Dialysis is a process for removing pathogenic substances from the blood to
achieve the purpose of treating disease. It includes hemodialysis,
hemofiltration, hemoperfusion, plasmapheresis, immune adsorption, etc. The
following is a briefly introduction on the different dialysis methods.
Hemodialysis: one of the longest and most widely used method. Due to the safe
and feasible character, it can be applied to most of the patients with renal
failure.
Hemofiltration: a dialysis method based on hemodialysis. Since it is more
close to the renal function, the effect is better than hemodialysis.
Plasmapheresis: is a removal treatment and return of (components of) blood
plasma from blood circulation.
Immune adsorption: the removal of antibody from antiserum by specific
antigen, with aggregation of the antigen-antibody complex followed by separation
of that complex by means of centrifugation or filtration.
Hemoperfusion: similar to immune adsorption, this technique is only
infrequently utilized as a medical process used to remove toxic substances from
a patient's blood.
Indications and contraindications
The indications for hemodialysis include:
①Acute renal failure;
②Acute drug or toxic poisoning;
③Chronic renal failure(Kidney Failure);
④Renal failure before transplant or the transplanted kidney has no
function;
⑤Other diseases (liver failure, schizophrenia, psoriasis, etc.).
Contraindications for hemodialysis include:
①Hypotension and shock;
②Severe hematosepsis;
③Severe myocardial dysfunction or coronary artery disease (CAD);
④3 days after big operations
⑤Hematencephalon, severe bleeding tendency and anemia;
⑥Mental disease;
⑦Malignant tumor.
Can you stop dialysis
Whether the dialysis can stop or not is depended on the patient's body
condition. Hemodialysis is commonly known as artificial kidney, but it only
replaces the non-functional kidney, ensures the operation of human metabolism.
It does not have the efficacy of rehabilitate the kidney. For the end stage of
the uremia, the renal function can only be replaced by hemodialysis.
The all above is a briefly introduction about dialysis, if you have anything
to consult, please contact with our online doctor, thank you.
