Hepatic ICG removal in the pig depends on plasma protein and hematocrit: Evidence of sinusoidal binding disequilibrium and unstirred water layer effects
P Ott, L Bass, S Keiding – 30 December 2003 – The influence of binding protein concentration and hematocrit on hepatic uptake of indocyanine green (ICG) was studied in anesthetized pigs during constant infusion of ICG. By exchange transfusions, we either substituted plasma protein with dextran 70 (n = 8) or changed hematocrit (n = 8). Intrinsic hepatic clearance of ICG, K, was calculated from plasma flow rate and concentrations in peripheral artery and liver vein after correction for extrahepatic distribution.
