Case report: high sympathetic block with ptosis after lumbar epidural analgesia in an obstetric patient.

Following lumbar epidural analgesia, a 26 year old primigravida developed right ptosis and other signs of paralysis of the right sympathetic supply to the head and neck. The case is discussed and compared with cases of Horner's syndrome which have followed epidural analgesia. It was probably due to differential sympathetic blockade.
