Continuous renal replacement therapy (CRRT) is a life-saving treatment for patients who are very critically ill and unstable with multi-organ damage, including renal failure and low blood pressure, acute kidney injury, or other forms of kidney failure. CRRT is a type of specialised dialysis that removes excess fluids and waste products from the blood in a continuous and gentle manner, similar to how the kidneys normally function.
CRRT can also help to correct electrolyte imbalances, acid-base disorders, and inflammation that may occur in patients with kidney failure. CRRT is performed in an intensive care unit (ICU), using a special machine that filters the blood and replaces the plasma with a suitable fluid. The procedure requires careful monitoring and adjustment by trained medical staff, as well as anticoagulation to prevent blood clotting. CRRT can improve the survival and recovery of patients with kidney failure, especially those who are not suitable for conventional dialysis.
A separate dialysis machine is dedicated to this procedure. Patients are monitored around the clock during the procedure, which is carried out continuously for a period of 24 to 48 hours.
