Elevated blood pressure after hemodialysis may be caused by complications due to chronic kidney disease or increased vascular tone, etc. It can be treated by oral medication, intravenous medication, and lowering blood flow to reduce blood pressure. 1. Oral drugs: patients with elevated blood pressure after dialysis are often related to the activation of RAS after the reduction of body fluids, so patients with elevated blood pressure can be given drugs such as captopril or cloxartan. 2. Intravenous medication: For patients with severe elevated blood pressure, if sublingual nifedipine tablets or nitroglycerin cannot lower the blood pressure, then nitroglycerin may need to be given intravenously. 3. Reduce the blood flow: If the patient’s blood pressure rises after dialysis, then the blood flow can be reduced and the ultrafiltration speed can be slowed down during the next dialysis, and then the patient’s blood pressure can be observed again. If the patient’s blood pressure rises after dialysis, it is recommended to go to the regular hospital in time, and standardize the treatment under the doctor’s guidance.
