(2) limit the intake of water: during the oliguria period, it is necessary to strictly limit the intake of various water to prevent excessive body fluid and cause acute pulmonary edema or dilute hyponatremia. The water content of food should be calculated as 1 grams of protein, 0.43 ml of water, 1 grams of fat, 1 grams carbohydrates water 1.07 ml, 0.55 ml of raw water. To record the amount of drinking water and urine, according to the body fluids to determine the amount of daily intake, under normal circumstances, to comply with the doctor's instructions drinking.
(3) polyuria, urine volume increased, blood urea nitrogen decreased, appetite gradually improved, appropriate increase nutrition can accelerate the body repair. Polyuria period should pay attention to add water and electrolytes, daily drinking water about 1000 ml, intravenous rehydration, plus the previous day's urine volume calculation. Pay attention to vitamin preparations.

Amino Acid Injection contains isoleucine, leucine, lysine, methionine, valine, arginine, histidine, notably branched chain amino acids should be accounted for 40% to 50% of the essential amino acids, the only way to improve the synthesis of muscle protein.
(5) the supply of low salt and low sodium diet: oliguria, accompanied by edema, low salt, no salt or low sodium were used according to the determination of serum sodium diet.

Such as when mild heat supply should be easy to digest carbohydrates, the wheat starch noodles, fruit, cereal, cookies or other snacks wheat starch, add a small amount of rice soup or porridge, to reduce the intake of protein and non essential amino acids, reduce the burden on the kidney, prevent nitrogen retention aggravate. Try to give the protein of animal protein, the lowest protein with high biological principle, to determine the daily supply of protein according to the amount of urea nitrogen. Appropriate amount of lean meat, fish, chicken, shrimp and other animal protein alternately used to adjust the patient's taste.
(7) if in the short term can be improved, should be given a low protein diet, gastrointestinal reactions are severe, short-term intravenous rehydration may be given, mainly to glucose.
