Continuous Renal Replacement Therapy (CRRT) is a 24-hour non-stop dialysis therapy used to support patients with renal (kidney) failure.
CRRT gently filters and cleans your child’s blood. Your child will need a special intravenous (IV) catheter in one of his or her large veins (usually in the neck or groin) for this treatment. The blood is removed from the body through the IV and sent through the CRRT machine. The blood is pumped through the filter, which cleans it and returns it to the body.
CRRT is needed when the kidneys are no longer able to remove enough waste and water from the blood. In this case, your child may need CRRT until the kidneys begin to work again. CRRT works like the kidneys to remove harmful waste and fluid. This helps keep the right balance of chemicals and electrolytes, like potassium and sodium, in your child’s blood. CRRT does the work of the kidneys while your child’s kidneys are trying to heal and get better.
