Among the numerous components of the University of Wisconsin (UW) solution used for organ preservation, the usefulness of hydroxyethylstarch (HES), the colloido‐osmotic support of this solution, is controversial. The aim of our study was to determine the influence of HES on hepatic metabolism and intracellular hydration state during hypothermic preservation and after reperfusion in a model of isolated perfused rat liver. Three groups of eight livers were perfused either immediately or after 18 hours of cold storage in a UW‐ based preservation solution with or without HES. Omission of HES results in (1) a stimulation of protein degradation shown by the marked increase in branched‐chain amino acid (BCAA) release (211 ± 55 vs. 87 ± 28 nmol/min/g; P < .05, modified UW group vs. UW group), (2) an increase in oxygen consumption (81.7 ± 4.8 vs. 61.5 ± 5.0 µmol/h/g; P < .05), (3) a decrease in glucose production (2.3 ± 0.6 vs. 5.0 ± 0.6 µmol/min/g; P < .05), and (4) a reduction in intracellular volume (414 ± 36 vs. 557 ± 41 µL/g; P < .05). We conclude that HES plays an important role in liver preservation by limiting proteolysis, possibly through the observed preservation of cell volume.
