Transient Horner's Syndrome in a Trauma Patient with Thoracic Epidural Analgesia: A Case Report

Abstract

Horner's syndrome, which classically presents as ipsilateral ptosis, meiosis, and facial anhydrosis, may present as a consequence of thoracic epidural analgesia. Pain that limits the patient's ability to maintain adequate pulmonary mechanics may optimally be treated with a thoracic epidural. The importance of recognition of a Horner's syndrome in such a patient is critical in preventing unnecessary anxiety for the patient and potentially embarking on an unnecessary diagnostic workup. The following is a case presentation of a patient who sustained multiple rib fractures in an automobile accident. The patient presented with a Horner's syndrome after a thoracic epidural infusion had begun. This article highlights the importance of early recognition of this benign, transient syndrome and discusses the pathways and potential mechanism of this process.
