The authors investigated the impact of acute normovolemic hemodilution (ANH) on intrarenal oxygenation and its functional short-term consequences in pigs. ⋯ ANH to a hematocrit of 15% statistically significantly impaired µPO2 and renal function in the crystalloid group. Less tissue edema formation and an unimpaired renal µPO2 in the colloid group might account for a preserved renal function.
