title: Pre-vs. post-dilutional hemofiltration.
abstract: The advantages and disadvantages of pre- and postdilution in hemofiltration are discussed, and formulae are derived for sieving coefficient, fractional clearance, and hemofiltration clearance. On the basis of these formulae the two methods are compared, and it is concluded that the present state of membranes is such that the postdilution method is more convenient and cheaper.
