A simple fibrinogen measurement can predict severe postpartum hemorrhage (PPH) risk. Lower fibrinogen levels at any time point indicate a higher likelihood of severe bleeding in PPH patients.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Maternal Health
Background:
- Postpartum hemorrhage (PPH) is a significant cause of maternal morbidity worldwide.
- Early identification of severe PPH cases is crucial for timely intervention and improved outcomes.
Purpose of the Study:
- To investigate the predictive value of hemostasis markers for PPH severity.
- To determine if changes in coagulation parameters correlate with the degree of postpartum bleeding.
Main Methods:
- 128 women with PPH were enrolled, with severe PPH defined by 24-hour outcomes.
- Serial coagulation tests (fibrinogen, factor V, PT, D-dimer, TAT, etc.) were performed at multiple time points (H0, H1, H2, H4, H24).
- Multivariate analysis was used to identify significant predictors of severe PPH.
Main Results:
- Women with severe PPH exhibited lower fibrinogen, factor V, antithrombin, and protein C levels, alongside prolonged prothrombin time and elevated D-dimer and TAT complexes compared to non-severe cases.
- Fibrinogen levels were the sole marker significantly associated with severe PPH from H0 to H4.
- A fibrinogen level
4 g/L had a 79% negative predictive value.
Conclusions:
- Fibrinogen level is a reliable and simple marker for anticipating the risk of severe postpartum hemorrhage.
- Early fibrinogen measurement can aid clinicians in risk stratification and management of PPH.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
