Abstract

Dural puncture in a well recognised complications of lumbar epidural anesthesia, as is extensive block after extradural injection of local anesthetic solutions in patients in whom the dura has been punctured. A healthy 43-year-old woman entered for trans-abdominal hysterectomy under lumbar epidural anesthesia. After an accidental dural puncture was noticed then the epidural puncture was reattempted at the same site and a catheter was inserted succesfully. An extensive segmental anesthesia along with hypotension and pupil dilatation developed about 45 minutes after the first injection of lidocain. Such extensive segmental anesthesia may be the result of injection into the subdural space. However, it was not confirmed in this case radiologically.
