The non-healing of malnutrition wounds is considered to be related to anemia and low protein, which can be alleviated through dietary adjustment, blood transfusion therapy and albumin infusion. 1. Dietary adjustment: If the wound does not heal due to malnutrition, under the premise of ensuring balanced nutrition, you can increase the amount of food rich in high quality protein to raise the level of albumin, such as milk, eggs, deep-sea fish, etc., and also increase the amount of soybean products, such as soybeans, black beans, peanuts, etc., and eat more fresh vegetables and fruits, such as oranges, spinach and tomatoes, etc., to promote the healing process. 2. Blood transfusion therapy: If the wound healing is affected by anemic malnutrition and the degree of anemia is relatively serious, blood transfusion can be used if necessary, and attention should be paid to the observation of any adverse reactions during the transfusion. At present, plasma and red blood cells can be transfused in component blood transfusion. 3. Transfusion of albumin: If the wound healing is affected by low-protein malnutrition, the patient should be given intravenous infusion of albumin while regulating the diet, paying attention to the history of allergy and observing the vital signs. It is recommended to go to the hospital in time, under the guidance of the doctor’s treatment, to avoid delaying the condition and causing other damages.
