The number of patients on regular dialysis in the Dialysis Center clinic will soon exceed 250. Most patients can significantly improve their uremic symptoms and anemia with regular dialysis and erythropoietin and iron supplements. However, the prevalence of hyperphosphatemia in patients does cause a headache. Although we often find time to give them some knowledge about this, the results are not satisfactory for various reasons (either they can’t remember, they don’t have confidence, or they don’t have money to buy drugs after the lecture). To control hyperphosphatemia, it is also necessary to intervene in many ways, such as diet, medication and dialysis. That old professor patient is a good example, but unfortunately not everyone has such a blessing, like the professor has a caring old partner, so patients and friends still have to learn to understand some of the truth, in order to better cooperate with doctors. A few points to pay attention to: 1, phosphorus is mainly excreted through the kidneys, kidney function decline is the most basic factor of high blood phosphorus. 2, dialysis patients need to ensure a certain protein intake, and each gram of protein contains about 12-16mg of phosphorus, the daily phosphorus intake is about 800-1200mg (calculated with protein intake 1-1.2g/kg.d). 3, active vitamin D can make the intestinal absorption of phosphorus increased, so that the affinity of phosphorus and its binding agent decreased by 30-40%. 4, dialysis removes limited phosphorus conventional hemodialysis removes about 800mg of phosphorus each time. Therefore, for regular dialysis patients: 1, to control their mouth, avoid excessive intake of high phosphorus food 2, to ensure the time of dialysis, emphasizing adequate dialysis (at least 12 hours per week) 3, to pay attention to the correct medication, choose the appropriate phosphorus-lowering drugs (aluminum hydroxide, calcium carbonate, sevelamer, lanthanum carbonate) 4. To carry out the doctor’s orders and avoid unauthorized drug changes.
