A 30 year old man had road traffic accident and sustained fracture of femur. Two days later he developed sudden breathlessness. The most probable cause can be:: (A) Pneumonia, (B) Congestive hea failure, (C) Bronchial asthma, (D) Fat Embolism
Answer is D. Onset of breathlessness two days after fracture of long bone suggests the diagnosis of fat embolism. Ref: Greenberg's Text-Atlas of Emergency Medicine By Michael I. Greenberg, 2005, Page 672
