Kidney Dialysis Care

Usually, before your first hemodialysis, you will have some sort of tubing attached to a large vein to make blood flow from your body to the machine and back more easily. If you will be on hemodialysis for a long time, you may have had surgery to create a shunt or a fistula, which makes access to a large vein easier. Fistulas may need as long as 2–3 months to fully heal before they can be used. They are not used if the treatment is temporary. They are typically created many months before hemodialysis begins.

Other things that will happen before your hemodialysis are:

• Weight, blood pressure, and temperature are taken.
• Topical anesthetic (a pain-numbing medicine) is usually applied to the area of needle insertion, if needle insertion is needed.
• Heparin is given to prevent blood clotting.

You will be given a topical anesthetic.

Hemodialysis is done at a dialysis center or hospital. It may be done at home with assistance.

During the procedure, blood is filtered through an artificial kidney machine, called a dialyzer. The blood travels from your body to the machine through tubes inserted into a large vein in your body. Once the blood is filtered in the machine, it travels back into your body through another tube.

Hemodialysis is usually done three times a week. Each treatment can last anywhere from 2-4 hours. The specific time needed depends on a few factors:

• How much kidney function remains
• How much fluid weight gain has occurred since the last treatment
• Amount of waste in the body
• Body size
• Level of salts in your body, such as sodium, potassium, and chloride

In general, hemodialysis does not cause pain. You will not feel the blood exchange. There may be some temporary discomfort with the insertion of the needle or tube.

Your blood pressure will be monitored. Once the procedure is complete and blood pressure is stable, you are free to continue daily activities.

Be sure to follow your doctor's instructions . There are some special considerations:

Certain dietary guidelines should be followed. This will help to maintain overall health and optimize treatment effects. Talk to your doctor about your specific dietary needs.

Your doctor may give you various medicines. These include, but are not limited to:

• Blood pressure medicines
• Calcium supplements or multivitamins
• Phosphorus binders-to lower phosphorus levels in the blood
• Diuretics-to remove excess fluid
• Stool softeners or laxatives-to prevent or treat constipation, which can be caused by decreased fluid intake
• Iron supplements-to increase iron intake, which is important for production of red blood cells
• Medicines to stimulate the body to produce more red blood cells
