Signs and symptoms

- Uncontrolled internal or external bleeding - Damage to joints, muscles, or internal organs - Life-threatening if left untreated - Serious symptoms include heavy external bleeding, blood in urine or stool, double vision, severe head or neck pain, repeated vomiting, difficulty walking, convulsions, or seizures - Prompt medical care needed for mild but unstoppable external bleeding or joint swelling and stiffness

Mechanism

- Coagulopathy caused by reduced levels or absence of clotting factors - Genetic disorders like hemophilia and Von Willebrand disease can cause reduced clotting factors - Anticoagulants like warfarin prevent proper clot formation - Dysfunction or reduced levels of platelets can lead to coagulopathy - The normal clotting process depends on the interplay of various proteins in the blood

Acute traumatic coagulopathy

- Coagulopathy induced by trauma results in more severe bleeding - It can lead to multi-organ failure - High mortality rates associated with acute traumatic coagulopathy - Coined by Karim Brohi, Professor of Trauma Sciences - Identified as a significant factor in trauma-related outcomes

Treatment

- Medications or replacement therapy used to manage coagulopathy symptoms - Replacement therapy involves replacing reduced or absent clotting factors with proteins derived from human blood or created in the laboratory - Therapy can be given to treat ongoing bleeding or prevent future bleeding - Health care provider helps manage coagulopathy treatment - Prompt medical care and intervention necessary for effective treatment

Critical care

- Managing major bleeding in critical settings like emergency departments - Transfusion of red cells combined with blood plasma or specific clotting factors - Tranexamic acid supported by large, randomised clinical trial for major bleeding after trauma - Possible risks associated with treating coagulopathies, such as transfusion-related acute lung injury, acute respiratory distress syndrome, multiple organ dysfunction syndrome, major hemorrhage, and venous thromboembolism - Updated European guidelines provide recommendations for managing bleeding and coagulopathy following major trauma.
