There is no uniform standard for how much protein should be transfused below. Some people have relatively high plasma albumin and receive protein transfusions, while others have very low protein levels and do not receive protein transfusions. This is related to the local medical environment, the economic status of the family, and whether the patient’s family requests protein transfusion. At present, many people take protein transfusion as a kind of nutritional support, but in fact, protein transfusion is not nutritional support, there are certain indications for protein transfusion, and now protein transfusion is abused, the need for protein transfusion is not protein transfusion, do not need protein transfusion but protein transfusion. The actual time when the protein is transfused needs to be determined by the doctor according to the patient’s condition and the degree of plasma albumin, not simply the low plasma albumin should be transfused.
