CRRT
Also written as: CRRT — Continuous Renal Replacement Therapy
A slow, continuous form of dialysis used for critically ill patients with acute kidney injury.
Full Definition
Continuous Renal Replacement Therapy is a 24-hour dialysis technique that provides gradual removal of fluid and solutes in hemodynamically unstable patients. In pediatric critical care, CRRT is preferred over intermittent hemodialysis for patients with cardiovascular instability, brain injury, or severe fluid overload. Common modalities include continuous venovenous hemofiltration (CVVH), continuous venovenous hemodialysis (CVVHD), and continuous venovenous hemodiafiltration (CVVHDF). The therapy requires specialized nursing care and anticoagulation management.
Usage
Usage note: Specify the exact modality (CVVH, CVVHD, CVVHDF) when known.
