Question: 1 / 400

How much blood loss can occur from a long bone fracture?

200-500 mL

500-1000 mL

1-2 L

A long bone fracture can lead to significant blood loss due to the large vascular supply associated with these bones and the potential disruption of blood vessels during a fracture. It is estimated that the amount of blood loss can range from 1 to 2 liters in severe cases, particularly when multiple fractures are involved or if there is associated soft tissue injury.

This amount of blood loss can markedly affect hemodynamics, leading to hypovolemic shock if not addressed promptly. Understanding the volume of potential blood loss from such fractures is critical for trauma management. The high volume of possible hemorrhage is crucial for guiding fluid resuscitation and blood transfusion decisions in a trauma scenario.

In contrast, the other options reflect lower estimates that are less aligned with the actual physiological impact associated with a long bone fracture.
