Issues of patients with acute renal failure in the diet should be considered:
The supply of high quality protein: patients with acute renal failure oliguria appetite is poor, it is difficult to meet the requirements of high in calories.
Restrict intake of water: when oliguria, to strictly limit the variety of water intake to prevent fluid overload caused by acute pulmonary edema or hyponatremia dilution.
The moisture content of food is calculated, for example, 1 gram of raw protein 0.43 ml, 1 g of raw fat 1.07 ml, 1 g of raw carbon hydrates 0.55ml. To record the water intake and urine production, according to the excretion of bodily fluids to determine the daily intake, under normal circumstances, to follow the doctor's orders water.
Supply low-salt diet low sodium: used when oliguria, accompanied by edema, according to the determination of serum sodium, and without salt or low-sodium diet.
When hyperkalemia, to reduce the amount of potassium in the diet, avoiding foods that contain potassium, so potassium exogenous increase in aggravated hyperkalemia. Foods rich in potassium can be frozen, soaked in water or broth was discarded to reduce the potassium content.
As you can improve in the short term should be given a low-protein diet, gastrointestinal reactions were severe, intravenous fluids may be administered in a short period based glucose.
When polyuria, increased production of urine, blood urea nitrogen decreased appetite gradually improved, proper nutrition can accelerate the increase in body repair. Polyuria should pay attention to add water and electrolytes, about 1000 ml of water daily, intravenous rehydration, plus urine calculations first day. Note that giving vitamin preparations.
When the recovery period, serum creatinine and blood urea nitrogen decreased, while dietary protein may be gradually increased amino acid injection can be given if necessary. Injection containing amino acids isoleucine, leucine, lysine, methionine, valine, arginine, histidine, etc, it is worth noting that the BCAA should represent 40% to 50% essential amino acids Only in this way can help the synthesis muscle protein.
