[Diagnosis of accidental subdural block].
Accidental subdural block occurred in a 47-year-old man who underwent gastrectomy under nitrous oxide-sevoflurane anesthesia combined with continuous epidural block. The development of subdural block was suspected from unexpectedly severe hypotension with small doses of mepivacaine during operation and was confirmed by a characteristic X-ray photograph after operation. The subdural block should be suspected from abnormal changes in vital signs and by careful observation of X-ray photographs, because it is not always easy to determine the presence of contrast media either in the subdural space or in the epidural space.
