During hip replacement, acetabular and femur bone preparation may cause bone marrow extravasation. Paradoxical fat embolism occurs when emboli pass from the pulmonary to the systemic circulation by either a patent foramen ovale or pulmonary capillaries. Impaired consciousness in the immediate postoperative period of orthopedic surgery frequently results from hypovolemia, anemia, or residual anesthesia. A high index of suspicion is required to consider the possibility of paradoxical fat embolism.
在髋关节置换术中，髋臼和股骨的准备过程可能导致骨髓外渗。当栓子通过卵圆孔未闭或肺毛细血管从肺循环进入体循环时，就会发生反常性脂肪栓塞。矫形外科手术后即刻意识障碍常因血容量不足、贫血或残留麻醉引起。需要高度怀疑反常性脂肪栓塞的可能性。
