Objective To study on diagnosis and treatment of brain type fat embolism syndrome complicated with fracture. Method The diagnosis and treatment of 7 cases of brain type fat embolism syndrome complicated with fracture were reviewed. All of 7 cases did not have any brain injury, 3 cases were complicated with femural fracture, 3 cases with fractures of tibia and fibula, and 1 cases with limbs multi fracture. They presented somnolence or coma complicated with rise in temperature (37.7℃～39℃) ,increase in breath and heart rate,anemia,small bleeding spots at chest. It was discussed how to distinguish brain type fat embolism syndrome from brain injury. Synthetical measure was adopted mainly using dexamethasone (20～80mg/d). Results 7 cases of brain type fat embolism syndrome complicated with fracture were cured in 1～7 days. Conclusions Sudden somnolence or coma that does not result from brain injure after limb fracturees in early stage can be diagnosed as brain type fat embolism syndrome. A synthetical measure should be adopted by mainly using dexamethasone (40～80mg/d) .
