifying catheter dislodgment as the primary cause.

Does CT epidurography identify the causes of epidural analgesia failure in patients undergoing major abdominal surgery?
CT epidurography reveals that the major cause of epidural analgesia failure after major abdominal surgery is catheter dislodgment.
Motamed et al. (2006) conducted a cohort in Epidural analgesia after major abdominal surgery (n=125). Thoracic epidural analgesia was evaluated on Epidural analgesia failure (visual analog scale pain score at rest > 30 mm and/or interruption before 48 h). In 125 patients receiving thoracic epidural analgesia for major abdominal surgery, the failure rate was 24.8%, with CT epidurography identifying catheter dislodgment as the primary cause.
