Key result
TEG and RoTEM measurements were not completely interchangeable in cardiac surgical patients, as reaction time was significantly longer with kaoTEG (345s) compared to inTEM (179s, P<0.001).
Why the study?
Are TEG and RoTEM thromboelastographic variables clinically interchangeable in cardiac surgical patients?
Population
46 cardiac surgical patients (blood samples taken after induction of anesthesia) and 2 volunteers
Comparison
Thromboelastography using TEG system vs Thromboelastometry using RoTEM system
Design
Cross-sectional

TEG and RoTEM require device-specific interpretation in cardiac surgical patients; challenges interchangeability assumptions and supports platform-specific validation.

Are TEG and RoTEM thromboelastographic variables clinically interchangeable in cardiac surgical patients?
TEG and RoTEM systems are not completely interchangeable for measuring coagulation parameters in cardiac surgical patients, and their data should be interpreted with caution.
Venema et al. (2010) conducted an observational in Cardiac surgical patients (n=46). TEG (Hemoscope) vs. RoTEM (Pentapharm) was evaluated on Clinical interchangeability of thromboelastographic variables (R, K, MA, alpha). TEG and RoTEM measurements were not completely interchangeable in cardiac surgical patients, as reaction time was significantly longer with kaoTEG (345s) compared to inTEM (179s, P<0.001).
