WebIntroduction. Renal clearance is most commonly a feature of polar, low LogD7.4 (<~1) compounds due to their low plasma protein binding, lack of passive permeability (and inability to facilitate re-absorption in the distal tubule), and the high expression in the kidney of a number of transporter proteins (e.g. OATs and OCTs). WebNov 3, 2024 · This method of prescribing a lower hemodialysis dose depending on the clearance provided by residual kidney function is called incremental hemodialysis [ 4 ]. The amount of prescribed hemodialysis can be decreased by reducing the hemodialysis time (for example, by time per session or by number of sessions) or by altering operating …

K (clearance) multiplied by t (time) is a volume (since mL/min × min = mL, or L/h × h = L), and (K × t) can be thought of as the mL or L of fluid (blood in this case) cleared of urea (or any other solute) during the course of a single treatment. V also is a volume, expressed in mL or L. So the ratio of K × t / V is a so-called "dimensionless ratio" and can be thought of as a multiple of the volume of plasma cleared of urea divided by the distribution volume of urea. When Kt/V = 1.0, … WebIn the equation, ln stands for the natural logarithm, C 0 is the initial urea concentration, and C t is the ending urea concentration.
