Paraplegia after delayed detection of inadvertent spinal cord injury during thoracic epidural catheterization in an anesthetized elderly patient.
We report a case of permanent paraplegia in an 81-yr-old patient who had thoracic epidural catheterization performed under general anesthesia for abdominal surgery. The epidural needle was introduced at the T9-10 interspace, and 3 passes were made to locate the epidural space with the loss-of-resistance-to-air technique. During the postoperative epidural pump infusion, the patient was unaware of the progressive motor and sensory impairment. Sensory loss below T11 and paraplegia with no movement of either lower extremity were identified 8 h after surgery. Magnetic resonance imaging demonstrated an intramedullary split-like lesion extending from T4 to T12 and an intramedullary air bubble at T9. Spinal cord injury caused by an intracord catheterization with subsequent local anesthetic injection was diagnosed. Little improvement was noted after large-dose IV methylprednisolone for initial treatment and subsequent rehabilitation for 6 mo. The possible causes of the delayed detection of the neurologic deficits and the timing of performing epidural anesthesia are discussed.
