hemodialysis Vs peritoneal dialysis
RENAL REPLACEMENT THERAPY
Haemodialysis:
blood from the patient is pumped through an array of semipermeable membranes (the dialyser, often called an 'artificial kidney') which bring the blood into close contact with dialysate, flowing countercurrent to the blood.
Peritoneal dialysis:
Peritoneal dialysis utilizes the peritoneal membrane as a semipermeable membrane, avoiding the need for extracorporeal circulation of blood. This is a very simple, low-technology treatment compared to haemodialysis.
hemodialysis requires patient to stick to a schedule and go to a facility to have the treatment while peritoneal dialsis can be done at home, at the time that's best for patient.
hemodialysis give superior electrolyte control but require more time travilling.
peroteneal dialysis have greater risk of infection and the process need to be performed 3 times a day.
