The danger period for hepatic contusion is usually about 1 week, and the exact number of days depends on the type and severity of the contusion and the amount of bleeding. A hepatic contusion is a traumatic lesion in which the liver parenchyma has been damaged by an external factor and the hepatic envelope is still intact. There is some risk of sudden worsening of the injury, increased bleeding and hematoma, or complete hepatic rupture may occur. If the contusion is small, the bleeding is small enough to cause hepatic rupture, the heart rate and pulse are stable, and there are no obvious symptoms such as abdominal pain or shock, the patient can be closely observed and conservatively treated, and can usually pass the danger period in about 1 week. If there is a large amount of bleeding, abdominal pain, a large amount of fluid in the abdominal cavity, heart rate, pulse instability, hemorrhagic shock and other manifestations, consider the rupture of the pericardium, most of them need emergency surgery to stop bleeding, blood transfusion, and those who recovered successfully after the surgery can usually get to the stable stage within 10 days. Hepatic contusion should not be taken lightly, close observation and monitoring of signs, strict bed rest, avoiding activities, abnormal symptoms promptly notify the physician.
