Indication: Vitamin drugs. Suitable for 1. Prevention and treatment of scurvy, and can also be used as an auxiliary treatment for various acute and chronic infectious diseases and purpura. Large doses of intravenous injection are used for Keshan disease and rescue in cardiogenic shock. 2. Treatment of chronic iron poisoning: Vitamin C promotes the chelation of iron by deferoxamine, which accelerates the excretion of iron. 3. Treatment of idiopathic methemoglobinemia 2. 4. The following situations increase the need for vitamin C: (1) Patients undergoing chronic hemodialysis, gastrointestinal diseases (long-term diarrhea, gastric or ileal resection), tuberculosis, cancer, ulcer disease, hyperthyroidism, fever, infection, trauma, burns, surgery, etc. (2) Patients who receive parenteral nutrition due to strict control or selection of diet, malnutrition, sudden weight loss, and during pregnancy and lactation. (3) When using barbiturates, tetracyclines, salicylates, or vitamin C as a urinary system acidifier.
