One month of dialysis creatinine rose 170μmol/L may be poor dialysis adequacy, poor patient self-management and so on. In addition, it is also necessary to be alert to whether there are secondary infections. 1. Poor dialysis adequacy (1) The assessment of dialysis adequacy in dialysis patients is generally based on kt/v (urea clearance index), i.e., the level of urea before and after dialysis, which is calculated according to the formula, and the patients with hemodialysis should increase the number of dialysis sessions, increase the number of perfusion sessions, and the number of hemofiltration sessions, etc., which can be improved to a certain extent after the assessment of the dialysis adequacy. (2) In addition, if the patient is on peritoneal dialysis, the length of dialysis can be increased or the patient can be transferred to hemodialysis if necessary to increase the dialysis adequacy. 2. Poor patient self-management: although dialysis can be detoxified, patients should also pay attention to dietary control, do not eat a lot of high-protein food, excessive dietary intake, can also lead to the occurrence of a significant increase in blood creatinine, dialysis, as a dialysis method, can not completely cure the disease, but only to alleviate, and improve the quality of life. Regardless of the cause of creatinine elevation, should be taken seriously, it is recommended to regular hospitals, identify the cause, and follow the doctor’s instructions for treatment.
