Peritoneal Dialysis | NEJM

• Fluid removed via convection using oncotic pressure (eg, dextrose). ↑ concentrations and dwell times removes more fluid (less as glc equilibrates).

• PD fluid: dextrose (1.5%, 2.5%, or 4.25%), buffer (lactate), Na+, Ca2+, Mg2+

• Infuse 10 min, dwell 90 min–5.5 h, drain 20 min; exchanges done manually or using cycler at night (automated or cont. ambulatory peritoneal dialysis APD, CAPD)

• types of peritoneal dialysis.

• Complications of Peritoneal Dialysis.

• Hyperglycemia: exacerbated by inflammation, long dwell times, and higher [glucose]

• Benefits: lower cost, independence, preservation of residual kidney function. No Δ mortality vs. HD (AJKD 2018;71:344).
