Hemodialysis
Purpose
Hemodialysis is primarily used for patients with end-stage renal disease (ESRD) or acute kidney injury (AKI) to remove toxins and excess fluids from the bloodstream.
Procedure
During hemodialysis, blood is circulated outside the body through a machine called a dialyzer or hemodialyzer. This machine acts as an artificial kidney, filtering the blood and removing waste products and excess fluids. The cleaned blood is then returned to the body.
Access
Access to the bloodstream for hemodialysis is usually achieved through a vascular access point, which can be a catheter placed in a large vein, or a surgically created arteriovenous fistula or graft.
Frequency
Hemodialysis is typically performed several times a week, with each session lasting a few hours. The frequency and duration of sessions depend on the patient's overall health and the recommendations of their healthcare team.
Hemodialysis is a life-sustaining treatment for those with kidney failure, although it is only one part of managing the complex health needs of these patients.
