Traumatic hemorrhage is a leading
cause of preventable death in patients suffering from severe trauma,
particularly in the first few hours after injury. It is often worsened by
acute
coagulopathy, which arises within minutes of the trauma and contributes to
increased bleeding. Among the early abnormalities observed,
fibrinogen
deficiency is one of the first factors to be altered and is a key determinant
of clot stability.
Despite progress in massive
transfusion protocols, the role of
fibrinogen remains poorly defined. Practices
vary greatly between institutions—both in terms of product choice and
timing of
administration—though timing may be crucial. Some studies suggest that very
early administration, during the initial resuscitation phase, could help
prevent hemodynamic collapse, reduce transfusion requirements, and improve
survival.
However,
direct clinical evidence on
this subject remains limited, fragmented, and sometimes contradictory. The
main
challenge is to robustly demonstrate that early fibrinogen administration
significantly improves clinical outcomes without increasing the risk of
thromboembolic events.
In this context, this study was
initiated to evaluate the effect of
early fibrinogen administration on
mortality, transfusion needs, and adverse events in patients experiencing
severe traumatic hemorrhage.
Early administration... to save more
lives?
Twelve studies were included,
covering a total of
1,657 adult patients with severe traumatic hemorrhage.
Participants were grouped according to the
timing of fibrinogen administration,
defined as within the
first three hours of arrival. The efficacy of the
intervention was assessed using the following outcome variables:
24-hour
mortality, overall in-hospital mortality, transfusion requirements, and
occurrence of adverse thromboembolic events.
The analysis showed that early
administration of fibrinogen is associated with a significant reduction in
24-hour mortality, suggesting a real benefit during the acute phase.
However, no notable difference was observed in overall hospital mortality,
indicating that the immediate benefit may not translate into a long-term
survival advantage. A moderate reduction in transfusion needs was also
observed, which could help limit complications linked to massive transfusions.
Importantly, no increase in thromboembolic risk was found, reinforcing
the safety profile of fibrinogen in the acute phase. Nonetheless, the results
showed some heterogeneity due to variations in the products used and protocols
applied across different study settings.
Emergency fibrinogen: a future
standard of care?
Traumatic hemorrhage is one of the
main preventable causes of death in emergency medicine, often worsened by
acute
coagulopathy, particularly early fibrinogen deficiency. The major challenge in
this pathology lies in timely intervention to correct the deficit by optimizing
hemostatic management within the first hours.
The objective of this review was to
assess the effectiveness of early fibrinogen administration in reducing
mortality and transfusion needs in patients with traumatic bleeding. The
findings suggest a real benefit in terms of 24-hour mortality and a moderate
reduction in transfusions, without an increased thromboembolic risk.
However, the effect on overall hospital mortality remains uncertain, and
the heterogeneity of protocols limits the generalizability of the
conclusions.
To move forward,
large-scale
prospective trials are needed to standardize practices, identify the patients
who would benefit the most from this strategy, and validate fibrinogen as a
reference early intervention in traumatic hemorrhage management protocols.
