Hemodialysis for Acute Kidney Failure

Medically reviewed by Last updated on Feb 6, 2023.

Hemodialysis is a procedure that uses a machine to do the job of your kidneys. The machine pumps your blood through a dialyzer, or artificial kidney. The dialyzer filters fluid, salts, and waste from your blood. Once they are removed, clean blood from the dialyzer returns to your body through a vein. Acute kidney failure happens when your kidneys suddenly stop working. Failure happens quickly, within hours or days.


Call 911 for any of the following:

  • You have sudden chest pain or trouble breathing.
  • You are breathing fast or have a fast heartbeat.
  • You feel confused, dizzy, or lightheaded.

Seek care immediately if:

  • Blood soaks through your bandage.
  • The skin around your fistula or graft is painful, hot, red, or swollen.
  • You cannot eat or drink because you are vomiting.
  • Your fingers are blue or pale, or they feel cool to the touch.

Contact your healthcare provider if:

  • You have a fever.
  • You do not feel a buzzing sensation in your fistula or graft.
  • You have chills, cough, or feel weak and achy.
  • Your skin itches or you have a rash.
  • You cannot make it to your follow-up or dialysis visit.
  • You have questions or concerns about your condition or care.


  • Vitamins may help prevent anemia (low level of red blood cells).
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.


Your healthcare provider will tell you what changes you need to make to the foods you eat. A dietitian can help you plan meals.

  • Eat foods as directed. You may need extra calories or protein. Limit potassium, phosphorus, and sodium (salt). Talk to your healthcare provider or dietitian for help or more information about nutrition.
  • Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. Keep a record of how much liquid you drink each day. Count ice cubes, soup, gravy, gelatin, and popsicles. Limit caffeine.
  • Keep your mouth moist. Suck on hard candy or lemon wedges, or chew gum.
