Hence, equivalent amounts of albumin were given. Blood was collected on 15 occasions over 6\u00a0h.

The volume expansion with 20% albumin corresponded to twice the infused volume. One third of the 5% albumin volume quickly leaked out of the plasma, probably because of the higher colloid osmotic pressure of the volunteer plasma (mean, 24.5\u2009mmHg) than the albumin solution (19.1\u2009mmHg). At 6\u00a0h, the capillary leakage amounted to 42\u2009\u00b1\u200915% and 47\u2009\u00b1\u200911% of the administered albumin with the 20% and 5% preparations, respectively (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.28).
