Hemodilution and Coagulopathy With 3 Colloids
Aim of this in vitro trial is to assess the effect on blood coagulation after 60 % dilution with different colloids (HES 130/0.42, Gelatin and Gelatin balanced) and investigate reversibility by replacement of fibrinogen (FBG), factor XIII (F XIII), and the combination of FBG and FXIII.
In blood of 12 volunteers the following measurements are performed at baseline and 60% dilution with HES 130/0.42, Gelatin or Gelatin balanced: Blood gas analyses, coagulation factor concentrations (F II,F VII,F VIII,F XIII), impedance aggregometry and rotational thrombelastometry (ROTEM®). Then FBG, F XIII and a combination of both was added, in concentrations corresponding to 6 g FBG and 1250 IU F XIII in adults. ROTEM® measurements and determination of factor concentrations are again performed.

|Official Title:||Influence of Hemodilution on Coagulation, pH, Platelet Function, Laboratory Values and ROTEM in Volunteers Using HES 6%, Gelatine and Balanced Gelatine and the Reversal of Coagulopathy With F XIII and Fibrinogen|
- Reversibility of in vitro induced coagulopathy [ Time Frame: Same day when blood was drawn ]Coagulopathy in vitro measured after 60 % dilution with HES, Gelatin and Gelatin balanced. Addition of fibrinogen and factor XIII as well as their combination and measurement if the coagulopathy was corrected.

- This trial is in vitro and made with blood of healthy volunteers.
- Thus no drug no intervention beside drawing blood is beeing performed.
