Emergency Room Treatment for Chest Gunshot Wounds
A chest gunshot wound is a medical emergency requiring immediate activation of the emergency response system and rapid intervention to control bleeding and prevent tension pneumothorax. 1
Initial Assessment and Stabilization
- Immediately identify the source of bleeding and perform bleeding control procedures unless initial resuscitation measures are successful 2
- For patients with unidentified sources of bleeding, urgent clinical assessment of chest, abdominal cavity, and pelvic ring status is required 3, 2
- Monitor vital signs including pulse rate, blood pressure, respiratory rate, and mental status to assess hemorrhage severity 3, 2
- Establish large-bore IV access and initiate blood transfusion as needed to replace lost volume 4
Management of Open Chest Wounds
For open chest wounds (wound through chest wall into lung cavity), the following options are reasonable 1:
- Leave the wound exposed to ambient air
- Place a clean, nonocclusive, dry dressing (e.g., gauze dressing)
- Apply a specialized dressing such as a vented chest seal
If a dressing is placed, continuously monitor for worsening breathing or symptoms and loosen or remove the dressing if breathing worsens 1
Be aware that improper use of occlusive dressings can lead to fatal tension pneumothorax by preventing air from exiting through the chest wound 1
Management of Tension Pneumothorax/Hemothorax
- For patients presenting with signs of tension pneumothorax/hemothorax (tracheal shift, congested neck veins, shock, pallor), perform immediate needle thoracostomy at the 2nd intercostal space in the midclavicular line using a needle at least 7-8 cm in length 4
- Follow with tube thoracostomy (chest tube placement) in the 4th/5th intercostal space in the midaxillary line for definitive drainage 4
Imaging Studies
- Chest radiographs can identify contusions, pneumothorax, hemothorax, rib fractures, foreign bodies, and mediastinal injuries requiring immediate treatment 5
- CT with IV contrast is valuable for characterizing penetrating thoracic injuries with a high negative predictive value (up to 99%) in hemodynamically stable patients 5
- CT can identify vascular injuries such as pseudoaneurysms, intimal flaps, filling defects, or contrast extravasation 5, 6
- Pay special attention to injuries in the "cardiac box" (sternal notch superiorly, xiphoid process inferiorly, nipples laterally) as patients with injuries in this region can rapidly decompensate 5
Surgical Intervention
- Penetrating injuries with signs of severe hypovolemic shock specifically require early surgical bleeding control 3, 2
- For gunshot wounds with hemodynamic instability, immediate transfer to the operating theater for surgical bleeding control is recommended 2, 7
- Surgical interventions may include thoracotomy for repair of penetrating injuries to the heart and lungs 8
Ventilation Management
- If mechanical ventilation is required, use protective ventilation with low tidal volume and moderate PEEP, particularly in bleeding trauma patients at risk of acute lung injury 2
- Avoid hypocapnia as it may result in neuronal depolarization and extension of primary injury 2
Common Pitfalls to Avoid
- Inadequate needle length for thoracostomy can lead to improper pleural penetration 4
- Improper needle placement can lead to ineffective decompression 4
- Delaying decompression for other interventions in tension pneumothorax/hemothorax can cause death within minutes 4
- Using fully occlusive dressings that prevent air from escaping can lead to tension pneumothorax 1
