What Is Cvvhdf

Continuous veno-venous hemodiafiltration (CVVHDF) uses replacement fluid and dialysate. CVVHDF combines the benefits of diffusion and convection for solute removal. Top of page. Anticoagulation is needed to reduce the clotting of blood in the blood tubing set and filter.

Whats the difference between Cvvh and Cvvhdf?

CVVH uses convective clearance to remove toxins and solutes from the patients circulation, while CVVHD relies on diffusive clearance to remove these same toxins/solutes.

Is Cvvhdf better than Cvvh?

Mean survival time was longer in CVVHDF group with oliguric/anuric patients than in CVVH group. CVVH, and not classic risk factors, was associated with higher overall mortality in oliguric/anuric patients. In the linear regression model, hourly urine output was the strongest and positive predictor of longer survival.
