WebMiddle-molecule clearance in postdilution CVVH (Qb = 200 ml/min; Qeffluent = 33 ml/min) was compared with that in CVVHD (Qb = 200 ml/min; Qd = 33 ml/min) for each dialyser. For each experiment, a fresh dialyser was used and allowed to equilibrate for 5 minutes before samples (blood pre- and postfilter; effluent) were collected. n = 3 samples ... WebThe sieving coefficient is between 0.87 and 1.0 and is not different between CVVH and CVVHD [72, 73]. Citrate removal with CRRT also depends on citrate concentration in the filter and filtration fraction; high fractions are associated with relatively higher citrate clearance and a lower buffer supply to the patient.
