During triage after a stab wound, which organs are at increased risk for injury?

• A. Liver, spleen
• B. Kidneys
• C. Heart, lungs, diaphragm
• D. Pancreas

Answer: (C)

Penetrating trauma to the chest puts organs inside the thoracic cavity at immediate risk. The heart can suffer injury leading to tamponade or shock, the lungs can be punctured causing pneumothorax or hemorrhage, and the diaphragm can be torn if the wound crosses into the thoracoabdominal area, raising the possibility of abdominal contents moving into the chest. In triage, these thoracic injuries demand swift assessment and management because they can rapidly compromise breathing and circulation. In contrast, kidneys are tucked in the retroperitoneum and are less likely to be injured by a typical chest stab, and the pancreas lies deeper in the upper abdomen, making injuries to them less likely from a chest wound. So the organs at increased risk are the heart, lungs, and diaphragm.
