CRRT
Pronunciation: see-are-are-tee
Also written as: CRRT — Continuous Renal Replacement Therapy
A form of dialysis that operates continuously over 24 hours, used for critically ill patients with acute kidney injury.
Full Definition
Continuous Renal Replacement Therapy (CRRT) is the preferred modality of renal replacement therapy in hemodynamically unstable critically ill surgical patients with acute kidney injury. Unlike intermittent hemodialysis, CRRT provides slow, continuous removal of fluid and solutes over 24 hours, minimizing hemodynamic stress and allowing for precise fluid balance management. CRRT modalities include continuous venovenous hemofiltration (CVVH), continuous venovenous hemodialysis (CVVHD), and continuous venovenous hemodiafiltration (CVVHDF). The therapy requires anticoagulation, careful monitoring of fluid balance, electrolytes, and filter function. CRRT is particularly valuable in surgical critical care for patients with multi-organ failure, severe fluid overload, or those requiring large volume medication infusions.
Usage
Usage note: Specify the CRRT modality (CVVH, CVVHD, CVVHDF) when relevant for clarity.
