The replacement fluid may either be added to the circuit before the haemofilter (pre-dilution) or mixed with the blood in the venous drip chamber (post-dilution). Pre-dilution may reduce the incidence of filter clotting and hence anticoagulation requirements, but reduces clearance of solute; therefore, post-dilution is more commonly used.
