Trigeminal nerve palsy and Horner's syndrome following epidural analgesia for labor: a subdural block?

Horner's syndrome is a rare complication of epidural analgesia for labor. Much more uncommon is trigeminal nerve palsy. Both complications may be attributed to a subdural localization of the catheter, as we demonstrated clinically by a repeat injection and patchy sympathetic block and with the typical image on epidurography.
