dialysis Flashcards
peritoneal dialysis
type of dialysis which uses the peritoneum in a person’s abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure.

how pd works
g peritoneal dialysis, a cleansing fluid (dialysate) is circulated through a tube (catheter) inside part of your abdominal cavity (peritoneal cavity). The dialysate absorbs waste products from blood vessels in your abdominal lining (peritoneum) and then is drawn back out of your body and discarded.
two ways for peritoneal dialysis
continuous pd
automated pd
continuous pd
(CAPD) Constant dialyis change daily
done easily flexible, works with gravity, dialysate up, drain bag low
automated pd
overnight machine does the work 8 to 10 hour
connect to the machine
pd pros
continous dialysis, fluid removal, gently and easily controlled, reduces stress, eat more, continue daily activity, fewer meds, can trace,
pd is not appropriate for some
obeses, multiple abdominal surgeries (difficult and impossible)
pd can be as effective as
haemodialysis
haemodialysis
seperation of blood, taken blood, taken blood from access and filter line a kidney effectively cleaning the blood
access of haemodialysis
atrioventricular fistula
atrioventricular graft
central venous cather
AVF
artery is surgically joned with vein
non dominant forearm
least complications- utilised own patient tissue
AVG
a synthetic tube is transplanted into the wrist connecting the artery and vein
more complications, clotting
