Science Education: Physical Trauma and Sepsis
Studies on physical trauma and sepsis, the body's overwhelming immune response to severe injury or infection, focus on questions like:
- What changes occur immediately and over time when a person is critically ill or injured?
- Why does the immune system go into overdrive?
- How can we improve diagnosis and treatment strategies?
