Acute renal failure, i.e., acute kidney injury, first attention should be paid to find the cause of acute renal failure and then give appropriate treatment. Its treatment includes early etiologic intervention therapy, nutritional support therapy, complication therapy and renal replacement and recovery therapy.
1. Early etiologic intervention therapy: the reversible causes should be corrected as soon as possible. This includes performing fluid rehydration and volume expansion, improving hypoproteinemia, and relieving urinary tract obstruction. If secondary to glomerulonephritis, etc., glucocorticoids such as prednisone can be used as prescribed by the doctor.
2. Nutritional supportive therapy: provide protein and other nutritional supply through gastrointestinal tract or vein, and restrict the intake of sodium and potassium salts as appropriate.
3. Treatment of complications: Vital signs such as temperature and electrolyte changes should be closely monitored. If hyperkalemia occurs, stop using potassium-containing drugs and use calcium gluconate, calcium polystyrene sulfonate and other drugs as prescribed by the doctor for treatment. In addition, if metabolic acidosis and other complications occur, they should be corrected in time.
4. Renal replacement therapy: including peritoneal dialysis therapy, intermittent hemodialysis therapy and so on.
5. Treatment during the recovery period: mainly to maintain water-electrolyte and acid-base balance, as well as to prevent and control various complications.
Acute renal failure patients are recommended to seek medical treatment in regular hospitals in time for targeted treatment.
