Which is the most life-threatening complication mentioned with open neck injuries?

• A. Infection
• B. Hematoma
• C. Pneumothorax
• D. Air embolism

Answer: (D)

Open neck wounds create a direct channel for air to enter torn veins. When air gets into the venous system, it can travel to the right side of the heart and into the pulmonary circulation, where it can form an air embolus that blocks blood flow. This can lead to sudden respiratory distress, a drop in blood pressure, and even cardiac arrest in a very short time. Infection and hematoma are concerns, but they tend to develop more gradually and aren’t as immediately life-threatening. Pneumothorax is serious as well, but the rapid, dramatic collapse from an air embolism makes it the most dangerous complication in this scenario. In the field, focus on preventing further air entry, provide high-flow oxygen, monitor the patient, and transport quickly to a trauma center.
