(1) The room should be irradiated with ultraviolet light for 30 minutes twice a day before dialysis; the patient’s bed, table, walls and floor should be wiped with 2% Lysol solution; the patient’s bed sheet and clothes should be changed once a day; the room should also be ventilated and the Lysol foot pad should be placed in front of the door. (2) The aseptic technique must be strictly implemented when preparing dialysis fluid and dialysis operation; the dialysis fluid injection tube should be closed and changed once a day. (3) Closely observe the color and clarity of the dialysis fluid during the dialysis process, and regularly send it for bacterial culture and drug sensitivity test. (4) Observe the patient’s body temperature and abdominal pain, and give antibiotic treatment according to medical prescription if there is infection. (5) Patients with abdominal pain can adjust the position of dialysis tubing, the temperature, flow rate and pH of dialysis fluid appropriately. For those with abdominal distension, which may be caused by reduced intestinal peristalsis, apply heat or gently massage the abdomen; encourage the patient to eat more fiber-rich foods and, if necessary, give epifriedrine, neostigmine and other drugs to relieve symptoms. (6) Do a good job of protective isolation, live in a single room, strict accompanying, visiting system to prevent cross-infection. Wash hands before entering the room and wear a good mask and hat. (7) Do a good job of monitoring. Daily weight, pulse, central venous pressure should be measured, accurate records of 24-hour in and out volume, good nursing records for critically ill patients, and also detailed records of the time, volume and residence time of dialysis fluid every time it enters and leaves the abdominal cavity, regularly send drainage fluid for various electrolyte and sugar checks, and observe whether there is dehydration or water retention, high sodium, high sugar, low potassium, high potassium and other complication symptoms during dialysis, and promptly notify the physician for timely adjustment. (8) Diet: Supplement high-calorie diet with high bioeffective protein such as milk, fresh eggs, beef, etc. Daily calorie intake should be more than 35kcal/kg body weight. High phosphorus diet should be avoided. For those with rapid weight gain, swelling or hypertension, water and sodium intake should be restricted. (9) Strengthen basic nursing care: do morning and evening nursing, oral and skin care, and turn patients who cannot take care of themselves and have difficulty moving regularly to prevent bed sores and unnecessary infections. (10) Care of dialysis tubing: Before daily dialysis, the catheter and its skin outlet should be disinfected with complex iodine solution and covered with dressing. And keep it clean, dry, and change it immediately if it is wet. Carefully observe the dialysis tubing outlet for blood leakage, fluid leakage, redness and swelling, etc. If there is any of these conditions, treat accordingly. If the patient needs to take a shower, the dialysis tubing can be wrapped with plastic before showering, and after showering, the skin around it can be gently wiped dry, then disinfected with complex iodine and rewrapped, but it is not advisable to take a bath to avoid peritonitis.
