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].

The renal clearance of iohexol was evaluated as an alternative method for RRF assessment (iohexol-derived RRF) in hemodialysis patients. An intravenous bolus of iohexol (12 ml; 300 mg iodine/ml) was administered to 42 hemodialysis patients following routine HD. 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 hemodialysis. The established method based on urine collection and blood sampling is less suited for everyday clinical practice. between plasma clearance and renal clearance of iohexol.3 For dialysis-dependent patients with chronic kidney failure, the time at which the last blood sample is drawn should be delayed even further. We measured between-dialysis 2-sample plasma iohexol clearance for which the last sample was taken 44 hours after in- Iohexol transmembrane clearance during modeled continuous renal replacement therapy. Yardman-Frank JM, Mercier RC, Wong CS, Vilay AM. BACKGROUND/AIMS: Urea clearance during continuous renal replacement therapy (CRRT) is not representative of middle molecular weight solute clearances.

Iohexol clearance in hemodialysis

However, a late sample is not always feasible, for example, in patients treated with peritoneal dialysis (7 days per week) or frequent hemodialysis (4-7 days per week). Furthermore, relatively little is known about extrarenal CLiohexol in humans, including its source (presumably hepatic), variability, and dependence on serum iohexol concentrations. 1996-01-01 · The renal clearance of iohexol was evaluated as an alternative method for RRF assessment (iohexol-derived RRF) in hemodialysis patients. An intravenous bolus of iohexol (12 ml; 300 Residual renal function (RRF) may contribute significantly to the total dialysis prescription.

Conclusion The dialyzability of iosimenol was evaluated using a newly developed in vitro dialysis system, and iosimenol was readily cleared from blood with all four tested membranes.

Residual renal function (RRF) may contribute significantly to the total dialysis prescription. Conventional quantitation of RRF in hemodialysis (HD) patients is measured by urea clearance and requires a 24-hour urine collection which is often difficult to perform and inaccurate. The renal clearance of Use of iohexol to quantify hemodialysis delivered and residual renal function. This result agrees with data from anuric patients for whom extrarenal iohexol clearance was measured between 2 hemodialysis sessions.

The average deviation between Iohexol and (99m)Tc-DTPA clearance was 7.4 ml/min/1.73 m2. Allergic and nephrotoxic side effects were not observed. CONCLUSION: Iohexol clearance is a valid method for measuring GFR in patients at any stages of renal failure. Elimination rate and clearance of the contrast media were measured as indices of their dialyzability.

Total body clearance of iohexol (C mg iodine/ml) was administered to 42 hemodialysis patients following routine HD. A single blood sample was obtained approximately 44 hours later (pre-HD) to determine the plasma clearance of iohexol using x-ray fluorescence methods.
