Summary of "Trauma-associated hyperfibrinolysis."
Trauma-induced coagulopathy (TIC) has been considered for a long time as being due to depletion of coagulation factors secondary to blood loss, dilution and consumption. Dysfunction of the remaining coagulation factors due to hypothermia and acidosis is assumed to additionally contribute to TIC. Recent data suggest that hyperfibrinolysis (HF) represents an additional important confounder to the disturbed coagulation process. Severe shock and major tissue trauma are the main drivers of this HF. The incidence of HF is still speculative. According to visco-elastic testing of trauma patients upon emergency room admission, HF is present in approximately 2.5-7% of all trauma patients. However, visco-elastic tests provide information on severe forms of HF only. Occult HF seems to be much more common but diagnosis is still challenging. Results from a recent randomized, placebo-controlled trial suggest that the early treatment of trauma patients with tranexamic acid may result in a significant reduction of trauma-associated mortality.

Medical and Biotech [MESH] Definitions
Specialized hospital facilities which provide diagnostic and therapeutic services for trauma patients.
Carotid Artery Injuries
Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION.

Trauma Severity Indices
Systems for assessing, classifying, and coding injuries. These systems are used in medical records, surveillance systems, and state and national registries to aid in the collection and reporting of trauma.
Cranial Nerve Injuries
Dysfunction of one or more cranial nerves causally related to a traumatic injury. Penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA; NECK INJURIES; and trauma to the facial region are conditions associated with cranial nerve injuries.
Abducens Nerve Injury
Traumatic injury to the abducens, or sixth, cranial nerve. Injury to this nerve results in lateral rectus muscle weakness or paralysis. The nerve may be damaged by closed or penetrating CRANIOCEREBRAL TRAUMA or by facial trauma involving the orbit.
Recent studies identify a survival benefit from the administration of antifibrinolytic agents in patients with severe injury and trauma. However, identification of hyperfibrinolysis requires thromboel...
Hyperfibrinolysis (HF) has been reported to occur in a range of 2% to 34% of trauma patients. Using rapid thromboelastography (r-TEG), we hypothesized that HF is (1) rarely present at admission on pat...

Even nowadays and at specialized centers, one of the leading causes of death is exsanguination. Trauma-induced coagulopathy (TIC) occuring with massive blood loss primarily results from loss of coagua...
