Continuous Renal Replacement Therapy (CRRT)

A continuous dialysis treatment used in critically ill patients with acute kidney failure.

What is CRRT?

CRRT is a type of dialysis performed 24 hours a day in an intensive care setting. It gently removes waste products, toxins, and excess fluids from the blood when the kidneys are not functioning properly. This method is less stressful on the body than traditional dialysis, making it suitable for unstable or critically ill patients.

This treatment helps to:

Remove waste and toxins from the blood

Control fluid balance in patients with severe illness

Correct electrolyte and acid-base imbalances

Support kidney function until recovery or transition to standard dialysis

Improve stability in patients with sepsis or multiple organ failure

What to expect during treatment?

CRRT is performed in the hospital, usually in the intensive care unit (ICU).

Continuous 24-hour therapy with close monitoring

Gentle and gradual fluid removal compared to standard dialysis

Connection to a dialysis machine through a central venous catheter

Possible mild discomfort at the catheter site

Daily adjustments based on blood test results

Why is it performed?

For critically ill patients with acute kidney injury
To manage fluid overload not controlled by medication
To correct life-threatening electrolyte imbalances
To support patients with sepsis or multi-organ failure
As a bridge to kidney recovery or chronic dialysis

Risks and Considerations

Risk of infection at the catheter site
Low blood pressure due to fluid removal
Possible bleeding complications from anticoagulants used during therapy
Electrolyte imbalances if not closely monitored
Requires specialized hospital care and monitoring

Early detection is important for managing the condition and preventing further complications.

FAQs

Is CRRT the same as regular dialysis?

No. Unlike traditional dialysis, which is intermittent, CRRT works slowly and continuously, making it safer for unstable patients.

How long does CRRT last?

It can continue for several days or weeks, depending on the patient’s condition and kidney recovery.

Can patients eat or drink during CRRT?

Yes, if medically stable, but diet is carefully monitored to support kidney function.

Is CRRT painful?

No, the procedure itself is not painful, though mild discomfort may occur at the catheter site.

When should family contact the doctor or nurse?

If they notice swelling, bleeding at the catheter site, sudden changes in the patient’s alertness, or worsening instability.
