What causes trauma induced coagulopathy?

Trauma-induced coagulopathy (TIC) is a clinical syndrome caused by imbalance between clotting, anti-coagulation and fibrinolysis resulting from multiple pathological factors such as hemorrhage and tissue injury in the early stage of trauma, and is closely related to the outcome of trauma patients.

What is acute traumatic coagulopathy?

Abstract. Acute traumatic coagulopathy (ATC) is an early endogenous process, driven by the combination of tissue injury and shock that is associated with increased mortality and worse outcomes in the polytrauma patient.

Why does shock cause coagulopathy?

Acute Traumatic Coagulopathy occurs immediately after massive trauma when shock, hypoperfusion, and vascular damage are present. Mechanisms for this acute coagulopathy include activation of protein C, endothelial glycocalyx disruption, depletion of fibrinogen, and platelet dysfunction.

What is auto heparinization?

In auto-heparinization, glycocalyx shedding occurs due to endothelial injury, resulting in the release of heparin-like constituents such as circulating heparin sulphate. The decreased protein C levels are replaced by the increased production of activated protein C.

What causes coagulopathy?

Coagulopathy may be caused by reduced levels or absence of blood-clotting proteins, known as clotting factors or coagulation factors. Genetic disorders, such as hemophilia and von Willebrand’s disease, can cause a reduction in clotting factors.

What is acute trauma?

Acute trauma results from a single incident. Chronic trauma is repeated and prolonged such as domestic violence or abuse. Complex trauma is exposure to varied and multiple traumatic events, often of an invasive, interpersonal nature.

What does coagulopathy mean?

Coagulopathy is often broadly defined as any derangement of hemostasis resulting in either excessive bleeding or clotting, although most typically it is defined as impaired clot formation.

What can cause an acquired coagulopathy in pregnancy?

The patient may have developed a coagulopathy acutely secondary to hemodilution, disseminated intravascular coagulation (DIC), or ALFP (Acute Fatty Liver of Pregnancy) Additional reasons for postpartum hemorrhage include placenta accreta, HELLP syndrome and amniotic fluid embolism.

What is the most common cause of coagulopathy?

The most common causes of acquired coagulation disorders are liver disease, vitamin K deficiency, and disseminated intravascular coagulation (DIC). More rarely, inhibitors, external factors such as drugs or extracorporeal circulation, or other diseases such as amyloidosis are present.

How do you identify acute trauma?

Some Common Symptoms of Acute Trauma

1. Panic or extreme anxiety.
2. Confusion or irritation.
3. Dissociation or feeling disconnected from himself and his surroundings.
4. Insomnia or odd sleep patterns.
