The pathogenesis of traumatic coagulopathy

Area of Science:

• Trauma Management
• Hemorrhage Control
• Coagulopathy Research

Background:

• Major hemorrhage management in trauma has evolved significantly over the past decade.
• Recognition of pre-existing coagulopathy in bleeding trauma patients, termed acute traumatic coagulopathy (ATC), predates fluid resuscitation hemodilution.
• ATC is a critical prognostic indicator associated with adverse clinical outcomes in trauma patients.

Purpose of the Study:

• To discuss the paradigm shift in trauma hemorrhage management.
• To highlight the importance of recognizing and managing acute traumatic coagulopathy.
• To explore the multifaceted pathophysiology contributing to trauma-induced coagulopathy.

Main Methods:

• Review of current literature and clinical practices in trauma hemorrhage management.
• Discussion of the evolving understanding of acute traumatic coagulopathy.
• Analysis of factors contributing to coagulopathy in trauma patients.

Main Results:

• The clinical approach has changed from secondary management of coagulopathy to early hemostatic resuscitation.
• Prolongation of prothrombin time is a commonly used indicator for coagulopathy.
• Multiple factors including hypoxia, acidosis, hypothermia, and physiological responses contribute to ATC.

Conclusions:

• Early recognition and hemostatic resuscitation are crucial for improving outcomes in trauma patients with major hemorrhage.
• Understanding the complex pathophysiology of ATC is essential for effective clinical management.
• The management strategy has fundamentally changed to prioritize immediate hemostasis.
