Continuous renal replacement therapy (CRRT) is a type of dialysis used to treat acute kidney injury or chronic kidney disease. It is a slow, continuous process that removes excess fluid, toxins, and waste from the blood, and restores electrolyte and acid-base balance . Unlike traditional intermittent hemodialysis, which is typically performed for 3-4 hours per session, CRRT is performed continuously, 24 hours a day, often using a specialized machine called a hemodialyzer or dialyzer. The hemodialyzer or dialyzer removes excess fluid and waste from the blood and returns the clean blood to the patient's body .
CRRT is recommended for patients with impaired kidney function, also known as acute kidney injury (AKI). ICU patients undergo this treatment 24 hours a day .
