End

A little history . . . .• The first dialysis machine was made by Willem

Johan Kolff.• The first machines, made during World War II,

used everyday materials such as sausage skins, orange juice cans, and washing machines.

Kolff• Kolff was in danger as he was developing the

dialysis machine.• The first dialysis machines were not as effective

as was hoped. None of Kolff’s first fifteen patients lived, but their lives were extended by several days which gave him hope.

• In 1945, he successfully treated a patient.• Kolff donated his five dialysis machines to hospitals around the world after the war.

Dialysis today• Dialysis machines continued to improve.• Dr. Belding Scribner developed a method that

allowed dialysis machines to also help people that have chronic end stage renal disease. His device, the Scribner Shunt was the first step to today’s methods.

• Today patients may go to a dialysis center or perform dialysis at home.

o Their overall kidney function is so poor that it threatens health and survival.

• People waiting for a kidney transplant.

Statistics • One in ten American adults have some level of

CKD.• Approximately 25% of people 65 and over have

CKD.• Approximately 0.5 % of people 20 – 64 have CKD.
