Effect of the carrier solution for hydroxyethyl starch on platelet aggregation and clot formation

The carrier solution for HES up to 20 ml kg−1 had little impact on platelet aggregation or clot formation as assessed by MEA and rotational thrombelastometry, respectively. Further clinical studies are required to verify this finding in patients and to correlate results of whole blood aggregometry and rotational thrombelastometry with perioperative bleeding and transfusion requirements.
