Myelopathy with syringomyelia following thoracic epidural anaesthesia.
Under general anaesthesia and muscle relaxation, a thoracic epidural catheter was inserted at the T8-T9 level in a 7-year-old boy scheduled to have a Nissen fundoplication to provide postoperative analgesia. After 4 ml of lignocaine 1.5% was injected through the catheter, hypotension resulted. Fifty-five minutes later 5 ml of bupivacaine 0.25% produced the same effect. In the recovery room a similar injection resulted in lower blood pressure and temporary apnoea. Sensory and motor deficits were noted the next day and four days later magnetic resonance imaging demonstrated spinal cord syringomyelia extending from T5 to T10. Four years later, dysaesthesia from T6 to T10 weakness of the left lower extremity and bladder and bowel dysfunction persist. The risks of inserting thoracic epidural catheters in patients under general anaesthesia and muscle relaxation are discussed, emphasising the possibility of spinal cord injury with disastrous consequences.
