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. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3 mL) were collected from the orbital sinus at different points after injection.

We did Plasma clearance measurement is the protocol of choice as it combines a reliable GFR determination with convenience for the patient.

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.

In recent years, iohexol has been used as a filtration marker. The substance can be measured in plasma, serum and urine using high-performance liquid chromatography. So far, good agreement has been shown for GFR determined by the classic inulin clearance and by the iohexol plasma clearance.

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. make plasma iohexol clearance a reasonable option for both clinical trials and epidemiologic studies. However, standardization of iohexol assays is lacking, and different sampling protocols may lead to difﬁculties comparing results across studies.

Single-sample protocols Iohexol total clearance was identical to 51Cr-EDTA, whereas urinary clearance of iohexol was slightly higher. Finally, they showed that iohexol was distributed within the extracellular volume [22].

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.

This marker has been successfully evaluated in different animals [ 12 – 17 ]; however, there are no reports of its use in studies involving rats. 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. An additional two anesthetized sea lions were OMNIPAQUE™ (iohexol) Injection 140 180 240 300 350 140 350 NOT FOR INTRATHECAL USE Section I — Intrathecal Rx ONLY Section II — Intravascular Section III — Oral/Body Cavity Use DESCRIPTION Iohexol,N,N´ -Bis(2,3-dihydroxypropyl)-5-[N-(2,3-dihydroxypropyl)-acetamido]-2,4,6-triiodo- Measuring GFR by iohexol has several advantages: simplicity, low cost, stability and low interlaboratory variation.
