Golper, 1 2 3 1 University of Arkansas for Medical Sciences, Little Rock, Arkansas, and Oregon Health Sciences University, Portland, Oregon, USA; and Lister Hospital, Stevenage, England, United Kingdom To measure the accuracy of iohexol clearance using a clinically simple 2-sample single injection technique, a comparison was made in 30 patients with classical continuous infusion techniques for Iohexol clearance has been shown to be a marker of the glomerular filtration rate in patients with normal and impaired renal function. Investigators from Minneapolis used the iohexol clearance to estimate RRF in hemodialysis patients and compared iohexol clearance to urea clearance. Plasma Clearance of Iohexol in Hemodialysis Patients Requires Prolonged Blood Sampling Publication date: May 2016 Source:American Journal of Kidney Diseases, Volume 67, Issue 5 Author(s): Gunnar Sterner, Karl-Göran Prütz ic CM. Values of clearance and molecular weight correlated well. Conclusion: The molecular weight of a contrast medium is the main factor that in- fluences the efficiency of CM removal by hemodialysis.

Renal clearance of iohexol (C Io), a non-radioactive non-ionic radiocontrast Key words: Kt/V, hemodialysis delivered, urea kinetics, urea reduction ratio, end-stage renal disease, mortality and dialysis, clearance, glomerular ﬁltration rate. Received for publication November 11, 1997 The purpose of this study was to determine whether iohexol (Io; molecular wt = 821) could be used instead of urea and provide better information as well as middle molecule clearance data. METHODS: Ten hemodialysis (HD) patients were evaluated. The iohexol mass removed by dialysis and the residual renal function (if any) equals the difference of the two estimates of body iohexol, see eq.4.

RESULTS: After 4 hours of hemodialysis, 78.4+/-6.5% of iohexol and 72.4+/-6.0% ioxaglate were eliminated. Clearance of iohexol was higher than that of ioxaglate at all sampling times.

An intravenous bolus of iohexol (12 ml; 300 mg iodine/ml) was administered to 42 hemodialysis patients following routine HD. extrarenal iohexol clearance was measured between 2 hemodial-ysis sessions.3,4 Thus, we believe that properly performed plasma iohexol clearance using long sampling time is a suitable technique for estimating residual kidney function in patients receiving hemodi-alysis. The established method based on urine collection and blood Plasma clearance of iohexol in hemodialysis patients requires prolonged blood sampling. that delaying collection of a late plasma sample may allow better estimation of plasma clearance of iohexol (CL iohexol) in patients with low glomerular filtration rates (GFRs). Iohexol is a non-ionic, low-osmolar, X-ray contrast medium with a molecular weight of 821 Daltons and it is mainly eliminated from plasma in its intact form by glomerular filtration (extrarenal clearance ≈2 ml/min) and it is often stated to be effectively removed by HD [7, 8]. The total clearance of iohexol was 70.4 +/- 24.6 ml/min and was very close to dialyzer clearance, as estimated from blood flow and extraction ratio. The plasma iohexol level after dialysis was related to the dose administered, iohexol clearance, and the patients' body weight.

All clearance measurements are reported in mL/min/1.73 m 2, and median [IQR] values were as follows: 24-hour plasma CL iohexol, 7.1 [5.3-9.4]; 4-hour plasma CL iohexol, 12.7 [7.8-18.0]; 24-hour urinary CL iohexol, 2.3 [0.5-4.3]; and 24-hour urinary CL urea,cr, 3.2 [1.6-5.4]. Iohexol clearance determinations are now per-formed at numerous hospitals in Sweden. A national quality assurance program, now including 20 different laboratories, was initiated in 1996.
