continuous renal replacement therapy

Full Definition

Continuous renal replacement therapy provides gentle, around-the-clock removal of fluid and solutes in hemodynamically unstable patients who cannot tolerate intermittent hemodialysis. This modality is preferred in surgical ICU patients with acute kidney injury, severe fluid overload, or multi-organ failure. CRRT requires continuous anticoagulation and specialized nursing care, making it resource-intensive but safer for unstable patients.

Usage

Usage note: Often abbreviated as CRRT; includes subtypes CVVH, CVVHD, and CVVHDF.
