The physical examination results are as follows: BP of 90/60 mmHg, P of 110 beats/min, T of 37 °C, and a normal cardiopulmonary examination. The FAST results suggest that there is a small amount of free fluid in the abdominal cavity, suspected shifting dullness, weak bowel sounds, slight abdominal distension, restricted abdominal breathing, full abdominal tenderness and muscular tension with rebound tenderness; the Hb level is 10 g/l, and WBC is 12 × 10^9/L.

The examination results are as follows: obvious swelling, cyanoderma and numbness on the right toe, and poor toe movement are present, capillary filling still exists after the splint is removed, the right leg is quite swollen, the skin temperature is high and blisters appear on the skin.
