How does fracture cause fat embolism?
Soft tissue damage and burns can cause fat embolisms, although far less frequently than fracture. The most popular theory about the etiology of fat embolism is that fat globules (emboli) are released by the disruption of fat cells in fractured bone and enter through ruptures in marrow vascular beds.
What do you do for a fat embolism?
There is no specific treatment for a fat embolism. That is why prevention can reduce the length of hospital stays and lower the risk of complications and death. Some preventative strategies include : blood oxygen monitoring to help detect a fat embolism early, before symptoms become severe.

Why does a fat embolism cause a petechial rash?
Occulsion of dermal capillaries by the fat emboli resulted in petechial rash. Petechiae rash occurs in 50 to 60% of the cases. Neurologic signs such as confusion, stupor, and coma maybe present. These are usually temporary and does not happen on one side of the body.
Can you see fat embolism on CT scan?
CT is often normal or demonstrates edema. MRI may also show foci of vasogenic edema in a random (i.e. embolic) distribution but classically a “starfield” pattern may be seen on DWI.
What is a fat embolism from amputation?
Fat embolism syndrome occurs when fat enters the blood stream (fat embolism) and results in symptoms. Symptoms generally begin within a day. This may include a petechial rash, decreased level of consciousness, and shortness of breath. Other symptoms may include fever and decreased urine output.
Can you get sepsis from a broken bone?
Can you get an infection from a fracture? The simple answer is yes. However, most broken bones do not lead to infections. In rare cases, fractures, particularly open fractures, can lead to infection and a long treatment and recovery process.
