Creatinine 700μmoI/L, if there is no obvious loss of appetite, nausea, vomiting, not accompanied by hyperkalemia and heart failure, and the volume of urine is still normal, this time can be temporarily not dialysis. Creatinine of 700μmoI/L indicates that the detoxification ability of the kidney is very low, and for chronic renal failure, it has entered the uremic phase. Once entering the uremic phase, hemodialysis is generally recommended for treatment. However, if the patient’s willingness to dialysis is not very strong, especially if they are resistant to dialysis, you can observe the patient’s clinical symptoms and blood indicators before deciding on the next treatment plan. Observe whether the patient has obvious gastrointestinal symptoms, such as nausea, vomiting, and loss of appetite. In addition, observe whether the patient has normal urine output, whether there are obvious symptoms of heart failure such as chest tightness, breath-holding, and nocturnal paroxysmal dyspnea, and whether there is hyperkalemia by performing electrolyte examination. If the patient does not have any of the above mentioned conditions, he may not be given hemodialysis treatment for the time being, but can be prepared for long-term hemodialysis by performing intravenous fistuloplasty or internal jugular vein placement.
