How should an open sucking chest wound be managed to prevent air entry and progression to tension pneumothorax?

• A. Apply an occlusive dressing taped on three sides (flutter valve) and monitor; prepare for chest tube if deterioration occurs
• B. Leave wound open to air
• C. Apply simple dressing with no pressure
• D. Cover with airtight seal on all sides

Answer: (A)

The key idea here is preventing air from being drawn into the chest while giving any trapped air a way to escape, so the intrathoracic pressure doesn’t rise to a dangerous level. An open sucking chest wound is treated with an occlusive dressing that’s taped on three sides, creating a flutter-valve effect. The dressing seals around the wound but leaves one edge open enough to vent air out as the patient exhales; when the patient inhales, the partial seal helps keep outside air from rushing into the pleural space. This minimizes the risk of progression to a tension pneumothorax and buys time while monitoring and preparing for chest tube if the situation worsens. Leaving the wound open to air would allow air to enter with inspiration, increasing the pneumothorax risk. A simple dressing with no pressure won’t prevent air entry or venting. Sealing on all sides creates an airtight seal that can trap air inside the chest, potentially causing tension pneumothorax.
