ROTEM
Pronunciation: ROH-tem
Also written as: ROTEM — rotational thromboelastometry
Rotational thromboelastometry device providing real-time assessment of blood coagulation and clot formation properties.
Full Definition
ROTEM (rotational thromboelastometry) is a point-of-care viscoelastic testing system that analyzes whole blood coagulation by measuring clot formation, strength, and dissolution in real-time. In cardiac surgery, ROTEM guides targeted blood product therapy by identifying specific coagulation defects such as factor deficiency, platelet dysfunction, or fibrinolysis. The system provides multiple parameters including clotting time, clot formation time, alpha angle, and maximum clot firmness, allowing for more precise hemostatic management than traditional coagulation tests during and after cardiopulmonary bypass.
Usage
Usage note: Include specific ROTEM parameters when documenting coagulation assessment findings.
