Volumes of colloids were given based on clinical indication. Blood samples were obtained.

It remained unchanged in the Albumin group (29.2\u2003g\/l). The two groups were analyzed with the pre\u2010operative sample acting as the control. In the starch group, the percent free concentration of the drugs increased significantly (<jats:italic>P<\/jats:italic>&lt;0.01): for naproxen from 0.2% to 0.6%, for warfarin from 1.2% to 1.8% and for digitoxin from 6.8% to 11.1%. In the Albumin group, the % free fraction of naproxen doubled from 0.1% to 0.2% (<jats:italic>P<\/jats:italic>&lt;0.05), whereas the % free fraction of warfarin decreased from 1.1% to 1.0% (<jats:italic>P<\/jats:italic>&lt;0.05).
