Abstract
Background: Thoracic epidural anesthesia is frequently used to maintain intraoperative and postoperative
analgesia. Frequently, 3 ml of local anesthetic is used as a test dose, or for intermittent epidural injection.
We assessed the extent of the spread of 3 ml of contrast medium in the thoracic epidural space and attempted
to identify any correlating factors affecting the epidurography.
Methods: A total of 70 patients were enrolled in the study, and thoracic epidural catheterizations were
performed under fluoroscopic guidance. Using 3 ml of contrast medium, epidurography was evaluated to
confirm the number of spinal segments covered by the contrast medium. Correlation analysis was performed
between patient characteristics (sex, age, body mass index, weight, height, and location of catheter tip) and
the extent of the contrast spread.
Results: The mean number of vertebral segments evaluated by contrast medium was 7.9 ± 2.2 using 3 ml
of contrast medium. The contrast spread in the cranial direction showed more extensive distribution than that
in the caudal direction, with statistical significance (P < 0.01). Patient height demonstrated a negative
correlation with the extent of distribution of contrast medium (r = −0.311, P < 0.05).
Conclusions: Thoracic epidurography using 3 ml of contrast medium results in coverage of a mean of 7.9
± 2.2 spinal segments, with more extensive cranial spread, and patient height showed a weak negative
correlation with the distribution of contrast medium.
