  1. aDuring continuous veno-venous hemodiafiltration (CVVHDF) modality, prescribed clearance was delivered with even hemofiltration and hemodialysis flow rates. Where errors are given, results are means ± SD; ranges follow a semicolon. CVVH, continuous veno-venous hemofiltration; CVVHD, continuous veno-venous hemodialysis; KCALC, calculator-estimated urea clearance; KDEL, delivered clearance evaluated from urea concentrations on simultaneous blood and effluent samples; T0, at therapy start; T18, after 18 to 24 hours of uninterrupted therapy.
