Dialysis and kidney replacement

10 articles

Continuous ambulatory peritoneal dialysis

Continuous ambulatory peritoneal dialysis (CAPD) is a home dialysis for kidney failure in which the peritoneal membrane filters waste as patients manually exchange fluid several times daily, without a machine.

Continuous kidney replacement therapy

Continuous kidney replacement therapy (CKRT, historically CRRT) is blood purification run for 24 hours or longer in critically ill patients with acute kidney injury, removing fluid and solutes slowly and continuously.

Continuous renal replacement therapy

Continuous renal replacement therapy (CRRT), or continuous RRT, is a set of dialysis-like filtration techniques run for hours to days in critically ill ICU patients with acute kidney injury.

Dialysis

Dialysis is a medical procedure that removes waste products and excess water from the blood when the kidneys fail, mainly by hemodialysis or peritoneal dialysis.

Hemodiafiltration

Hemodiafiltration is a kidney-failure blood-purification treatment combining the diffusive solute removal of hemodialysis with the convective removal of hemofiltration, clearing middle molecules and lowering mortality in randomized trials.

High-flux dialysis

High-flux dialysis is a form of hemodialysis that uses dialyzer membranes with high water permeability and larger pores, allowing removal of middle-molecular-weight solutes such as beta-2-microglobulin beyond conventional low-flux clearance.

Home hemodialysis

Home hemodialysis is a renal replacement therapy in which a kidney failure patient performs dialysis at home on flexible schedules of two to seven sessions weekly.

Hybrid Renal Replacement Therapy

Hybrid renal replacement therapy (SLED, PIRRT, extended daily dialysis) combines CRRT-like slow solute and fluid removal with intermittent hemodialysis equipment; trials show mortality and hemodynamic outcomes comparable to CRRT at lower cost.

Icodextrin

Icodextrin (Extraneal) is a starch-derived glucose polymer, average MW 16,000 D, used as a 7.5% colloid-osmotic agent for long-dwell peritoneal dialysis exchanges, first registered 1997, with maltose-based glucose meter interference as its key warning.

Intermittent renal replacement therapy

Intermittent renal replacement therapy (IRRT) is dialysis-based kidney support for acute kidney injury in critically ill patients, delivered in sessions of a few hours, typically three per week, until kidney function recovers.
