Meta Analysis Comparative StudyThe effects of hydroxyethyl starch 130/0.4 (6%) on blood loss and use of blood products in major surgery: a pooled analysis of randomized clinical trials.
The effects of different types of hydroxylethyl starch (HES) on blood coagulation closely depend on their physicochemical properties. HES with lower molar substitution and a lower in vivo molecular weight interferes relatively little with hemostasis and therefore results in lower perioperative blood losses and red blood cell (RBC) transfusion. To test this hypothesis, we analyzed pooled data from all available studies in major surgery comparing 6% HES 130/0.4 and 6% HES 200/0.5 from waxy maize starch. ⋯ Blood loss and transfusion requirements can be significantly reduced in major surgery when using third generation HES 130/0.4 (Voluven) compared to second generation waxy maize starch HES 200/0.5. Since HES 130/0.4 and HES 200/0.5 were found similar regarding volume efficacy in other studies, HES 130/0.4 is recommended in this clinical setting.
