통증 치료시 발생된 하지 마비 -증례 보고-

Abstract

Recently, continuous epidural catheter insertion is usually employed in operation and chron- ic pain control Delayed migration of an extradural catheter into subdural space or subarach- noid space is a rare but life threatening complication of continuous epidural catheter insertion, especially with out patients. The symptoms may include lower extremity weakness, hypoten- sion, drowsy and respiratory depression. We experienced two cases of lower extremity paralysis due to delayed migration into subdu- ral or subarachnoid spaces at our pain clinic. The tecnical procedures for continuous epidural catheterization went smoothly without any complications. However, clinical signs of lower ex- tremity paralysis and sensory loss developed gradually, about 2 hours and 30 minutes after the continuous epidural injection. Two cases were confirmed by subdurogram and myelogram.
