Continuous renal replacement therapy (CRRT) is often used to support critically ill patients with acute kidney injury, especially hemodynamically unstable patients.

How long can a patient stay on CRRT?

In general, CRRT is typically used as a temporary treatment option for patients who are critically ill and require renal replacement therapy. The length of treatment can range from a few days to several weeks, depending on the underlying cause of renal failure and the patient's response to therapy.

CRRT: When It's Needed and How It Works

Q: When is renal replacement therapy needed?

CRRT may be needed in a variety of conditions, including: End-stage renal disease (ESRD) Acute kidney injury (AKI) Chronic kidney disease (CKD) Certain toxic ingestions or overdoses

Q: How do you know if CRRT is effective?

Once a person produces more than 500 millilitres to 1,000 millilitres of urine daily, doctors can test to see if the urine is filtering out toxins, a sign that the kidneys are working hard to recover.

Q: What are the basic principles of CRRT?

Whatever the RRT technique, the basic principle is the removal of unwanted solutes and water through a semi-permeable membrane. The water is removed by a process called ultrafiltration.

Frequently Asked Questions

What is continuous renal replacement therapy, and when is it commonly used?

Continuous renal replacement therapy (CRRT) is used for patients with acute kidney injury (AKI) or other forms of kidney dysfunction requiring specialized Renal Sciences care. CRRT is a slow and continuous process that removes excess fluids, electrolytes, and waste products from the blood, similar to dialysis. However, unlike dialysis, CRRT is performed continuously over 24 hours or longer, allowing for more gradual and gentle fluid and electrolyte balance corrections.
