CRRT

Use of a filtration or dialysate bath device to remove fluid and small waste product molecules from the blood of patients with acute renal failure who are unable to tolerate hemodialysis.

Removal of water occurs as the result of diffusion, convection, and ultrafiltration. There are four types of CRRT. In all types, blood is removed continuously for 24 hr and passed through a chamber containing a semipermeable filter. Excess fluid is removed slowly and, as a result, there is decreased risk of hemodynamic instability when compared to hemodialysis. In arteriovenous systems, blood pressure provides the force by which blood moves through the filtration system. In venovenous systems, pumps propel the blood. Anticoagulants are added to reduce clotting stimulated by blood coming in contact with a foreign surface.

In continuous arteriovenous hemofiltration (CAVH) and continuous venovenous hemofiltration (CVVH), a catheter placed in a peripheral artery carries blood at a rate of 300 to 800 ml/hr through a chamber containing a semipermeable membrane. Excess water and solutes move across the membrane and out of the blood, which is then returned to the venous system.

In continuous arteriovenous hemodiafiltration (CAVHDF) and continuous venovenous hemodiafiltration (CVVHDF), the chamber through which blood passes contains a dialysate solution in addition to a filtration membrane. Changing the concentration of the solution increases the amount of waste products and water that can be removed from the blood as it passes through the device.
