Liver injury is categorized into closed injury and open injury, and the patient’s body often shows pale color and cold sweat. 1. Closed injury: the disease is characterized by violence directly on the liver, but there is no wound on the body surface. When the liver is only superficially lacerated, the patient’s bleeding is small and can be stopped on its own, and the patient may be asymptomatic or less symptomatic. If the liver is deeply lacerated, the patient may bleed profusely and exhibit pallor, cold sweats, cold extremities, rapid pulse, and decreased blood pressure. Mild peritoneal irritation signs may appear in the hemoperitoneum, causing abdominal pain, abdominal muscle tension, pressure and rebound pain. 2. Open injury: the patient’s physical manifestation is a wound in the liver area, and there is a large amount of blood outflow. Some patients also have other symptoms such as pain in the liver area, pallor, rapid pulse and drop in blood pressure. In addition to the above symptoms, some patients with liver injury may show yellow staining of the skin and sclera as well as loss of appetite, aversion to greasy food, nausea and vomiting. It is recommended to consult a doctor for a clear diagnosis and targeted treatment.
