Albumin is a blood product, so it is necessary to sign an informed consent form for albumin transfusion. Risks can also occur during albumin infusion, and the main complications and risks that may occur with albumin infusion are: 1. Allergic reaction or febrile reaction may occur, causing the patient to have chills and fever, nausea and vomiting; 2. albumin infusion may be infected with bacteria, viruses or other pathogens, such as hepatitis B, hepatitis C, AIDS, etc; 3. During the infusion of albumin, if too much is fed in too quickly, it may lead to an increase in blood volume, resulting in a heavier burden on the heart and kidneys; 4. As albumin preparations are not depurated of vasoactive substances such as kinins during processing and extraction, it may cause a drop in blood pressure and accidents; 5. If patients use purchased albumin, in order to ensure the safety and effectiveness of patient’s treatment, we hope that patients and their families will buy albumin produced by regular manufacturers in regular pharmacies. Since hospitals have no way to guarantee the quality of patients’ purchased albumin, and they do not have professional testing equipment and ability, they are not responsible for the adverse problems caused by the quality of purchased albumin. Albumin infusion has the above risks, so it is necessary to sign an informed consent form.
