What mechanism of injury could classify a case as MTV?

In the context of trauma assessment, MTV stands for "Mechanism of Injury – Trauma Victims." Identifying the mechanism of injury is crucial in determining the severity of trauma and the necessary interventions. The option that includes prolonged extrication required to free the victim serves as a significant indicator of potential severe injuries.

When prolonged extrication is needed, it suggests that the victim may have been involved in a high-impact or complex accident, which raises the likelihood of serious internal injuries or fractures. This situation often implies that the victim was trapped in a vehicle for an extended period, which can exacerbate trauma-related complications and increase the risk of hemorrhagic shock and other critical conditions.

In contrast, factors like impact speed, the death of a passenger in another vehicle, and ejection from a vehicle indicate trauma risk but do not directly reflect the situation where extended extrication itself signals a high potential for severe injuries. Thus, prolonged extrication serves as a robust criterion for classifying a case as MTV based on the seriousness and complexity of the injury mechanism.
