Implication

Retrospective cohort study demonstrates thromboelastography rapidly identifies coagulopathy in postpartum hemorrhage, indicating potential for faster targeted hemostatic interventions.

Key Points

To evaluate the diagnostic accuracy and turnaround time of standard and velocity curve-derived thromboelastography parameters for detecting coagulation disorders and severe bleeding during postpartum hemorrhage.
Retrospective observational cohort study of 98 women with ongoing postpartum hemorrhage exceeding 500 mL who had simultaneous thromboelastography (TEG) and standard laboratory coagulation tests.
Assessed classical and velocity-derived TEG parameters—Kaolin-maximum amplitude (K-MA), Kaolin-maximum rate of thrombus generation (K-MRTGG), functional fibrinogen-maximum amplitude (FF-MA), and functional fibrinogen-maximum rate of thrombus generation (FF-MRTGG)—to identify hypofibrinogenemia (≤2 g/L) and thrombocytopenia (≤80,000/mm³).
Kaolin assay metrics demonstrated high predictive accuracy for hypofibrinogenemia or thrombocytopenia without significant difference between parameters (K-MA AUC 0.970 vs K-MRTGG AUC 0.981).
Functional fibrinogen parameters showed comparable diagnostic accuracy for hypofibrinogenemia (FF-MA AUC 0.988 vs FF-MRTGG AUC 0.974), and all TEG parameters significantly predicted severe postpartum hemorrhage greater than 2500 mL.
Velocity parameters produced results significantly faster than standard parameters (K-MRTGG 7.7 min vs K-MA 24.7 min, P < .001; FF-MRTGG 2.7 min vs FF-MA 14.0 min, P < .001).
