Hemodilution and Coagulopathy With 3 Colloids

Switzerland12 participantsStarted 2012-06

Plain-language summary

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. * Trial with medical device
