How should a penetrating chest wound without signs of tension be managed?

• A. Immediate needle decompression
• B. Leave wound open to air
• C. Administer broad-spectrum antibiotics
• D. Occlusive dressing or vented chest seal; monitor closely for signs of tension

Answer: (D)

Preventing air from entering the chest while staying alert for evolving tension is the guiding approach. With a penetrating chest wound and no signs of tension, seal the wound with an airtight dressing or use a vented chest seal. This creates a one-way barrier: it stops air from being sucked into the pleural space during inhalation, while still allowing air to escape if a developing pneumothorax occurs. You should monitor closely for signs of tension, such as increasing shortness of breath, chest pain, hypotension, distended neck veins, or tracheal deviation, and be prepared to escalate care if those signs appear. Immediate needle decompression isn’t indicated here because there are no signs of tension yet. Leaving the wound open to air can worsen air entry and is not preferred, and broad-spectrum antibiotics aren’t the immediate priority for an uncomplicated penetrating chest wound unless later indications arise.
