Dialysis

Alternative Names:
Artificial kidneys; Hemodialysis; Peritoneal dialysis; Renal replacement therapy;

What the risks are:

The immediate risks include:

  • Hypotension (low blood pressure)
  • Infection
  • Electrolyte imbalance
  • Bleeding from the access site
  • Nausea and vomiting
  • Cramps
  • Dialyzer reaction
  • Air embolism
  • Cardiac ischemia or arrhythmia (irrregular heart beats)

Long-term risks include:

  • Dialysis-associated amyloidosis
  • Dialysis dementia (uncommon now that aluminium levels are closely monitored)
  • Cardiovascular disease
  • Autonomic Neuropathy
  • Blood loss leading to iron deficiency (requiring regular iron replacement)


Special considerations:

Take the following precautions if you using an AVF or AVG:

  • When you sleep, avoid placing pressure on an arm with the access.
  • Do not allow anyone to take a blood pressure reading on an arm with the access.
  • Observe the access site after dialysis, watching for swelling, infection, or bleeding.
  • Do not wear tight clothing around the access site.
  • Routinely check the access site for the "thrill", indicating that the AV site is still functioning. (If the thrill disappears, call your health care provider immediately.)
  • Do not use creams or lotions over the access site.
If you have an external access, take additional precautions:
  • Avoid physical activity that might dislodge the access, which could result in excessive bleeding and air entering the circulatory system. (If this happens, call 911 and get immediate medical attention.)
  • If the color in the tubes changes color and becomes a dark red, call your health care provider immediately. (The blood may be clotting.)
  • Call your health care provider immediately if your have a fever or other sign of infection.
