What does "da dan bai" mean?

　　In clinical practice, "da bai dan" (literally "beating protein") generally refers to the administration of human serum albumin, which helps patients supplement their body's albumin levels and is primarily used to treat hypoalbuminemia.

　　Human serum albumin is an important protein in the human plasma that helps maintain plasma colloid osmotic pressure, transport nutrients in the blood, and alleviate edema. In certain disease states, such as nephrotic syndrome, cirrhosis, severe burns, major surgery, blood loss, trauma, or shock caused by burns, patients may experience significant albumin loss or insufficient synthesis. In such cases, administration of human albumin may be necessary to correct hypoalbuminemia and improve the patient's condition.

　　Administration of human serum albumin is usually performed via intravenous drip or intravenous push injection under the guidance of a physician, to ensure that the dosage and rate of infusion are appropriate for the patient's specific condition. During the infusion process, the physician will closely monitor the patient's response, and if adverse reactions such as chills, fever, facial flushing, rash, nausea, or vomiting occur, the infusion will be promptly discontinued and appropriate measures taken.

　　Patients receiving human serum albumin should strictly follow the dosage and infusion rate prescribed by their physician and should not adjust these themselves. Excessive infusion may lead to adverse effects such as dehydration and increased circulatory load.
