Patients with renal failure need to pay attention to the following points in their care: First, the urine volume should be closely monitored, the decrease in urine volume suggests that the kidney function may be deteriorating, so the urine volume should be monitored daily. To avoid infection, infection may cause renal failure to worsen, so when the season becomes cold, we should ask patients to add more clothes, and usually when eating, especially in summer, we should pay attention to food cleanliness to avoid causing infectious diarrhea. Third, to take drugs regularly, the disease of renal failure can not be cured and requires long-term drug maintenance, the number and type of drugs taken are relatively large. If the patient is not very good compliance, it is very easy to miss the medication, so usually you should urge the patient to take the medication regularly. The condition of patients with renal failure is not static, it is gradually deteriorating, and the dosage of medication needs to be adjusted according to the condition and test results, so patients should be instructed to review regularly.
