How is acute hyperphosphatemia treated?
The best treatment is avoiding acute hyperphosphatemia in the first place. Sodium phosphate bowel cleanses should be avoided, especially in patients with CKD and abnormal gut motility. Once the patient has hyperphosphatemia, the focus should be on maintaining kidney function to prevent accumulation. IV fluids should be started if the patient can tolerate them. Insulin can shift phosphorus into the cells, though it is unclear if this is beneficial. If the patient has kidney failure, consideration should be given to dialysis.
