NCT00493272

Brief Summary

The purpose of the present study is to perform a comprehensive description of haemostasis parameters before and after haemodilution with Hydroxyethyl starch (HES) following acute bleeding during elective surgery. Moreover the study aims to test the in vivo haemostatic potential of fibrinogen concentrate in dilutional coagulopathy caused by HES in a clinical, prospective, placebo-controlled randomised setup. We hypothesise; a) A coagulopathy is induced following in vivo haemodilution; b) the coagulopathy is improved or partially improved by fibrinogen.
