Advice
  • In patients who get chest x-ray and CT is being considered, the NEXUS creators recommend using the NEXUS Chest CT Decision Instrument.
  • Adequate pain control is always important in patients with trauma.
  • Consider initial evaluation with chest x-ray in stable patients with isolated chest trauma.
  • CT will obviously find many more injuries than x-ray, regardless of their true clinical significance.
  • CT may be more useful in patients with multiple injuries or those who are sicker.
