Since then, we have used the method extensively in experimen-tal medicine, and since 1988 it is the standard method for GFR measurements at our hospital. Iohexol clearance is now performed by at least 30 På förmiddagen ges en injektion av Iohexol via en venflon. Ett eller flera blodprov tas efter 3–5 timmar, men vid kraftigt sänkt njurfunktion (förväntat värde <20ml/min tas provet dagen efter. Tidsåtgång 4–5 timmar. Vid provtagning dagen efter, tidsåtgång: dag 1 ca 30 min, dag 2 ca 15 min.

Iohexol is very stable in serum, but we would recommend that any samples sent from outside the UK are shipped chilled or frozen to allow for the longer delivery time.

(2011) Glomerular filtration rate estimation by use of a correction formula for slope-intercept plasma iohexol clearance in cats. Urinary inulin clearance is considered the gold standard of glomerular filtration rate (GFR) measurement but plasma clearance of less expensive and more accessible tracers is more commonly performed. Many plasma sampling protocols exist but little is known about their accuracy. Here, the study objectives were to compare plasma iohexol and 99mTc-DTPA GFR with varying sampling strategies to the Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus californianus), without evidence of renal dysfunction, to determine if the one-compartment model and the sample protocol used in dogs and cats could be applied to this species. Nonlinearity between samples in 75% (6/8) of sea lions voided those results.

There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each.

In conclusion, plasma clearance of iohexol may well be the best candidate for a common GFR determination method.

23 A single dose of iohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg intravenously through an IV catheter. Abstract: Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus californianus), without evidence of renal dysfunction, to determine if the one-compartment 2018-08-28 · Iohexol plasma clearance is the most convenient method for measuring GFR in almost all clinical settings. However, in particular situations, where the extracellular volume is increased (ascites, oedema, in intensive care units) the evaluation of urinary clearance may be considered a more reliable procedure ( 21 ). Iohexolclearance ger ett tillförlitligt mått på njurarnas glomerulära filtrationsförmåga (GFR). Används när en precis skattning av GFR är önskvärd såsom inför njurtransplantion, vid dosering av vissa läkemedel eller njurmedicinska frågeställningar. 2.2 | Iohexol clearance protocol A standard protocol was used for performing the iohexol clearance tests via a limited sampling technique.23 Asingledoseofiohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg intrave-nously through an IV catheter.
