At the same time should consider the use of glucose and sodium chloride dosage: one. The amount of glucose use: 1. Patients with supplementary energy consumption reduction for some reason or can not eat, can be generally 10% to 25% of the intravenous infusion of glucose injection, and at the same time to add body fluids. According to the amount of glucose required for the calculation of heat. 2. Glucose total parenteral nutrition therapy is the treatment of the most important energy supply material. In the non-energy protein, fat and glucose energy supply ratio at 2:1. The amount of energy in accordance with the specific requirements of clinical decisions. According to the needs of the volume of fluid infusion, glucose can match 25% to 50% of the different concentrations and, if necessary, plus insulin, glucose every 5 ~ 10g regular insulin plus 1 unit. As the products hyperosmotic solution often applied to a larger vein irritating, and infusion to be fat emulsion, it is generally a better choice of the Ministry of large vein, such as the subclavian vein, internal jugular vein and so on. 3. Hypoglycemia, can re-use Xianyu 50% glucose injection 20 ~ 40ml intravenous injection. 4. 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. Water loss: loss of isotonic given 5% glucose injection by intravenous drip. 6. Application of hyperkalemia 10 to 25% of the injection, each 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. Organization of 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. Dialysis solution is glucose concentrations increased every 1% increase the osmotic pressure 55mOsm/kgH2O. II. The amount of sodium chloride use: 1. Hyperosmolar hyperosmolar water loss when water loss in patients with brain cells and increase the concentration of cerebrospinal fluid penetration, so that if the treatment of plasma and extracellular sodium concentration and rapid decline in infiltration levels can be caused by cerebral edema. It is generally believed that in the beginning of the treatment within 48 hours, the plasma concentration of sodium per hour fell less than 0.5mmol / L. If there is shock patients should be Xianyu sodium chloride injection, and, where appropriate, add gel, the shock to be corrected, sodium> 155mmol / L, plasma concentrations of infiltration> 350mOsm / L, could be hypotonic 0.6% sodium chloride injection. To be the infiltration of plasma concentrations of <330mOsm / L, using 0.9 percent sodium chloride injection. Rehydration total based on the following formula, as follows: the required amount of fluid (L) = [sodium concentration (mmol / L) -142] × 0.6 × weight (Kg) sodium concentration (mmol / L) the first day of general Supply and a half, the margin after 2 to 3 days of supply, according to the heart and lung functions of adjusting, as appropriate. 2. Isotonic dehydration of the principle of giving isotonic solution, such as 0.9% sodium chloride injection fluid compound sodium chloride injection, the However, the above-mentioned solution of chlorine concentration was significantly higher than that of plasma, can be caused by the use of a large number of separate high-hyperlipidemia, it can be 0.9% sodium chloride injection of sodium bicarbonate, or 1.25 percent, and 1.86% (1/6M) sodium lactate to the 7:3 ratio after the preparation supplies. The latter chlorine concentration of 107 mmol / L, and may correct the metabolic acidosis. Weight or volume of supply can be calculated hematocrit, as a reference. calculated according to weight: The amount of fluid (L) = (weight loss (kg) × 142) / 154; according to the hematocrit calculation: The amount of fluid (L) = (actual hematocrit - the normal hematocrit × weight (kg ) × 0.2) / normal hematocrit. Normal hematocrit 48% of men and women 42%. 3. Low permeability and low permeability of severe water loss and water loss, the brain cells to reduce the solute to maintain the cell volume. If so that the treatment of plasma and extracellular sodium concentration and penetration of the rapid rebound in concentration can be caused by brain cell damage. It is generally believed that when sodium less than 120 mmol / L, so that the treatment increased the speed of sodium per hour in 0.5 mmol / L, an hour less than 1.5 mmol / L. When sodium less than 120 mmol / L or when the central nervous system symptoms, they can give 3% to 5% sodium chloride injection slow drip. General requirements for 6 hours in the concentration of sodium will be increased to 120 mmol / L or more. Make up the amount of sodium (mmol / L) = [142 - actual sodium concentration (mmol / L)] × weight (kg) × 0.2. Sodium to be increased to 120 ~ 125mmol / L or more, would be able to isotonic solution or, where appropriate, by adding isotonic solution hypertonic glucose injection fluid of 10% sodium chloride injection. 4. Alkalosis to give low-0.9% sodium chloride injection fluid compound sodium chloride injection (Ringer's solution) 500 ~ 1000ml, according to later decide the amount of alkalosis.
