In this scenario, the patient presents with symptoms indicative of a tension pneumothorax: hypotension, respiratory distress, subcutaneous emphysema, and no air entry on one side. A tension pneumothorax is a critical condition where air becomes trapped in the pleural space and cannot escape, leading to increased pressure that impairs cardiorespiratory function. Immediate intervention is necessary to relieve this pressure.
The best initial management is needle decompression. This procedure involves:
- Identifying the correct site: The 5th intercostal space, midaxillary line is used.
- Preparing the tools: Use a large-bore needle or cannula (often 14-gauge) to ensure adequate decompression.
- Inserting the needle: Insert perpendicular to the chest wall to penetrate the pleural space and allow air to escape.
After decompression, further treatment often involves the insertion of a chest tube to ensure continued evacuation of air and re-expansion of the lung.
