Not all patients with high creatinine need dialysis, there are indications for dialysis, and dialysis can be done when the indications are met. Clinical guidelines suggest that patients with chronic renal failure should be dialyzed when their creatinine is greater than 707 μmol/L, but this indicator can be relaxed in clinical practice. For patients without underlying diseases, the body is relatively good in all aspects, can be appropriately relaxed indicators. But for patients with underlying diseases, the standard of dialysis should be lowered appropriately, for example, for diabetic patients, maybe the creatinine value is not very high, but there is severe edema, and diuretics are ineffective, there is hyperkalemia, severe acidosis and other life-threatening, this time dialysis is a life-saving method, need to be performed in emergency dialysis. So dialysis has indications, not just creatinine as a criterion, for patients with high creatinine value, whether to dialyze or not should be decided according to their own situation.
