Horner's syndrome as a complication of lumbar epidural anesthesia is a
relatively benign and transient condition that usually does not warra
nt further extensive investigation. Its occurrence is unpredictable, a
lthough more frequently associated with epidural anesthesia performed
for obstetric conditions. It may indicate high sympathetic blockade, a
nd those patients should be monitored closely for autonomic complicati
ons. We report two new cases of iatrogenic Horner's syndrome from lumb
ar epidural anesthesia.
