Daily fluid intake during the oliguria phase was equal to the previous day urine volume plus stool, vomiting, and discharge volume, plus 500ml (for non dominant water loss minus endogenous water volume). Oliguric hyperkalemia is the main cause of death, to strictly limit the high potassium foods and drugs, active control of infection, to prohibit the importation of obsolete inventory blood. With 5% sodium bicarbonate solution to correct the metabolic acidosis and hyperkalemia, correct first aid measures. Adding normal insulin to the glucose solution at the quiescent point promotes glycogen synthesis and allows potassium to enter the cell. Application of 10% calcium gluconate 10 ~ 20ml intravenous injection can antagonize high potassium on myocardial toxicity and correct hypocalcemia.
Treatment of acute renal failure is the most effective measure is the use of dialysis therapy, including peritoneal dialysis; hemodialysis; pure ultrafiltration and (or) sequential ultrafiltration; continuous arteriovenous hemofiltration and continuous arteriovenous hemofiltration and hemodialysis; hemoperfusion; plasma exchange; adsorption type blood dialysis. The dialysis techniques have indications and contraindications, and their advantages and disadvantages. Choose according to the specific situation. Based on hemodialysis and peritoneal dialysis, peritoneal dialysis is simple, safe and economical. It is easy to be carried out in primary hospitals.
During the polyuria period,should attention to prevent dehydration, but the amount of fluid infusion should not be too much, otherwise the diuresis period will be prolonged. During the polyuria period, especially the electrolyte disorders, especially hypokalemia. One week after diuresis, the renal function gradually recovered, and the protein intake in the diet increased gradually, which was beneficial to the recovery of the organism and the repair and regeneration of the renal cells.
During the recovery period, not need special treatment, avoid use of nephrotoxic drugs. The operation and injury should be avoided during the recovery period. The pregnancy should be prohibited and the renal function should be regularly reviewed every 1~2 months.
