What symptom is associated with significant TBI that would warrant TXA administration?

The administration of TXA (Tranexamic Acid) in the context of significant Traumatic Brain Injury (TBI) is particularly focused on clinical signs that indicate a severe level of trauma and risk of hemorrhage. Altered mental status is a critical symptom because it suggests that there is a disruption in brain function, possibly due to injury, which can be indicative of significant intracranial bleeding or edema.

In cases of significant TBI, the brain is vulnerable to bleeding, and this can lead to a cascade of secondary injuries. An altered mental state illustrates that the injury is affecting cognitive function and might be associated with increased intracranial pressure or hematoma. This is why recognizing altered mental status is important as it can trigger interventions, such as the administration of TXA, which help to reduce the risk of bleeding and improve outcomes.

Headaches can occur with less severe TBIs and are not always indicative of significant injury requiring medical intervention. Signs of shock are associated with systemic blood loss and could indicate multiple injuries beyond just TBI, making it a broader consideration. Unconsciousness can be a severe indicator of injury but does not directly correlate with the need for TXA in TBI cases. Ultimately, altered mental status specifically highlights a change linked
