A 22-year-old man is brought to the emergency department by emergency medical services after a high-speed motor vehicle collision. He is in severe respiratory distress and is unable to speak in full sentences. His blood pressure is 80/40 mm Hg, pulse is 135/min, and respirations are 36/min. Oxygen saturation is 84% on room air. Physical examination reveals distended neck veins, absent breath sounds over the right hemithorax, and tracheal deviation to the left side. Which of the following is the most appropriate next step in management?
- Perform immediate needle or finger thoracostomyCevap
- BObtain an urgent portable chest radiograph
- COrder computed tomography angiography of the chest
- DAdminister intravenous metoprolol
- EPerform a transesophageal echocardiogram
Cevap
Perform immediate needle or finger thoracostomy
The patient presents with classic signs of a tension pneumothorax: severe respiratory distress, hypotension, tachycardia, distended neck veins, absent breath sounds on one side, and tracheal deviation away from the affected side. The increased intrathoracic pressure compresses the superior and inferior vena cava, decreasing venous return and causing obstructive shock. Tension pneumothorax is a life-threatening emergency and must be diagnosed clinically. The most appropriate next step is immediate decompression of the pleural space via needle thoracostomy, finger thoracostomy, or tube thoracostomy. Treatment must never be delayed for imaging in an unstable patient.
