Iohexol clearance, Pt- - NU-sjukvården
Iohexol 300 is recommended for cerebral arteriography at the following volumes: common carotid artery (6 mL to 12 mL), internal carotid artery (8 mL to 10 mL), external carotid artery (6 mL to 9 mL), and vertebral artery (6 mL to 10 mL). Excellent agreement has been demonstrated between 51Cr-EDTA-clearance and iohexol-clearance estimates (14, 15) (correlation co-efficients 0.92-0.95). Agreement with 99Tc-DTPA methods has not been well-demonstrated. Plasma iohexol clearance measurement is more practicable than urinary 2015-04-13 · Additionally, iohexol clearance has been successfully standardized for the assessment of renal function in dogs [8–11] compared with Tc 99m DTPA clearance and inulin clearance. This marker has been successfully evaluated in different animals [ 12 – 17 ]; however, there are no reports of its use in studies involving rats.

Comparison of studies reporting renal clearance measurements using iohexol versus The derived feline correction formula applied to slope-intercept plasma iohexol clearance accurately predicted multisample clearance in cats. Use of this technique offers an important advantage by reducing stress to cats associated with repeated blood sample collection and decreasing the costs of an … The present study examined the agreement between single and multiple sample plasma clearance of iohexol, a non-ionic contrast agent, in renal failure. Sixty-five patients with varying degree of renal insufficiency received 10 ml iohexol (300 mg I/ml) i.v. and plasma samples were collected four times during the following 3-24 h. 2020-02-01 · Iohexol serum clearance has become a new gold standard, but it is challenging when GFR is low and 24-hour sampling is required for accurate results. The primary aim of this study was to develop an iohexol pharmacokinetic population model for accurate determination of individual GFR using limited sampling for up to 5 hours also when renal function is <40 ml/min. Iohexol 300 at a concentration of 300 mgI/mL is indicated in adults for use in cerebral arteriography.

Studying the difference between plasma and urinary clearances in healthy subjects, the extra-renal clearance of iohexol was between 0 and 6 mL/min/1.73 m 2 [ 22, 26, 30, 36] or 5% [ 25 ]. Iohexol is a safe, nonionic, low osmolar contrast agent (MW 821 Da). It is eliminated exclusively by the kidneys, where it is filtered but not secreted, metabolized, or reabsorbed. It has less than 2% binding to protein. of iohexol clearance.

Clearance angis i milliliter per minutt, og brukes for å bestemme den glomerulær filtrasjonsraten (GFR), som er et mål på nyrefunksjonen.Ioheksol er et kontrastmiddel som vanligvis brukes ved røntgenundersøkelse. Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research projects. However, lack of standardization for iohexol assays and the use of different protocols such as single- and multiple-sample methods could potentially hamper comparisons across studies. Iohexol is an X-ray contrast medium containing iohexol in various concentrations, from 140 to 350 milligrams of iodine per milliliter.
Therefore, we compared the renal and plasma clearances of iohexol and chromium-51
clearance of iohexol. Methods: A total of 46 healthy volunteers and 124 chronic kidney disease (CKD) patients with varying degrees of renal dysfunction received 5 ml iohexol (300 mgI/ml) i.v. and pla sma samples were drawn at 2-, 3- and 4-h post-injection. Plasma-iodine concentrations were detected by high-performance liquid chromatography (HPLC). Iohexol plasma clearance as a measure of glomerular filtration was determined in 31 dogs and 19 cats after an intravenous (i.v.) bolus injection. All animals were healthy and privately owned.

However, lack of standardization for iohexol assays and the use of different protocols such as single- and multiple-sample methods could potentially hamper comparisons across studies. Iohexol is an X-ray contrast medium containing iohexol in various concentrations, from 140 to 350 milligrams of iodine per milliliter. NCI Thesaurus (NCIt) Iohexol is a benzenedicarboxamide compound having N-(2,3-dihydroxypropyl)carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and an N-(2,3-dihydroxypropyl)acetamido group at the 5-position.
Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality. Iohexol clearance is considered a reliable reference method for the determination of GFR. The aim of this study is to, for the first time, evaluate the diagnostic accuracy of plasma cystatin C compared with iohexol clearance in cardiac surgery. Platinum clearance had a significant linear relationship to GFR (99mTc-DTPA) (CL (PT) = 2.5 x GFR (99mTc-DTPA)) and to GFR (Iohexol) (CL (PT) = [1.3 x GFR (Iohexol)] + 1.4). Iohexol Clearance in Critically Ill Patients With Augmented Renal Creatinine Clearance (GFR-ARC) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. The GFR of 96 children with different stages of chronic kidney disease (CKD) (median age 9.2 years, range 3 months to 17.5 years) was determined using the iohexol plasma clearance, with blood sampling at seven time points within 5 h (GFR7p) as the reference method. Median GFR7p was 65.9 (range 6.3–153) mL/min/1.73 m2.
