Abstract

|
Fat embolization is a common occurrence after trauma or during orthopedic procedures involving intramedullary manipulation. Although uncommon, fat embolism syndrome (FES) with respiratory failure, neurologic dysfunction, and petechial rash can be fatal to patients. Two theories are proposed for the manifestation of FES: in the mechanical theory, FES occurs when fat tissue in the bone marrow enters the bloodstream and mechanically blocks it; the biochemical theory proposes that FES occurs due to an inflammatory reaction caused by free fatty acids. There are currently no clear diagnostic criteria for FES, and symptoms and signs are typically nonspecific. For the treatment of FES, conservative and supportive management is performed for the specific symptoms, and close monitoring of the respiratory and neurologic systems is required in high-risk groups. Early fracture fixation of long bones helps prevent and reduce the severity of fat embolism.
