- less responsibility
- days off
- proven effective long term
Disadvantages:
- tied to dialysis time
- access/line problems
- fluid/food restricted
Advantages and disadvantages of peritoneal dialysis
Advantages:
- continuously at home - independence
- less fluid/food restrictions
- easy to travel
- renal function may be better preserved initially
Disadvantages:
- frequent daily exchanges/overnight

Outline haemodialysis
- shunt (push through multiple veins + arteries together)
- anticoagulant added into blood
- blood is run through machine + filtered
- run through air trap to remove air
- added back to body
Outline peritoneal dialysis
- solution infused into peritoneal cavity through catheter
- solution contains sugar which draws out waste + extra fluid
- waste and fluid passes from blood vessels through peritoneum
- solution drained out
