The human body needs to transfuse albumin to be input in the condition of serious infection, shock, serious damage of liver function and so on, and to go to the regular hospital for treatment. 1. Serious infection: As the body is seriously infected, it may lead to a decrease in the content of colloid solution, resulting in the symptom that the amount of serum albumin is too low, and at this time, it is necessary to transfuse albumin to replenish it. 2. Shock: If the patient is in shock due to a large burn area or excessive blood loss, albumin needs to be supplemented in time to increase the patient’s plasma osmotic pressure, and also to increase blood volume. 3. Serious impairment of liver function: when the patient is in the advanced stage of liver cirrhosis, it may cause severe hypoalbuminemia, which requires timely albumin input. When allergic reaction occurs, such as fever, dizziness and other symptoms, the input needs to be stopped immediately to avoid anaphylactic shock. If the patient is severe anemia or heart failure, the input of albumin should be prohibited to avoid aggravating anemia. It is forbidden to use the drug when there is precipitation or foreign matter. Albumin needs to be used in a standardized way under the guidance of a professional doctor.
