- A substitute for kidney function in cases of very severe renal
- Removes waste products, free water, and acidity from the blood.
- Solutes and water are removed from the patient’s blood by
diffusion across a semipermeable membrane
- Heparin is usually used as an anticoagulant
- Complications can include: hypotension, fatigue, muscle cramps,
nausea, headache, infection, amyloidosis, neuropathy, and complications
due to heparin. In rare cases, anaphylaxis can occur with the
first episode of hemodialysis.
Other renal replacement therapies:
- Hemofiltration-Removes solutes by convection by forcing the
patient’s blood against a
semipermeable membrane at greater pressure than the other side, driving
flow of solutes and water.
- Hemodiafiltration-Combines approaches of hemodialysis and
- Acetate-free biofiltration-A variation of hemodiafiltration
that adds a continuous bicarbonate infusion back to the patient.
