What is hemodialysis?

Hemodialysis is a machine that filters wastes, salts and excessive fluid from your blood when your kidneys are not functioned to this work. Hemodialysis mainly deals with the micro molecule toxins in the blood, including BUN, creatinine, sugar, electrolyte and water.

What are the functions of hemodialysis?

Hemodialysis is g process that uses man-made membrane to play the following roles:

● Remove small sized wastes in the blood, such as urea, creatinine, BUN etc.

● Filter out the excessive water from the body.

● Keep the balance of electrolytes in the blood.

What are the side effects of dialysis?

Hemodialysis is used to prolong life for many people, but life expectancy for people who need hemodialysis it still much less than that for the general population, if the patient just takes this therapy only. You may experience the following side effects or complications after or during the hemodialysis.

- muscle cramps

- itching

- sleep problems

- low or high blood pressure

- fluid overload

- bone disease

- anemia

- Inflammation of the membrane surrounding the heart

- Infection

- High potassium levels

- Depression

- Amyloidosis

What are the features of hemodialysis?

- Hemodialysis only removes the micromolecule wastes in the blood.

- It is usually used in the following conditions: acute kidney failure, chronic kidney failure, acute poisoning, serious imbalance of water, electrolyte, uric-acid, severe acute pancreatitis, hepatic coma, psoriasis, hyperbilirubinemia.

What types of hemodialysis are there?

There are mainly 4 types of hemodialysis, including in-center hemodialysis, homo hemodialysis, daily hemodialysis, nocturnal hemodialysis.

In-center dialysis means that you need to go to dialysis center in hospital, which is usually done 3 days a week and 3 to 5 hours a day.

Home dialysis is done at home on the condition that you are trained well. It is usually done 3 days a week or every other day.

Daily home dialysis is similar with home dialysis, but it usually done 5 to 7 days a week at home and takes about 3 hours a day.

Nocturnal hemodialysis is done 3 to 7 nights a week at home and each session is done over night.

What are the hemodialysis facts?

- Hemodialysis machines are very expensive; the American Association of Kidney Patients report dialysis costs nearly $30,000 a year.

- Installing a machine at home can cost even more with nearly $2,000 in piping, tubing and installation costs.

- In a recent survey, more than 90% of nephrologists said they would choose a home therapy for themselves if faced with dialysis, with home hemodialysis as the preferred option.

Dos and donts of hemodialysis

- Increase protein intake decrease potassium, phosphate intake and limit fluids.

- Avoid morphine codeine; reduce doses of SSRIs and avoid vitamin A supplements.

- Monitor potassium levels

- Control BP and lipid levels

- Keep immunizations up to date, particularly in patients who may be candidates for transplantation

- Assess patient for anxiety

- Testing for renal osteodystrophy and follow-up if results abnormal.

- Smoking and alcohol cessation

- Maintenance of healthy weight

- Regular excise
