When is
Dialysis Used?
Dialysis is
primarily used as
renal replacement therapy
to provide an artificial replacement for lost
kidney
function due to
renal failure.
Dialysis may be used for very sick patients who have suddenly but temporarily,
lost their kidney function (acute
renal failure) or for quite stable patients who have permanently lost
their kidney function (stage
5 chronic kidney disease). For patients with stage 5 or End-Stage
Kidney Disease (ESKD), the decline in kidney function occurs over a period of
months to years until a level is reached at which treatment is needed for
survival. The best available treatment for ESKD is a
kidney transplant;
however, some patients are not good candidates for a transplant due to medical
or other reasons, some cannot receive a transplant because of the short supply
of donor kidneys, and others simply decide that a transplant is not the best
option for them. As a result, most patients with ESKD must rely on dialysis to
replace the water and waste removal functions of the healthy kidneys; though
dialysis is an imperfect treatment to replace kidney function because it does
not correct the
endocrine
functions of the kidney.
Dialysis at Apollo Hospitals Dhaka
There are two
primary types of dialysis,
hemodialysis
and
peritoneal dialysis.
Apollo Hospitals Dhaka at present with 10 single
hemodialysis machines is providing support to the patients on
out-patient and in-patient basis. Among others there are portable machines used
for dialysis of patients at their bed side and also dedicated machines for
patients who have identified infectious diseases like Hepatitis B, Hepatitis C
and others. In Apollo Dialysis Unit the dialyser machines are disinfected with
sodium chloride and auto rinse cleaning system after completion of each dialysis
cycle. For patients who have very low diastolic blood pressure even less than
60mm Hg, Continued Renal Replacement Therapy (CRRT)
is also practiced at their bed side.
In
Apollo Dialysis Unit, before the
procedure, patients are screened for infectious disease like Hepatitis B,
Hepatitis C or HIV. If diagnosed positive then dialysis machines specific for
infection positive patients are used.
How
does Dialysis work?
Hemodialysis
removes wastes and water by circulating blood outside the body through an
external filter, called a dialyzer that contains a semipermeable
membrane. The blood flows in one direction and the dialysate (special
dialysis fluid) flows in the opposite; the counter-current flow of the blood and
dialysate helps to remove more urea and creatinine from the blood. The
undesirably high blood concentrations of
potassium,
phosphorus,
and urea) are constantly replaced by dialysis solution having levels of
minerals like potassium and calcium that similar to the natural concentration of
healthy blood.
In
peritoneal dialysis,
wastes and water are removed from the blood inside the body using the peritoneal
membrane as a natural semipermeable membrane into a special dialysis solution,
called dialysate, in the abdominal cavity which has a composition similar to the
fluid portion of blood.
Peritoneal
dialysis works slower than hemodialysis, but because it is carried out for a
longer period of time the net effect in terms of removal of waste products and
of salt and water are similar to hemodialysis. Peritoneal dialysis can be
carried out at home by the patient. Although support is helpful, it is not
essential. It does free patients from the routine of having to go to a dialysis
clinic on a fixed schedule multiple times per week, and it can be done while
traveling with a minimum of specialized equipment.
Apollo Dialysis Unit
Apollo
Dialysis Unit
has dedicated skilled nurses and technicians and is
open from 7am to 11pm every day of the
week. With high level of experience and skill, the medical and nursing staff
keeps the patients under dialysis under close observation and monitoring under
direct supervision and follow-up of Consultant
Nephrology.
