Creatinine clearance exceeds GFR due to … flight ipad

"WebRenal Clearance. The concept of renal clearance is a very useful diagnostic tool in medicine. Clearance is a measurement that compares the rate that a substance is filtered back into the bloodstream with the rate at which the kidneys excrete the substance in the urine. The units for renal clearance are milliliters of plasma per minute. " - Dialysis clearance equation

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, … WebHemodialysis Not recommended Not recommended CRRT Not recommended Not recommended Monitoring: Initial Monitoring • Single level drawn 8 – 12 hours after the first dose. • Use nomogram to confirm/modify dosage interval. • Only applicable for 5 mg/kg – plotting doses lower or higher than 7 mg/kg may under or overestimate clearance)
