[Second increase in plasma volume after single infusion of hydroxyethyl starch (author's transl)].
6 patients without evidence for renal, hepatic or pancreatic disease were treated with intravenous infusions of 500 ml hydroxyethyl starch (6%) over a period of 60 min. In the course of the infusion we observed an increase in plasma volume from 2.72 +/- 0.101 to 3.36 +/- 0.141. After 2 h plasma volume decreased to 3.02 +/- 0.101 but showed a second peak of 3.23 +/- 0.121 after 4 h (p less than 0.01). 24 h following infusion an increase in plasma volume of 4,8% was found as compared to preinfusion values. ⋯ This is caused by the formation of a high molecular hydroxyethyl starch-amylase-complex which cannot be eliminated easily. When hydroxyethyl starch is given repeatedly to normovolemic patients, the second increase in plasma volume should be considered as a possible cause for acute hypervolemia. This is especially true for patients with myocardial insufficiency.
