Several methods are used to analyse platelet function in whole blood. A new device to measure whole blood platelet aggregation has been developed, called multiple electrode platelet aggregometry… Expand
Utility of whole blood impedance aggregometry for the assessment of clopidogrel action using the novel Multiplate analyzer--comparison with two flow cytometric methods.
BACKGROUND Non-responsiveness to anti-platelet therapy has been reported and has been linked to the occurrence of adverse events. No standard method to monitor clopidogrel efficacy is available at… Expand
Citrate Anticoagulation for Extracorporeal Circuits: Effects on Whole Blood Coagulation Activation and Clot Formation
Dear Sir, Adequate anticoagulation is a precondition for any effective hemodialysis therapy to prevent clotting in the extracorporeal circuit. While systemic anticoagulation with unfractionated… Expand

Background: Hydroxyethyl starches (HES) are known to interfere with blood coagulation according to molecular weight, the degree of substitution and the C2/C6 ratio. A recently developed low molecular… Expand

BackgroundPoor platelet inhibition by aspirin or clopidogrel has been associated with adverse outcomes in patients with cardiovascular diseases. A reliable and facile assay to measure platelet… Expand
The Effect of the Combined Administration of Colloids and Lactated Ringer’s Solution on the Coagulation System: An In Vitro Study Using Thrombelastograph® Coagulation Analysis (ROTEG®)
Gelatin solutions are often given in clinical practice once the maximal dose of a median-weight hydroxyethyl starch (HES) has been reached. Colloids are usually combined with lactated Ringer’s… Expand
Fibrinogen Concentrate Reverses Dilutional Coagulopathy Induced In Vitro by Saline but Not by Hydroxyethyl Starch 6%
Severe bleeding often induces coagulopathy via loss, consumption, and dilution of clotting factors and platelets. The aims of our in vitro study were to characterize the influence of progressive… Expand
Prothrombinase-induced clotting time assay for determination of the anticoagulant effects of unfractionated and low-molecular-weight heparins, fondaparinux, and thrombin inhibitors.
