The most common complications of liver trauma include shock, multi-organ failure such as liver failure and renal failure, gastrointestinal bleeding and so on. 1. Shock: patients with liver trauma are often accompanied by hemorrhage, which can be manifested as pale, rapid pulse, restlessness, indifference, etc. This is the shock manifestation caused by more bleeding. In the case of severe rupture of liver combined with rupture of large blood vessels such as inferior vena cava and hepatic portal vein, the patient may die in a short time due to hemorrhage. 2. Liver and kidney failure: acute ischemia of liver tissue due to massive bleeding can easily lead to acute liver failure, while massive bleeding can also lead to a sharp drop in renal tissue perfusion, thus causing renal failure. 3. Gastrointestinal bleeding: hematoma will be formed after bleeding from liver trauma, when hematoma exists for a long time and secondary infection can lead to secondary liver abscess, at this time there will be high fever, chills, pain in the liver area and other manifestations. If the hematoma is connected to the biliary tract, there may be gastrointestinal bleeding such as vomiting blood and black stools. Hepatic trauma should be consulted promptly to avoid life-threatening hemorrhage.
