Analyzing coagulability often hinges on patient surveillance using prothrombin time (PT) or international normalized ratio (INR) and activated partial thromboplastin time (aPTT) to monitor the extrinsic and intrinsic coagulation pathways, respectively A more complete assessment, however, can often be obtained using thromboelastography (TEG), a coagulation assay that evaluates the efficiency of ...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether use of thromboelastography could predict and decrease bleeding and blood and blood product requirements in adult patients undergoing cardiac surgery. Altogether 170 papers were identified using the reported search strategy of which 14 represented the best evidence on the t...

Amniotic fluid embolism is a rare obstetric complication. The exact pathogenesis of this syndrome remains unknown and significant controversy exists whether coagulopathy should always be present. We used thromboelastography to assess the effect of amniotic fluid on coagulation and platelet function in pregnant women. Different volumes of amniotic fluid (10-60 microl) were added to blood (330 mi...

Thromboelastography (TEG) using disposable plastic cups and pins was performed with native whole blood (native group) in 17 nonpregnant volunteers, 134 healthy term pregnant women (>36 wk gestation), and 69 postpartum women. Thromboelastography was also performed with celite-activated whole blood (celite group) in 15 nonpregnant female volunteers, 38 healthy term pregnant women, and 34 postpart...

metry (‘ROTEM’) are used increasingly in cardiac and liver surgery to evaluate clotting factor deficiencies and platelet dysfunction. 7 Both monitor viscoelastic properties of whole blood as it is induced to clot in a low-shear environment (resembling sluggish venous flow) and provide valuable information on haemostasis from initiation to fibrinolysis. Our case illustrates the limitations that ...

The objective: to evaluate the standard indicators of thromboelastometry in pregnant women with placental dysfunction. Materials and methods. Venous blood samples 26 healthy (control group) 50 patients dysfunction (main group, persons 19–40 years old) were examined. average gestation period at time study was 29.5±7.2 32.9±4.4 weeks, respectively. Standard coagulation tests (coagulogram) rotatio...
