After the patient develops the symptom of ultrafiltration of abdominal dialysis with excessive water, the symptom can be relieved by proper intake of water and salt, use of diuretics, use of hypertonic dialysate, and adjustment of the dialysis regimen. 1. Appropriate intake of water and salt: By estimation, using the ultrafiltration volume of the previous day’s peritoneal dialysis plus the patient’s urine volume, plus 500 ml, the amount of water to be consumed on the next day can be derived, and the water-containing food should also be included in the calculation, so as not to ingest too much water, and the salt content of the intake of less than 3 grams per day, and the other food with a high content of salt as little as possible. 2. The use of diuretics: patients use diuretics, through the way of urination, to eliminate excessive water in the body, can alleviate the symptoms of ultrafiltration of abdominal dialysis accompanied by water, need to be used under the guidance of a doctor, avoid self-medication. 3. Using hypertonic dialysis solution: using hypertonic dialysis solution, such as 4.25% dialysis solution, glucose concentration of 2.5%, etc., can improve the ultrafiltration of abdominal dialysis and eliminate edema, and need to be used under the guidance of doctors. 4. Adjust the dialysis program: due to the different physique of patients and different peritoneal transport characteristics, you can determine the characteristics of peritoneal transport, let the doctor make a suitable dialysis treatment program for the patients, adjust the number of dialysis exchanges and retention time, which can increase the ultrafiltration of peritoneal dialysis. If patients with abdominal dialysis experience uncomfortable symptoms, it is recommended that they go to regular hospitals in time, and standardize their treatment under the guidance of doctors.
