Dosage and Administration:(1) in patients with supplementary energy for some reason can not eat or eat to reduce, generally 25 percent to intravenous glucose injection, and at the same time to add body fluids. According to the amount of glucose required for the calculation of heat. (2) total parenteral nutrition therapy is the treatment of glucose the most important energy supply material. In the non-energy protein, fat and glucose energy supply ratio at 2:1. Specific amount based on the clinical need for heat. According to the needs of the volume of fluid infusion, glucose can be prepared for the 25% to 50% of the different concentrations and, if necessary, adding insulin, every 5 ~ 10g glucose-insulin-formal accession to the unit 1. Due to the normal application of hypertonic glucose solution, the more provocative vein, and to be fat emulsion infusion, the large selection of general intravenous drip. (3), hypoglycemia, can re-use Xianyu 50% glucose injection 20 ~ 40ml intravenous injection. (4) of hunger ketosis, severe cases, the application of 5% to 25% of the intravenous injection of glucose, glucose 100g per day can be brought under control the disease. (5), isotonic water loss of water to give 5% glucose injection by intravenous drip. (6) Application of hyperkalemia 10% to 25% injection every 2 ~ 4g glucose plus 1 unit regular insulin infusion can reduce serum potassium concentration. However, the only treatment so that the extracellular potassium into cells, the body of the total potassium content unchanged. If we do not take potassium row, there is still the possibility of the recurrence of hyperkalemia. (7) organizations hypertonic dehydration solution (generally 50% glucose injection) rapid intravenous injection of 20 ~ 50ml. However, the role of short-lived. Clinical should be taken to avoid high blood sugar, with little current. Peritoneal dialysis fluid for regulating the osmotic pressure, 50% glucose injection 20ml is allows 10g glucose 1L peritoneal dialysis fluid osmotic pressure to raise 55mOsm/kgH2O.
