Chronic kidney disease includes chronic nephritis, nephrotic syndrome, chronic pyelonephritis, chronic renal failure, etc. The disease is often prolonged and long-lasting, and some patients must be treated with hormones and immunosuppressants for a long time, with poor nutritional status and weak body resistance, becoming a high-risk group for various infections. Therefore, pay attention to daily preventive health care and avoid infection is a close concern for patients. 1, to have a calm state of mind Scientific research shows that panic, tension, anxiety and other emotions can lead to a decrease in body resistance, and even symptoms such as tachycardia, arrhythmia, increased blood pressure and loss of appetite. In fact, many chronic kidney patients have more or less accumulated experience in dealing with the disease, some patients have even experienced the test of kidney puncture, hemodialysis, kidney transplantation, etc., and already have good psychological quality, which are the prerequisites for the prevention of infectious diseases. 2, keep the living environment air circulation In the case of not very hot weather try not to open the air conditioning, or reduce the time to open the air conditioning, and in the morning and evening every day regularly open the window ventilation. Chronic kidney patients must regularly go to the hospital for review or hemodialysis treatment, should take into account their poor resistance, should be reduced to go out by public transport, avoid contact with unfamiliar people, especially to avoid a long stay in public places such as shopping malls, restaurants, etc. without ventilation. 3, to develop good personal hygiene habits should be appropriate use of antibacterial hand sanitizer, the back of the hand, fingers, nail grooves and other parts of the attention to comprehensive cleaning. Especially avoid rubbing eyes, picking nose, itching, etc. with unwashed hands. Hemodialysis patients with arteriovenous fistulae in the forearm should also pay attention to cleanliness to avoid local infection. Peritoneal dialysis patients with abdominal tunnels should insist on daily bathing to avoid skin or tunnel infections. The bedding should be tanned regularly, the room should be cleaned, and the floor should be mopped and scrubbed regularly with disinfectant. 4, pay attention to enhance their own immunity Many kidney patients with long-term loss of appetite, malnutrition, anemia and toxin retention due to kidney failure, these factors should be corrected as much as possible under the guidance of doctors. It is necessary to strengthen nutritional support in the diet, use erythropoietin to correct anemia, increase the dose of dialysis to ensure adequate dialysis, etc., in order to enhance the body resistance. It is important to have moderate amount of physical exercise and do more outdoor activities in parks and other ventilated environments. Attention should be paid to vitamin supplementation, if necessary, you can take appropriate amount of oral vitamin C, vitamin B complex and other drugs. 5, to adhere to the regular regular treatment of some nephrotic syndrome patients often must take prednisone and other hormonal drugs, kidney transplant patients to prevent rejection to take long-term cyclosporine and other immunosuppressive drugs, some people worry that the side effects of the drug itself will reduce their own resistance, increasing the chance of infection, so reduce the dosage of prednisone, cyclosporine and other drugs on their own, which is extremely undesirable. Because the drug dose and course of treatment is the original kidney disease does not relapse guarantee, the patient’s own drug reduction will lead to aggravation of the disease. 6, actively seek the guidance of specialists chronic kidney patients fever common causes are upper respiratory tract infections, tonsillitis, tracheobronchitis and bacterial pneumonia, etc., should pay attention to the treatment under the guidance of nephrologists. Because many cold medicines and antibiotics have different degrees of nephrotoxicity, often leading to aggravation of the original kidney disease or loss of residual kidney function; for patients with renal impairment, the dose and frequency of antibiotic use must be adjusted according to the renal function. In addition, different kidney diseases have different requirements and precautions in treatment, which need to be adjusted under the careful guidance of a specialist. For example, for chronic renal failure patients, more high protein intake is recommended in the diet of patients who have undergone hemodialysis and abdominal dialysis in order to improve their nutritional status; however, for those who are on non-dialysis conservative treatment, protein intake should still be limited in order to protect kidney function. In order to enhance resistance, we should eat more vegetables and fruits with high vitamin content; however, for patients with low urine and swelling, we should restrict water intake to avoid “watery”, leading to heart failure and pulmonary edema; for patients with renal failure, we should be alert to the possibility of fatal hyperkalemia caused by fruits such as orange and banana.
