kidney dialysis Flashcards
what are the two types of dialysis
haemodialysis
and peritoneal dialysis
what happens in haemodialysis
blood from patients body enters the dialyzer
through semi permeable membrane waste products like urea, creatinine and excess potassium, excess fluids can go through
what happens in peritoneal dialysis
fresh dialysate enters the peritoneal cavity
in patients body for some time
excess waste products leave patients body
used dialysate leaves patient via catheter
where can haemodialysis take place
generally requires dialysis centre visits, can also be performed at home
how often is haemodialysis needed
3-4.5 hrs of treatment 3 times per week. (allows for 4 treatment free days per week)
cons of haemolysis
strict dietary constraints and salt/water restrictions
needs access - ideally an atriovenous fistula (requires operation under local anaethetic)
/ tunelled central venous line (latter carries risk of bacteraemia if become infected
where can peritoneal dialysis take place
performed at home, generally overnight
- saves journey time and travel requirement
how often does peritoneal dialysis take place
normally 7 days a week but can often have weekend off if needed
what are some adv of peritoneal dialysis
lesser constraints for food and water intake
can travel easily - machine packs into a wheelie suitcase and fluids delivered by companies internationally
day time changes can be done anywhere
disadv of peritoneal dialysis
chance of infections due to catheter / peritonitis

post transplant surgery recommendations
avoids nsaids, live vaccines, alcohol, smoking, raw eggs, raw meat, undercooked fish, unpast cheese, food items that can interact with tacrolimus
