High low pressure after hemodialysis is related to dialysis insufficiency, calcium and phosphorus metabolism disorder, and dialysate concentration.
1. Inadequate dialysis: it means that the body still has excess water, including obvious edema and hidden edema, and sodium retention is one of the causes of hypertension. The treatment is to increase the ultrafiltration volume, adjust the dry weight downward, and the speed should be slow to avoid complications such as hypotension and cramps.
2. Calcium and phosphorus metabolism disorder: most regular dialysis patients will have low calcium/high calcium, high phosphorus and high PTH, which cause vascular calcification, decreased elasticity, poor vascular compliance, and cause elevated blood pressure. Calcium acetate, lanthanum carbonate, osteotriol, cinacalcet and other drugs are used according to biochemical indexes to correct calcium and phosphorus metabolism disorder.
3. Concentration of dialysis fluid: such as calcium, potassium, sodium concentration can have an effect on blood pressure. Adjustable sodium is used in dialysis, and low-calcium dialysate can be used in patients with persistent hypertension.
If patients have high blood pressure after hemodialysis, it is recommended to go to regular hospitals in time, and standardize the treatment under the guidance of doctors.
