The duration of human albumin infusion should be decided according to the situation of albumin in liver function index, and it can be stopped when the albumin rises to 30g/L in general. Human albumin is a human blood product and is used for the prevention and treatment of hypoalbuminemia, often in combination with diuretics. Normal human albumin is usually above 40g/L. When the albumin is below 30g/L, or when there are obvious symptoms such as generalized swelling, peritoneal effusion and pleural effusion, as well as patients with malignant tumors, human albumin infusion is required. Usually, the liver function should be rechecked after 3-5 days of use to observe the change of albumin content and the improvement of symptoms. If the albumin level rises to 30g/L, it can be stopped. Blood transfusion reactions may occur during the course of human albumin infusion, so pay attention to the observation during the drug administration and stop the drug as soon as the blood transfusion reaction occurs, and give timely and effective symptomatic treatment.
