Accidental subdural catheterization due to complication of epidural anesthesia--a case report.
Although accidental subdural injection is a well-recognized complication of epidural block, only a mere handful cases have been substantially proven by radiological evidence. Here we report a case of subdural catheterization during the attempt of epidural anesthesia for a gynecological procedure. Its clinical course and radiological findings are compared with those of the cases previously reported in literature. Whenever there is the occurrence of widespread of sensory block together with respiratory distress and hemodynamic unstability following epidural injection of local anesthetic, a subdural injection should be considered in spite of a negative confirmation. Repeated subdural injection of a local anesthetic at the same site may predispose patients to serious morbidity. Therefore, we recommend that when a subdural injection is evident or suspected, reinsertion of the catheter in the epidural space via another entry or contemplation of a switch to another anesthetic technique is mandatory.
