Peritoneal Dialysis vs Hemodialysis - Advantages and Disadvantages 

Peritoneal Dialysis:

 • Access: Abdominal wall insertion of plastic catheter into the pertoneum. Limitations: swimming and bathing can be contraindicated. Previous abdominal surgery can be a contraindication: rarely, a patent

pleuro-peritoneal canal exists

 • Timing: Daily exchanges. either every 6 hours (CAPD). or attached to an overnight (continuous) cycling machine (8 hours) (CCPD): no non-dialysis days

 • Complications: Peritonitis (usually staphylococcal). Poorer exchange rates over time. Peritoneal sclerosis in the long term

Hemodialysis:

 • Access: Arteriovenous fistula, usually in the forearm

 • Timing: 5-7 hours every 2nd or 3rd day: in some circumstances, daily or overnight hemodialysis can be offered (e.g. pregnancy): some non-dialysis days

 • Complications: Bleeding from insertion sites. Fistula aneurysm formation. Recirculation or 'steal' phenomenon. Poor flow rates and technical difficulties. Fistula thrombosis or infection. Progressive neurological disease.
