title: Uneven epidural analgesia-early diagnosis and correction: case reports.
abstract: Lateral displacement of the epidural catheter can cause uneven epidural analgesia. Early determination can be made by pulse-wave monitoring of sympathetic blockade of the lower extremities and by x-ray determination of the placement of the catheter tip. Withdrawal of the catheter tip to near the midline may correct uneven epidural analgesia.
