1, asked to see the pelvis deformation, as an orthopedic surgeon, should first rule out fracture at the pelvis, why not do a pelvic examination? Suspected of shock caused by pelvic fracture, we should carefully examine the pelvis, once it is clear that the pelvis is fractured, it is prohibited to do a specialist examination of the pelvis. Firstly it may become more bleeding and even cause death. The second can make the already deformed pelvis, deformation more serious. 2, ask what kind of situation should be highly suspected of pelvic fracture? (1) unequal length or rotational deformity of the two lower limbs without lower limb injury; (2) unequal distance between the umbilicus and the anterior superior iliac spine on both sides; (3) widening, displacement or deformation of the pubic tuberosity gap on both sides; (4) asymmetric shape of the posterior aspect of both sacroiliac joints; (5) pelvic deformation visible to the naked eye 3. To observe the volume and color of urine when infusing large amount of fluids, and to determine whether there is rupture of urethra and bladder by lowering the catheter. 4, ask you as orthopedic surgeons, and the patient does not have diarrhea and other gastrointestinal symptoms, why do you need anal examination? 5. You mentioned open pelvic fracture, what is open pelvic fracture and is it very serious? An open pelvic fracture is a fracture that is connected to the rectum or vagina or through the skin to the outside world, and is called a fatal pelvic fracture. The mortality rate is close to 50%. 6. ask why the fracture should be fixed with an external fixation brace without knowing the exact circumstances of the fracture? Early stabilization of the pelvis is the most reliable way to reduce bleeding, and external fixation frame is more reliable. 7.Q: What should be done if neither anti-shock pants nor external fixation can control continued bleeding? Trans-femoral artery cannulation for iliac arteriography should be performed. If arterial bleeding is found, embolization of the bleeding vessel should be performed immediately.
