Solutes are removed from the blood by diffusion and convection. Excess plasma water is removed by ultrafiltration.Native arteriovenous (AV) fistulas are the preferred access for HD because of fewer complications and a longer survival rate. Venous catheters are plagued by complications such as infection and thrombosis and often deliver low blood flow rates.Adequacy of HD can be assessed by the Kt/V and urea reduction ratio (URR). The National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative minimum goal Kt/V is greater than 1.2 per treatment and the URR is greater than 65%.During HD, patients commonly experience hypotension and cramps. Other more serious complications include infection and thrombosis of the vascular access.Peritoneal dialysis (PD) involves the instillation of dialysate into the peritoneal cavity via a permanent peritoneal catheter. The peritoneal membrane lines the highly vascularized abdominal viscera and acts as the semipermeable membrane. Solutes are removed from the blood across the peritoneum via diffusion and ultrafiltration. Excess plasma water is removed via ultrafiltration created by osmotic pressure generated by various dextrose or icodextrin concentrations.Patients on PD are required to instill and drain, manually or via automated systems, several liters of fresh dialysate each day. The more exchanges completed each day results in greater solute removal.Peritonitis is a common complication of PD. Initial empiric therapy for peritonitis should include intraperitoneal antibiotics that are effective against both gram-positive and gram-negative organisms.Nasal carriage of Staphylococcus aureus is associated with an increased risk of catheter-related infections and peritonitis. Prophylaxis with intranasal mupirocin (twice a day for 5 days every month) or mupirocin (daily) at the exit site can effectively reduce S. aureus infections.
