A creatinine of more than 500 μmol/L usually requires dialysis treatment or preparation for dialysis treatment if there are no obvious contraindications. However, if the patient is old or has few complications, dialysis may be temporarily withheld.
When creatinine >500μmol/L, renal function has been seriously impaired, the calculated creatinine clearance is usually less than 15ml/min, and there may have been basically oliguria or even anuria, the blood volume of the body will rise sharply, the cardiac load is increased, and the likelihood of heart failure, hyperkalemia is very high, and the risk of cardiac arrest and sudden death is also increased.
Dialysis can filter out the excess water from the body and reduce the volume load; lower the blood potassium, maintain the blood potassium at the normal level, correct the metabolic acidosis, maintain the acid-base balance of the body and reduce the risk of death.
Patients with creatinine more than 500μmol/L are recommended to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
