Pt-Iohexol-clearance, absolut NPU28293 Pt-Iohexol-clear

2013-06-15 2010-08-01 The calculation of 51 Cr‐EDTA clearance by method II (Cl II) was based on a close relation between 51 Cr‐EDTA clearance and the reciprocal apparent volume of distribution normalized with respect to body surface area. It was demonstrated that the two methods were closely related. To test the accuracy of the two methods, the results of Cl I and CI II, were compared to 51 ‐EDTA clearance calculated by means of a standard, multiple plasma sample method … Multiple sample methodThe plasma clearance of 51 Cr-EDTA for the entire group of cats ranged between 0.4 and 8.7 ml/min/kg when normalised for body weight (mean AE SD, 3.7 AE 2.5 ml/min/kg).The mean AE SD for the normal cats yielded to 2.4 AE 1.3 ml/min/kg. The mean clearance value for the hyperthyroid cats AE SD was 4.3 AE 1.9 ml/min/kg.

A method is described whereby the plasma clearance of 51 Cr‐EDTA is used to estimate the glomerular filtration rate (GFR) in conscious rats. EDTA clearance rates were calculated based on one and two exponential disappearance curves and compared in groups of animals studied under conditions of normal, high and low GFR. 1986-01-01 Total plasma clearance of 51Cr‐EDTA, Cl, is widely used as a measure of GFR. Commonly, only the final part of the plasma concentration curve is measured, and a one‐pool clearance (slope Reassessment of a classical single injection 51Cr‐EDTA clearance method for determination of … Determination of optimal sampling times for a two blood sample clearance method using 51 Cr-EDTA in cats Eva Vandermeulen, DVM , Carlos De Sadeleer, MD, PhD , Amy Piepsz, MD, PhD , Hamphrey R.

Van Hoek, DVM, PhD , Sylvie Daminet, DVM, PhD, DipACVIM, DipECVIM-CA , Guido Slegers, Dr Pharm, PhD , and Kathelijne Y. … Renal clearance of creatinine was significantly lower than renal clearance of iohexol (p = 0.0019) and 51Cr-EDTA (p = 0.0001). There were no significant differences between the renal clearances (Clren adv) of iohexol and 51Cr-EDTA or between their plasma clearances (ClAUC-3comp). 1998-05-01 2006-07-25 Iohexol and 51Cr-EDTA are comparable as GFR markers for multiple-point clearance measurements. The single-sample method for GFR >40 ml/min can be used with a high accuracy.

Measuring GFR: A Systematic Review. - Lunds universitet

GFR can be determined by measuring the rate of tracer disappearance from The precision of two different clearance methods as used for routine assessment of the glomerular filtration rate (GFR) was investigated in thirty-one children aged 0.6-14 years: total [51Cr]EDTA plasma clearance (E) determined by a simplified single injection method; and 24 h endogenous creatinine clearance (C). Determination of C twice only succeeded in twenty children because of problems in GFR measurement with iohexol and 51Cr-EDTA. A comparison of the two favoured GFR markers in Europe 1997-10-01 2009-01-01 From a large database of 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) renal clearance determinations using the two blood sample method, 598 patients, aged 1 week to 90 years, were selected. The results of the 51Cr-EDTA slope intercept clearance of the two blood sample method were used as reference. Methods: Two groups of patients with 51Cr-EDTA clearance (Cl) between 16 and 172 ml/min were studied. In Group I (n = 46), reference Cl was determined as a multiplasma sample, single-injection method (ClSM).

Cl was determined in 149 subjects (M/F/children: 71/46/32) from a complete plasma concentration curve followed for 4–5 h after injection of 51Cr‐EDTA (range of clearance: 8–183 mL/min/1.73 m2).

The calculation of 51Cr-EDTA clearance by method I (ClI) was based on a transformation of the biexponential time-activity curve into a monoexponential with identical area below the time-activity curve. The calculation of 51Cr-EDTA clearance by method II (ClII) was based on a close relation between 51Cr-EDTA clearance and the reciprocal apparent volume of distribution normalized with respect to body … BACKGROUND AND OBJECTIVES: 51Cr EDTA clearance (CL) from plasma is used to estimate glomerular filtration rate (GFR).
